CURLOPT_QUOTE - (S)FTP commands to run before transfer
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_QUOTE,
struct curl_slist *cmds);
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
curl_slist_append(3) to append strings (commands) to the list, and
clear the entire list afterwards with
curl_slist_free_all(3).
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:
- 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 curl_getdate(3) man page for date expression
details. (Added in 7.73.0)
- 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.
- chmod mode file
- The chmod command modifies the file mode bits of the
specified file. The mode operand is an octal integer mode number.
- 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.
- 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.
- mkdir directory_name
- The mkdir command creates the directory named by the
directory_name operand.
- 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 curl_getdate(3) man page for date
expression details. (Added in 7.73.0)
- pwd
- The pwd command returns the absolute path of the
current working directory.
- 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.
- rm file
- The rm command removes the file specified by the file
operand.
- rmdir directory
- The rmdir command removes the directory entry specified by
the directory operand, provided it is empty.
- statvfs file
- The statvfs command returns statistics on the file system
in which specified file resides. (Added in 7.49.0)
- symlink source_file target_file
- See ln.
