"NAME\n"
" curl - get a URL with FTP, TELNET, LDAP, GOPHER, DICT, FILE,\n"
" HTTP or HTTPS syntax.\n"
"\n"
"SYNOPSIS\n"
" curl [options] url\n"
"\n"
"DESCRIPTION\n"
" curl is a client to get documents/files from servers, using\n"
" any of the supported protocols. The command is designed to\n"
" work without user interaction or any kind of interactivity.\n"
" curl offers a busload of useful tricks like proxy support,\n"
" user authentication, ftp upload, HTTP post, SSL (https:)\n"
" connections, cookies, file transfer resume and more.\n"
"\n"
"URL\n"
" The URL syntax is protocol dependent. You'll find a detailed\n"
" description in RFC 2396.\n"
"\n"
" You can specify multiple URLs or parts of URLs by writing\n"
" part sets within braces as in:\n"
"\n"
" http://site.{one,two,three}.com\n"
"\n"
" or you can get sequences of alphanumeric series by using []\n"
" as in:\n"
"\n"
" ftp://ftp.numericals.com/file[1-100].txt\n"
" ftp://ftp.numericals.com/file[001-100].txt (with leading\n"
" zeros)\n"
" ftp://ftp.letters.com/file[a-z].txt\n"
"\n"
" It is possible to specify up to 9 sets or series for a URL,\n"
" but no nesting is supported at the moment:\n"
"\n"
" http://www.any.org/archive[1996-1999]/vol\n"
" ume[1-4]part{a,b,c,index}.html\n"
"\n"
"OPTIONS\n"
" -a/--append\n"
" (FTP) When used in a ftp upload, this will tell curl to\n"
" append to the target file instead of overwriting it. If\n"
" the file doesn't exist, it will be created.\n"
"\n"
" -A/--user-agent <agent string>\n"
" (HTTP) Specify the User-Agent string to send to the\n"
" HTTP server. Some badly done CGIs fail if its not set\n"
" to \"Mozilla/4.0\". To encode blanks in the string, sur\n"
" round the string with single quote marks. This can\n"
" also be set with the -H/--header flag of course.\n"
" -b/--cookie <name=data>\n"
" (HTTP) Pass the data to the HTTP server as a cookie. It\n"
" is supposedly the data previously received from the\n"
" server in a \"Set-Cookie:\" line. The data should be in\n"

" the format \"NAME1=VALUE1; NAME2=VALUE2\".\n"
"\n"
" If no '=' letter is used in the line, it is treated as\n"
" a filename to use to read previously stored cookie\n"
" lines from, which should be used in this session if\n"
" they match. Using this method also activates the\n"
" \"cookie parser\" which will make curl record incoming\n"
" cookies too, which may be handy if you're using this in\n"
" combination with the -L/--location option. The file\n"
" format of the file to read cookies from should be plain\n"
" HTTP headers or the netscape cookie file format.\n"
"\n"
" -B/--ftp-ascii\n"
" (FTP/LDAP) Use ASCII transfer when getting an FTP file\n"
" or LDAP info. For FTP, this can also be enforced by\n"
" using an URL that ends with \";type=A\".\n"
"\n"
" -c/--continue\n"
" Continue/Resume a previous file transfer. This\n"
" instructs curl to continue appending data on the file\n"
" where it was previously left, possibly because of a\n"
" broken connection to the server. There must be a named\n"
" physical file to append to for this to work. Note:\n"
" Upload resume is depening on a command named SIZE not\n"
" always present in all ftp servers! Upload resume is for\n"
" FTP only. HTTP resume is only possible with HTTP/1.1\n"
" or later servers.\n"
"\n"
" -C/--continue-at <offset>\n"
" Continue/Resume a previous file transfer at the given\n"
" offset. The given offset is the exact number of bytes\n"
" that will be skipped counted from the beginning of the\n"
" source file before it is transfered to the destination.\n"
" If used with uploads, the ftp server command SIZE will\n"
" not be used by curl. Upload resume is for FTP only.\n"
" HTTP resume is only possible with HTTP/1.1 or later\n"
" servers.\n"
"\n"
