Ubuntu Manpage: CURLOPT_QUOTE - (S)FTP commands to run before transfer

Provided by: libcurl4-doc_8.9.1-2ubuntu2.2_all

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.

DEFAULT

       NULL

PROTOCOLS

       This functionality affects ftp and sftp

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);
         }
       }
