# NAME
|
|
|
|
CURLOPT_QUOTE - (S)FTP commands to run before transfer
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#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.