" -d/--data <data>\n"
" (HTTP) Sends the specified data in a POST request to\n"
" the HTTP server. Note that the data is sent exactly as\n"
" expected to be \"url-encoded\". This will cause curl to\n"
" pass the data to the server using the content-type\n"
" application/x-www-form-urlencoded. Compare to -F.\n"
"\n"
" If you start the data with the letter @, the rest\n"
" should be a file name to read the data from, or - if\n"
" you want curl to read the data from stdin. The con\n"
" tents of the file must already be url-encoded.\n"
"\n"
" -D/--dump-header <file>\n"
" (HTTP/FTP) Write the HTTP headers to this file. Write\n"
" the FTP file info to this file if -I/--head is used.\n"
"\n"
" -e/--referer <URL>\n"
" (HTTP) Sends the \"Referer Page\" information to the HTTP\n"
" server. Some badly done CGIs fail if it's not set. This\n"
" can also be set with the -H/--header flag of course.\n"
"\n"
" -E/--cert <certificate[:password]>\n"
" (HTTPS) Tells curl to use the specified certificate\n"
" file when getting a file with HTTPS. The certificate\n"
" must be in PEM format. If the optional password isn't\n"
" specified, it will be queried for on the terminal. Note\n"
" that this certificate is the private key and the pri\n"
" vate certificate concatenated!\n"
" (HTTP) Fail silently (no output at all) on server\n"
" errors. This is mostly done like this to better enable\n"
" scripts etc to better deal with failed attempts. In\n"
" normal cases when a HTTP server fails to deliver a doc\n"
" ument, it returns a HTML document stating so (which\n"
" often also describes why and more). This flag will pre\n"
" vent curl from outputting that and fail silently\n"
" instead.\n"
"\n"
" -F/--form <name=content>\n"
" (HTTP) This lets curl emulate a filled in form in which\n"
" a user has pressed the submit button. This causes curl\n"
" to POST data using the content-type multipart/form-data\n"
" according to RFC1867. This enables uploading of binary\n"
" files etc. To force the 'content' part to be read from\n"
" a file, prefix the file name with an @ sign. Example,\n"
" to send your password file to the server, where 'pass\n"
" word' is the name of the form-field to which\n"
" /etc/passwd will be the input:\n"
"\n"
" curl -F password=@/etc/passwd www.mypasswords.com\n"
"\n"
" To read the file's content from stdin insted of a file,\n"
" use - where the file name should've been.\n"
"\n"
" -h/--help\n"
" Usage help.\n"
"\n"
" -H/--header <header>\n"
" (HTTP) Extra header to use when getting a web page. You\n"
" may specify any number of extra headers. Note that if\n"
" you should add a custom header that has the same name\n"
" as one of the internal ones curl would use, your exter\n"
" nally set header will be used instead of the internal\n"
" one. This allows you to make even trickier stuff than\n"
" curl would normally do. You should not replace inter\n"
" nally set headers without knowing perfectly well what\n"
" (HTTP) Include the HTTP-header in the output. The HTTP-\n"
" header includes things like server-name, date of the\n"
" document, HTTP-version and more...\n"
" (HTTP/FTP) Fetch the HTTP-header only! HTTP-servers\n"
" feature the command HEAD which this uses to get nothing\n"
" but the header of a document. When used on a FTP file,\n"
" curl displays the file size only.\n"
"\n"
" -K/--config <config file>\n"
" Specify which config file to read curl arguments from.\n"
" The config file is a text file in which command line\n"
" arguments can be written which then will be used as if\n"
" they were written on the actual command line. If the\n"
" first column of a config line is a '#' character, the\n"
" rest of the line will be treated as a comment.\n"
"\n"
