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 path arguments for FTP or SFTP can use single or double quotes to distinguish a space from being the parameter separator or being a part of the path. e.g. rename with sftp using a quote command like this:

"rename 'test/_upload.txt' 'test/Hello World.txt'"

SFTP commands

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.

EXAMPLE

int main(void)
{


  struct curl_slist *cmdlist = NULL;


  cmdlist = curl_slist_append(cmdlist, "RNFR source-name");


  cmdlist = curl_slist_append(cmdlist, "RNTO new-name");


  CURL *curl = curl_easy_init();


  if(curl) {


    CURLcode res;


    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);


    res = curl_easy_perform(curl);


    curl_easy_cleanup(curl);


  }
}
