+.SH FILES
+.I ~/.curlrc
+.RS
+Default config file, see --config for details.
+.SH ENVIRONMENT
+The environment variables can be specified in lower case or upper case. The
+lower case version has precedence. http_proxy is an exception as it is only
+available in lower case.
+
+Using an environment variable to set the proxy has the same effect as using
+the --proxy option.
+
+.IP "http_proxy [protocol://]<host>[:port]"
+Sets the proxy server to use for HTTP.
+.IP "HTTPS_PROXY [protocol://]<host>[:port]"
+Sets the proxy server to use for HTTPS.
+.IP "[url-protocol]_PROXY [protocol://]<host>[:port]"
+Sets the proxy server to use for [url-protocol], where the protocol is a
+protocol that curl supports and as specified in a URL. FTP, FTPS, POP3, IMAP,
+SMTP, LDAP, etc.
+.IP "ALL_PROXY [protocol://]<host>[:port]"
+Sets the proxy server to use if no protocol-specific proxy is set.
+.IP "NO_PROXY <comma-separated list of hosts/domains>"
+list of host names that should not go through any proxy. If set to an asterisk
+'*' only, it matches all hosts. Each name in this list is matched as either
+a domain name which contains the hostname, or the hostname itself.
+
+This environment variable disables use of the proxy even when specified with
+the --proxy option. That is
+.B NO_PROXY=direct.example.com curl -x http://proxy.example.com
+.B http://direct.example.com
+accesses the target URL directly, and
+.B NO_PROXY=direct.example.com curl -x http://proxy.example.com
+.B http://somewhere.example.com
+accesses the target URL through the proxy.
+
+The list of host names can also be include numerical IP addresses, and IPv6
+versions should then be given without enclosing brackets.
+
+IPv6 numerical addresses are compared as strings, so they will only match if
+the representations are the same: "::1" is the same as "::0:1" but they do not
+match.
+.IP "APPDATA <dir>"
+On Windows, this variable is used when trying to find the home directory. If
+the primary home variable are all unset.
+.IP "COLUMNS <terminal width>"
+If set, the specified number of characters will be used as the terminal width
+when the alternative progress-bar is shown. If not set, curl will try to
+figure it out using other ways.
+.IP "CURL_CA_BUNDLE <file>"
+If set, will be used as the \fI--cacert\fP value.
+.IP "CURL_HOME <dir>"
+If set, is the first variable curl checks when trying to find its home
+directory. If not set, it continues to check \fBXDG_CONFIG_HOME\fP.
+.IP "CURL_SSL_BACKEND <TLS backend>"
+If curl was built with support for "MultiSSL", meaning that it has built-in
+support for more than one TLS backend, this environment variable can be set to
+the case insensitive name of the particular backend to use when curl is
+invoked. Setting a name that is not a built-in alternative will make curl
+stay with the default.
+
+SSL backend names (case-insensitive): bearssl, gnutls, gskit, mbedtls,
+nss, openssl, rustls, schannel, secure-transport, wolfssl
+.IP "HOME <dir>"
+If set, this is used to find the home directory when that is needed. Like when
+looking for the default .curlrc. \fBCURL_HOME\fP and \fBXDG_CONFIG_HOME\fP
+have preference.
+.IP "QLOGDIR <directory name>"
+If curl was built with HTTP/3 support, setting this environment variable to a
+local directory will make curl produce qlogs in that directory, using file
+names named after the destination connection id (in hex). Do note that these
+files can become rather large. Works with both QUIC backends.
+.IP SHELL
+Used on VMS when trying to detect if using a DCL or a "unix" shell.
+.IP "SSL_CERT_DIR <dir>"
+If set, will be used as the \fI--capath\fP value.
+.IP "SSL_CERT_FILE <path>"
+If set, will be used as the \fI--cacert\fP value.
+.IP "SSLKEYLOGFILE <file name>"
+If you set this environment variable to a file name, curl will store TLS
+secrets from its connections in that file when invoked to enable you to
+analyze the TLS traffic in real time using network analyzing tools such as
+Wireshark. This works with the following TLS backends: OpenSSL, libressl,
+BoringSSL, GnuTLS, NSS and wolfSSL.
+.IP "USERPROFILE <dir>"
