CURLOPT_QUOTE(3)

NAME
CURLOPT_QUOTE - (S)FTP commands to run before transfer

SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_QUOTE,
                          struct curl_slist *cmds);

DESCRIPTION
Pass a pointer to a linked list of FTP or SFTP commands to pass to the server prior to your request. This is 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 stops at first failure. The set of valid FTP commands depends on the server (see RFC 959 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 does 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.

DEFAULT
NULL

PROTOCOLS
SFTP and FTP

EXAMPLE
struct curl_slist *cmdlist = NULL;
cmdlist = curl_slist_append(cmdlist, "RNFR source-name");
cmdlist = curl_slist_append(cmdlist, "RNTO new-name");
curl = curl_easy_init();
if(curl) {
  curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/foo.bin");
  /* pass in the FTP commands to run before the transfer */
  curl_easy_setopt(curl, CURLOPT_QUOTE, cmdlist);
  ret = curl_easy_perform(curl);
  curl_easy_cleanup(curl);
}

AVAILABILITY
SFTP support added in 7.16.3. *-prefix for SFTP added in 7.24.0