" Specify the filename as '-' to make curl read the file\n"
" from stdin.\n"
"\n"
" -l/--list-only\n"
" (FTP) When listing an FTP directory, this switch forces\n"
" a name-only view. Especially useful if you want to\n"
" machine-parse the contents of an FTP directory since\n"
" the normal directory view doesn't use a standard look\n"
" or format.\n"
"\n"
" -L/--location\n"
" (HTTP/HTTPS) If the server reports that the requested\n"
" page has a different location (indicated with the\n"
" header line Location:) this flag will let curl attempt\n"
" to reattempt the get on the new place. If used together\n"
" with -i or -I, headers from all requested pages will be\n"
" shown.\n"
"\n"
" -m/--max-time <seconds>\n"
" Maximum time in seconds that you allow the whole opera\n"
" tion to take. This is useful for preventing your batch\n"
" jobs from hanging for hours due to slow networks or\n"
" links going down. This doesn't work properly in win32\n"
" systems.\n"
" -M/--manual\n"
" Manual. Display the huge help text.\n"
"\n"
" -n/--netrc\n"
" Makes curl scan the .netrc file in the user's home\n"
" directory for login name and password. This is typi\n"
" cally used for ftp on unix. If used with http, curl\n"
" will enable user authentication. See netrc(4) for\n"
" details on the file format. Curl will not complain if\n"
" that file hasn't the right permissions (it should not\n"
" be world nor group readable). The environment variable\n"

" host.domain.com with user name\n"
"\n"
" machine host.domain.com user myself password secret\n"
"\n"
" -o/--output <file>\n"
" Write output to <file> instead of stdout. If you are\n"
" using {} or [] to fetch multiple documents, you can use\n"
" #<num> in the <file> specifier. That variable will be\n"
" replaced with the current string for the URL being\n"
" fetched. Like in:\n"
"\n"
" curl http://{one,two}.site.com -o \"file_#1.txt\"\n"
"\n"
" or use several variables like:\n"
"\n"
" curl http://{site,host}.host[1-5].com -o \"#1_#2\"\n"
"\n"
" -O/--remote-name\n"
" Write output to a local file named like the remote file\n"
" we get. (Only the file part of the remote file is used,\n"
" the path is cut off.)\n"
"\n"
" -P/--ftpport <address>\n"
" (FTP) Reverses the initiator/listenor roles when con\n"
" necting with ftp. This switch makes Curl use the PORT\n"
" command instead of PASV. In practice, PORT tells the\n"
" server to connect to the client's specified address and\n"
" port, while PASV asks the server for an ip address and\n"
" port to connect to. <address> should be one of:\n"
" interface - i.e \"eth0\" to specify which interface's IP\n"
" address you want to use (Unix only)\n"
" IP address - i.e \"192.168.10.1\" to specify exact IP\n"
" number\n"

"\n"
" -Q/--quote <comand>\n"
" (FTP) Send an arbitrary command to the remote FTP\n"
" server, by using the QUOTE command of the server. Not\n"
" all servers support this command, and the set of QUOTE\n"
" commands are server specific! Quote commands are sent\n"
" BEFORE the transfer is taking place. To make commands\n"
" take place after a successful transfer, prefix them\n"
" with a dash '-'. You may specify any amount of commands\n"
" to be run before and after the transfer. If the server\n"
" returns failure for one of the commands, the entire\n"
" operation will be aborted.\n"
" (HTTP/FTP) Retrieve a byte range (i.e a partial docu\n"
" ment) from a HTTP/1.1 or FTP server. Ranges can be\n"
" specified in a number of ways.\n"
" 0-499 - specifies the first 500 bytes\n"
" 500-999 - specifies the second 500 bytes\n"
" -500 - specifies the last 500 bytes\n"
" 9500- - specifies the bytes from offset 9500\n"

"\n"
" -S/--show-error\n"
" When used with -s it makes curl show error message if\n"
" it fails.\n"
"\n"
" -t/--upload\n"
