docs/cmdline-opts/quote.md
--quoteSend an arbitrary command to the remote FTP or SFTP server. Quote commands are sent BEFORE the transfer takes place (immediately after the initial PWD command in an FTP transfer, to be exact). To make commands take place after a successful transfer, prefix them with a dash '-'.
(FTP only) To make commands be sent after curl has changed the working directory, immediately before the file transfer command(s), prefix the command with a '+'.
You may specify any number of commands.
By default curl stops at first failure. To make curl continue even if the command fails, prefix the command with an asterisk (*). Otherwise, if the server returns failure for one of the commands, the entire operation is aborted.
You must send syntactically correct FTP commands as RFC 959 defines to FTP servers, or one of the commands listed below to SFTP servers.
SFTP is a binary protocol. Unlike for FTP, curl interprets SFTP quote commands itself before sending them to the server. Filenames must be provided within double quotes to embed spaces, backslashes, quotes or double quotes. Within double quotes the following escape sequences are available for that purpose: \, ", and '.
Following is the list of all supported SFTP quote commands:
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)
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.
The chmod command modifies the file mode bits of the specified file. The mode operand is an octal integer mode number.
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.
The ln and symlink commands create a symbolic link at the target_file location pointing to the source_file location.
The mkdir command creates the directory named by the directory_name operand.
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)
The pwd command returns the absolute path name of the current working directory.
The rename command renames the file or directory named by the source operand to the destination path named by the target operand.
The rm command removes the file specified by the file operand.
The rmdir command removes the directory entry specified by the directory operand, provided it is empty.
See ln.