+On Windows, this variable is used when trying to find the home directory. If
+the other, primary, variable are all unset. If set, curl will use the path
+"$USERPROFILE\\Application Data".
+.IP "XDG_CONFIG_HOME <dir>"
+If \fBCURL_HOME\fP is not set, this variable is checked when looking for a
+default .curlrc file.
+.SH "PROXY PROTOCOL PREFIXES"
+The proxy string may be specified with a protocol:// prefix to specify
+alternative proxy protocols. (Added in 7.21.7)
+
+If no protocol is specified in the proxy string or if the string does not match
+a supported one, the proxy will be treated as an HTTP proxy.
+
+The supported proxy protocol prefixes are as follows:
+.IP "http://"
+Makes it use it as an HTTP proxy. The default if no scheme prefix is used.
+.IP "https://"
+Makes it treated as an **HTTPS** proxy.
+.IP "socks4://"
+Makes it the equivalent of --socks4
+.IP "socks4a://"
+Makes it the equivalent of --socks4a
+.IP "socks5://"
+Makes it the equivalent of --socks5
+.IP "socks5h://"
+Makes it the equivalent of --socks5-hostname
+.SH EXIT CODES
+There are a bunch of different error codes and their corresponding error
+messages that may appear under error conditions. At the time of this writing,
+the exit codes are:
+.IP 0
+Success. The operation completed successfully according to the instructions.
+.IP 1
+Unsupported protocol. This build of curl has no support for this protocol.
+.IP 2
+Failed to initialize.
+.IP 3
+URL malformed. The syntax was not correct.
+.IP 4
+A feature or option that was needed to perform the desired request was not
+enabled or was explicitly disabled at build-time. To make curl able to do
+this, you probably need another build of libcurl.
+.IP 5
+Could not resolve proxy. The given proxy host could not be resolved.
+.IP 6
+Could not resolve host. The given remote host could not be resolved.
+.IP 7
+Failed to connect to host.
+.IP 8
+Weird server reply. The server sent data curl could not parse.
+.IP 9
+FTP access denied. The server denied login or denied access to the particular
+resource or directory you wanted to reach. Most often you tried to change to a
+directory that does not exist on the server.
+.IP 10
+FTP accept failed. While waiting for the server to connect back when an active
+FTP session is used, an error code was sent over the control connection or
+similar.
+.IP 11
+FTP weird PASS reply. Curl could not parse the reply sent to the PASS request.
+.IP 12
+During an active FTP session while waiting for the server to connect back to
+curl, the timeout expired.
+.IP 13
+FTP weird PASV reply, Curl could not parse the reply sent to the PASV request.
+.IP 14
+FTP weird 227 format. Curl could not parse the 227-line the server sent.
+.IP 15
+FTP cannot use host. Could not resolve the host IP we got in the 227-line.
+.IP 16
+HTTP/2 error. A problem was detected in the HTTP2 framing layer. This is
+somewhat generic and can be one out of several problems, see the error message
+for details.
+.IP 17
+FTP could not set binary. Could not change transfer method to binary.
+.IP 18
+Partial file. Only a part of the file was transferred.
+.IP 19
+FTP could not download/access the given file, the RETR (or similar) command
+failed.
+.IP 21
+FTP quote error. A quote command returned error from the server.
+.IP 22
+HTTP page not retrieved. The requested URL was not found or returned another
+error with the HTTP error code being 400 or above. This return code only
+appears if --fail is used.
+.IP 23
+Write error. Curl could not write data to a local filesystem or similar.
+.IP 25

+uploading.
+.IP 26

+Out of memory. A memory allocation request failed.
+.IP 28
+Operation timeout. The specified time-out period was reached according to the
+conditions.
+.IP 30
+FTP PORT failed. The PORT command failed. Not all FTP servers support the PORT

+Interface error. A specified outgoing interface could not be used.
+.IP 47
+Too many redirects. When following redirects, curl hit the maximum amount.
+.IP 48
+Unknown option specified to libcurl. This indicates that you passed a weird
+option to curl that was passed on to libcurl and rejected. Read up in the
+manual!
+.IP 49
+Malformed telnet option.