" Transfer the stdin data to the specified file. Curl\n"
" will read everything from stdin until EOF and store\n"
" with the supplied name. If this is used on a http(s)\n"
" server, the PUT command will be used.\n"
"\n"
" -T/--upload-file <file>\n"
" Like -t, but this transfers the specified local file.\n"
" If there is no file part in the specified URL, Curl\n"
" will append the local file name. NOTE that you must use\n"
" a trailing / on the last directory to really prove to\n"
" Curl that there is no file name or curl will think that\n"
" your last directory name is the remote file name to\n"
" use. That will most likely cause the upload operation\n"
" to fail. If this is used on a http(s) server, the PUT\n"

"\n"
" Get the main page from netscape's web-server:\n"
"\n"

" curl dict://dict.org/m:curl\n"
"\n"
"DOWNLOAD TO A FILE\n"
"\n"
" Get a web page and store in a local file:\n"
"\n"
" curl -o thatpage.html http://www.netscape.com/\n"
"\n"
" Get a web page and store in a local file, make the local file get the name\n"
" of the remote document (if no file name part is specified in the URL, this\n"
" will fail):\n"
"\n"
" curl -O http://www.netscape.com/index.html\n"
"\n"
"USING PASSWORDS\n"
"\n"
" FTP\n"
"\n"
" To ftp files using name+passwd, include them in the URL like:\n"
"\n"
" curl ftp://name:passwd@machine.domain:port/full/path/to/file\n"
"\n"
" or specify them with the -u flag like\n"
"\n"
" curl -u name:passwd ftp://machine.domain:port/full/path/to/file\n"
"\n"
" HTTP\n"
"\n"
" The HTTP URL doesn't support user and password in the URL string. Curl\n"
" does support that anyway to provide a ftp-style interface and thus you can\n"
" pick a file like:\n"
"\n"
" curl http://name:passwd@machine.domain/full/path/to/file\n"
"\n"
" or specify user and password separately like in\n"
"\n"
" curl -u name:passwd http://machine.domain/full/path/to/file\n"
"\n"
" NOTE! Since HTTP URLs don't support user and password, you can't use that\n"
" style when using Curl via a proxy. You _must_ use the -u style fetch\n"
" during such circumstances.\n"
"\n"
" HTTPS\n"
"\n"
" Probably most commonly used with private certificates, as explained below.\n"
"\n"
" GOPHER\n"
"\n"
" Curl features no password support for gopher.\n"
"\n"
"PROXY\n"
"\n"
" Get an ftp file using a proxy named my-proxy that uses port 888:\n"
"\n"
" curl -x my-proxy:888 ftp://ftp.leachsite.com/README\n"
"\n"
" Get a file from a HTTP server that requires user and password, using the\n"
" same proxy as above:\n"
"\n"
" curl -u user:passwd -x my-proxy:888 http://www.get.this/\n"
"\n"
" Some proxies require special authentication. Specify by using -U as above:\n"
"\n"
" curl -U user:passwd -x my-proxy:888 http://www.get.this/\n"
"\n"
" See also the environment variables Curl support that offer further proxy\n"
" control.\n"
"\n"
"RANGES\n"
"\n"
" With HTTP 1.1 byte-ranges were introduced. Using this, a client can request\n"
" to get only one or more subparts of a specified document. Curl supports\n"
" this with the -r flag.\n"
"\n"
" Get the first 100 bytes of a document:\n"
"\n"
" curl -r 0-99 http://www.get.this/\n"
"\n"
" Get the last 500 bytes of a document:\n"
"\n"
" curl -r -500 http://www.get.this/\n"
"\n"
" Curl also supports simple ranges for FTP files as well. Then you can only\n"
" specify start and stop position.\n"
"\n"
" Get the first 100 bytes of a document using FTP:\n"
"\n"
" curl -r 0-99 ftp://www.get.this/README \n"
"\n"
"UPLOADING\n"
"\n"
" FTP\n"
"\n"
" Upload all data on stdin to a specified ftp site:\n"
"\n"
" curl -t ftp://ftp.upload.com/myfile\n"
"\n"
" Upload data from a specified file, login with user and password:\n"
"\n"
" curl -T uploadfile -u user:passwd ftp://ftp.upload.com/myfile\n"
