.TH CURLOPT_QUOTE 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_QUOTE \- (S)FTP commands to run before transfer
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_QUOTE, struct curl_slist *cmds);
|
|
.SH DESCRIPTION
|
|
Pass a pointer to a linked list of FTP or SFTP commands to pass to the server
|
|
prior to your request. This will be done before any other commands are issued
|
|
(even before the CWD command for FTP). The linked list should be a fully valid
|
|
list of 'struct curl_slist' structs properly filled in with text strings. Use
|
|
\fIcurl_slist_append(3)\fP to append strings (commands) to the list, and clear
|
|
the entire list afterwards with \fIcurl_slist_free_all(3)\fP.
|
|
|
|
Disable this operation again by setting a NULL to this option.
|
|
|
|
When speaking to an FTP server, prefix the command with an asterisk (*) to
|
|
make libcurl continue even if the command fails as by default libcurl will
|
|
stop at first failure.
|
|
|
|
The set of valid FTP commands depends on the server (see RFC959 for a list of
|
|
mandatory commands).
|
|
|
|
libcurl does not inspect, parse or "understand" the commands passed to the
|
|
server using this option. If you change connection state, working directory or
|
|
similar using quote commands, libcurl will not know about it.
|
|
|
|
The valid SFTP commands are:
|
|
.RS
|
|
.IP "atime date file"
|
|
The atime command sets the last access time of the file named by the file
|
|
operand. The <date expression> can be all sorts of date strings, see the
|
|
\fIcurl_getdate(3)\fP man page for date expression details. (Added in 7.73.0)
|
|
.IP "chgrp group file"
|
|
The chgrp command sets the group ID of the file named by the file operand to
|
|
the group ID specified by the group operand. The group operand is a decimal
|
|
integer group ID.
|
|
.IP "chmod mode file"
|
|
The chmod command modifies the file mode bits of the specified file. The
|
|
mode operand is an octal integer mode number.
|
|
.IP "chown user file"
|
|
The chown command sets the owner of the file named by the file operand to the
|
|
user ID specified by the user operand. The user operand is a decimal
|
|
integer user ID.
|
|
.IP "ln source_file target_file"
|
|
The ln and symlink commands create a symbolic link at the target_file location
|
|
pointing to the source_file location.
|
|
.IP "mkdir directory_name"
|
|
The mkdir command creates the directory named by the directory_name operand.
|
|
.IP "mtime date file"
|
|
The mtime command sets the last modification time of the file named by the
|
|
file operand. The <date expression> can be all sorts of date strings, see the
|
|
\fIcurl_getdate(3)\fP man page for date expression details. (Added in 7.73.0)
|
|
.IP "pwd"
|
|
The pwd command returns the absolute pathname of the current working directory.
|
|
.IP "rename source target"
|
|
The rename command renames the file or directory named by the source
|
|
operand to the destination path named by the target operand.
|
|
.IP "rm file"
|
|
The rm command removes the file specified by the file operand.
|
|
.IP "rmdir directory"
|
|
The rmdir command removes the directory entry specified by the directory
|
|
operand, provided it is empty.
|
|
.IP "statvfs file"
|
|
The statvfs command returns statistics on the file system in which specified
|
|
file resides. (Added in 7.49.0)
|
|
.IP "symlink source_file target_file"
|
|
See ln.
