This can be a path to a file which contains a single public key in PEM or DER format, or any number of base64 encoded sha256 hashes preceded by ´sha256//´ and separated by ´;´. This option works only if the underlying libcurl is built with TLS-SRP support, which requires OpenSSL or GnuTLS with TLS-SRP support. WARNING: headers set with this option will be set in all requests - even after redirects are followed, like when told with -L, --location. See also --dns-ipv4-addr and --dns-ipv6-addr.

This option overrides -n, --netrc. Use --tls-max if you want to set a maximum TLS version. NOTE that you must use a trailing / on the last directory to really prove to Curl that there is no file name or curl will think that your last directory name is the remote file name to use.

EPRT and LPRT are extensions to the original FTP protocol, and may not work on all servers, but they enable more functionality in a better way than the traditional PORT command. You can thus use --progress-meter to enable the progress meter again. For SSH, if not specified, curl tries the following candidates in order: '~/.ssh/id_rsa', '~/.ssh/id_dsa', './id_rsa', './id_dsa'. When saving output to a file, this option tells curl to store certain file metadata in extended file attributes. Using @- will make curl read the header file from stdin. So you can see, the curl command is a useful utility if you are into downloading stuff through the command line.

"HOST1" and "PORT1" may be the empty string, meaning "any host/port". (TLS) Tells curl to verify the status of the server certificate by using the Certificate Status Request (aka. The list of ciphers suites must specify valid ciphers. Currently, the URL is stored in the xdg.origin.url attribute and, for HTTP, the content type is stored in the mime_type attribute. Certain FTP servers, mainly drftpd, require this non-standard command for directory listings as well as up and downloads in PASV mode. Use --no-styled-output to switch them off. See also --ssl and --ftp-ssl-ccc-mode. The non-RFC behavior is ubiquitous in web browsers, so curl does the conversion by default to maintain consistency.

See also -x, --proxy, --proxy-anyauth and --proxy-digest. To post to this, you enter a curl command line like: ... How to use it, what doesn't work, new features, related tools, questions, news, installations, compilations, running, porting etc. Enables the automatic use of bold font styles when writing HTTP headers to the terminal. Not all FTP servers support the PORT command, try doing a transfer using PASV instead! Added in 7.17.1. curl supports HTTP with numerous options and variations. 1M is 1048576 bytes.