"\n"
" Upload a local file to the remote site, and use the local file name remote\n"
" too:\n"
" \n"
" curl -T uploadfile -u user:passwd ftp://ftp.upload.com/\n"
"\n"
" NOTE: Curl is not currently supporing ftp upload through a proxy! The reason\n"
" for this is simply that proxies are seldomly configured to allow this and\n"
" that no author has supplied code that makes it possible!\n"
"\n"
" HTTP\n"
"\n"
" Upload all data on stdin to a specified http site:\n"
"\n"
" curl -t http://www.upload.com/myfile\n"
"\n"
" Note that the http server must've been configured to accept PUT before this\n"
" can be done successfully.\n"
"\n"
" For other ways to do http data upload, see the POST section below.\n"
"\n"
"VERBOSE / DEBUG\n"
"\n"
" If curl fails where it isn't supposed to, if the servers don't let you\n"
" in, if you can't understand the responses: use the -v flag to get VERBOSE\n"
" fetching. Curl will output lots of info and all data it sends and\n"
" receives in order to let the user see all client-server interaction.\n"
"\n"
" curl -v ftp://ftp.upload.com/\n"
"\n"
"DETAILED INFORMATION\n"
"\n"
" Different protocols provide different ways of getting detailed information\n"
" about specific files/documents. To get curl to show detailed information\n"
" about a single file, you should use -I/--head option. It displays all\n"
" available info on a single file for HTTP and FTP. The HTTP information is a\n"
" lot more extensive.\n"
"\n"
" For HTTP, you can get the header information (the same as -I would show)\n"
" shown before the data by using -i/--include. Curl understands the\n"
" -D/--dump-header option when getting files from both FTP and HTTP, and it\n"
" will then store the headers in the specified file.\n"
"\n"
" Store the HTTP headers in a separate file:\n"
"\n"
" curl --dump-header headers.txt curl.haxx.nu\n"
"\n"
" Note that headers stored in a separate file can be very useful at a later\n"
" time if you want curl to use cookies sent by the server. More about that in\n"
" the cookies section.\n"
"\n"
"POST (HTTP)\n"
"\n"
" It's easy to post data using curl. This is done using the -d <data>\n"
" option. The post data must be urlencoded.\n"
"\n"
" Post a simple \"name\" and \"phone\" guestbook.\n"
"\n"
" curl -d \"name=Rafael%20Sagula&phone=3320780\" \\\n"
" http://www.where.com/guest.cgi\n"
"\n"
" While -d uses the application/x-www-form-urlencoded mime-type, generally\n"
" understood by CGI's and similar, curl also supports the more capable\n"
" multipart/form-data type. This latter type supports things like file upload.\n"
"\n"
" -F accepts parameters like -F \"name=contents\". If you want the contents to\n"
" be read from a file, use <@filename> as contents. When specifying a file,\n"
" you can also specify which content type the file is, by appending\n"
" ';type=<mime type>' to the file name. You can also post contents of several\n"
" files in one field. So that the field name 'coolfiles' can be sent three\n"
" files with different content types in a manner similar to:\n"
"\n"
" curl -F \"coolfiles=@fil1.gif;type=image/gif,fil2.txt,fil3.html\" \\\n"
" http://www.post.com/postit.cgi\n"
"\n"
" If content-type is not specified, curl will try to guess from the extension\n"
" (it only knows a few), or use the previously specified type (from an earlier\n"
" file if several files are specified in a list) or finally using the default\n"
" type 'text/plain'.\n"
"\n"
" Emulate a fill-in form with -F. Let's say you fill in three fields in a\n"
" form. One field is a file name which to post, one field is your name and one\n"
" field is a file description. We want to post the file we have written named\n"
" \"cooltext.txt\". To let curl do the posting of this data instead of your\n"
" favourite browser, you have to check out the HTML of the form page to get to\n"
" know the names of the input fields. In our example, the input field names are\n"
" 'file', 'yourname' and 'filedescription'.\n"
"\n"
" curl -F \"file=@cooltext.txt\" -F \"yourname=Daniel\" \\\n"
" -F \"filedescription=Cool text file with cool text inside\" \\\n"
" http://www.post.com/postit.cgi\n"
"\n"
" So, to send two files in one post you can do it in two ways:\n"
"\n"
" 1. Send multiple files in a single \"field\" with a single field name:\n"
" \n"
" curl -F \"pictures=@dog.gif,cat.gif\" \n"
" \n"
" 2. Send two fields with two field names: \n"
"\n"
" curl -F \"docpicture=@dog.gif\" -F \"catpicture=@cat.gif\" \n"
"\n"
"REFERER\n"
"\n"
" A HTTP request has the option to include information about which address\n"
" that referred to actual page, and curl allows the user to specify that\n"
" referrer to get specified on the command line. It is especially useful to\n"
" fool or trick stupid servers or CGI scripts that rely on that information\n"
" being available or contain certain data.\n"
"\n"
" curl -e www.coolsite.com http://www.showme.com/\n"
"\n"
"USER AGENT\n"
"\n"
" A HTTP request has the option to include information about the browser\n"
" that generated the request. Curl allows it to be specified on the command\n"
" line. It is especially useful to fool or trick stupid servers or CGI\n"
" scripts that only accept certain browsers.\n"
"\n"
" Example:\n"
"\n"
" curl -A 'Mozilla/3.0 (Win95; I)' http://www.nationsbank.com/\n"
"\n"
" Other common strings:\n"
" 'Mozilla/3.0 (Win95; I)' Netscape Version 3 for Windows 95\n"
" 'Mozilla/3.04 (Win95; U)' Netscape Version 3 for Windows 95\n"
" 'Mozilla/2.02 (OS/2; U)' Netscape Version 2 for OS/2\n"
" 'Mozilla/4.04 [en] (X11; U; AIX 4.2; Nav)' NS for AIX\n"
" 'Mozilla/4.05 [en] (X11; U; Linux 2.0.32 i586)' NS for Linux\n"
"\n"
" Note that Internet Explorer tries hard to be compatible in every way:\n"
" 'Mozilla/4.0 (compatible; MSIE 4.01; Windows 95)' MSIE for W95\n"
"\n"
" Mozilla is not the only possible User-Agent name:\n"
" 'Konqueror/1.0' KDE File Manager desktop client\n"
" 'Lynx/2.7.1 libwww-FM/2.14' Lynx command line browser\n"
"\n"
"COOKIES\n"
"\n"
" Cookies are generally used by web servers to keep state information at the\n"
" client's side. The server sets cookies by sending a response line in the\n"
" headers that looks like 'Set-Cookie: <data>' where the data part then\n"
" typically contains a set of NAME=VALUE pairs (separated by semicolons ';'\n"
" like \"NAME1=VALUE1; NAME2=VALUE2;\"). The server can also specify for what\n"
" path the \"cookie\" should be used for (by specifying \"path=value\"), when the\n"
" cookie should expire (\"expire=DATE\"), for what domain to use it\n"
" (\"domain=NAME\") and if it should be used on secure connections only\n"
" (\"secure\").\n"
"\n"
" If you've received a page from a server that contains a header like:\n"
" Set-Cookie: sessionid=boo123; path=\"/foo\";\n"
"\n"
" it means the server wants that first pair passed on when we get anything in\n"
" a path beginning with \"/foo\".\n"
"\n"
" Example, get a page that wants my name passed in a cookie:\n"
"\n"
" curl -b \"name=Daniel\" www.sillypage.com\n"
"\n"
" Curl also has the ability to use previously received cookies in following\n"
" sessions. If you get cookies from a server and store them in a file in a\n"
" manner similar to:\n"
"\n"
" curl --dump-header headers www.example.com\n"
"\n"
" ... you can then in a second connect to that (or another) site, use the\n"
" cookies from the 'headers' file like:\n"
"\n"
" curl -b headers www.example.com\n"
"\n"
" Note that by specifying -b you enable the \"cookie awareness\" and with -L\n"
" you can make curl follow a location: (which often is used in combination\n"
" with cookies). So that if a site sends cookies and a location, you can\n"
" use a non-existing file to trig the cookie awareness like:\n"
"\n"
" curl -L -b empty-file www.example.com\n"
"\n"
" The file to read cookies from must be formatted using plain HTTP headers OR\n"
" as netscape's cookie file. Curl will determine what kind it is based on the\n"
" file contents.\n"

"PROGRESS METER\n"
"\n"
" The progress meter was introduced to better show a user that something\n"
" actually is happening. The different fields in the output have the following\n"
" meaning:\n"
"\n"
" % Received Total Speed Time left Total Curr.Speed\n"
" 13 524140 3841536 4296 0:12:52 0:14:54 292 \n"
"\n"
" From left-to-right:\n"
" - The first column, is the percentage of the file currently transfered.\n"
" - Received means the total number of bytes that has been transfered.\n"
" - Total is the total number of bytes expected to transfer.\n"
" - Speed is average speed in bytes per second for the whole transfer so far.\n"
" - Time left is the estimated time left for this transfer to finnish if the\n"
" current average speed will remain steady.\n"
" - Total is the estimated total transfer time.\n"
" - Curr.Speed is the average transfer speed the last 5 seconds (the first\n"
" 5 seconds of a transfer is based on less time of course.)\n"
"\n"
" NOTE: Much of the output is based on the fact that the size of the transfer\n"
" is known before it takes place. If it isn't, a much less fancy display will\n"
" be used.\n"
"\n"
"SPEED LIMIT\n"
"\n"
" Curl offers the user to set conditions regarding transfer speed that must\n"
" be met to let the transfer keep going. By using the switch -y and -Y you\n"
" can make curl abort transfers if the transfer speed doesn't exceed your\n"
" given lowest limit for a specified time.\n"
"\n"
" To let curl abandon downloading this page if its slower than 3000 bytes per\n"
" second for 1 minute, run:\n"
"\n"
" curl -y 3000 -Y 60 www.far-away-site.com\n"
"\n"
" This can very well be used in combination with the overall time limit, so\n"
" that the above operatioin must be completed in whole within 30 minutes:\n"
"\n"
" curl -m 1800 -y 3000 -Y 60 www.far-away-site.com\n"
"\n"
"CONFIG FILE\n"
"\n"
" Curl automatically tries to read the .curlrc file (or _curlrc file on win32\n"
" systems) from the user's home dir on startup. The config file should be\n"
" made up with normal command line switches. Comments can be used within the\n"
" file. If the first letter on a line is a '#'-letter the rest of the line\n"
" is treated as a comment.\n"
"\n"
" Example, set default time out and proxy in a config file:\n"
"\n"
" # We want a 30 minute timeout:\n"
" -m 1800\n"
" # ... and we use a proxy for all accesses:\n"
" -x proxy.our.domain.com:8080\n"
"\n"
" White spaces ARE significant at the end of lines, but all white spaces\n"
" leading up to the first characters of each line are ignored.\n"
"\n"
" Prevent curl from reading the default file by using -q as the first command\n"
" line parameter, like:\n"
"\n"
" curl -q www.thatsite.com\n"
"\n"
" Force curl to get and display a local help page in case it is invoked\n"
" without URL by making a config file similar to:\n"
"\n"
" # default url to get\n"
" http://help.with.curl.com/curlhelp.html\n"
"\n"
" You can specify another config file to be read by using the -K/--config\n"
" flag. If you set config file name to \"-\" it'll read the config from stdin,\n"
" which can be handy if you want to hide options from being visible in process\n"
" tables etc:\n"
"\n"
" echo \"-u user:passwd\" | curl -K - http://that.secret.site.com\n"
"\n"
"EXTRA HEADERS\n"
