NAME

pure-uploadscript - Automatically run an external program after a successful upload

SYNTAX

pure-uploadscript [-p </path/to/pidfile>] [-B] [-g <gid>] [-h] -r <program to run> [-u <uid>]

DESCRIPTION

If Pure-FTPd is compiled with --with-uploadscript (default in binary distributions), and if the -o (or --uploadscript) is passed to the server, a named pipe called /var/run/pure-ftpd.upload.pipe is created. You will also notice an important file called /var/run/pure-ftpd.upload.lock, used for locking.
After a successful upload, the file name is written to the pipe.
pure-uploadscript reads this pipe to automatically run any program or script to process the newly uploaded file.

OPTIONS

Daemonize the process and fork it in background.
Switch the group ID to <gid>.
Display available options.
Tell what program/script to run. It has to be an absolute filename, the PATH environment variable is ignored. The first argument of that program will be the unquoted name of the newly uploaded file. Environment variables aren't cleared. So don't put sensitive data in them before calling pure-uploadscript if you switch uid.
Switch the user ID to <uid>.

ENVIRONMENT

When the upload script is run, the name of the newly uploaded file is the first argument passed to the script (referenced as $1 by most shells) . Some environment variables are also filled by useful info about the file. UPLOAD_SIZE The size of the file, in bytes. UPLOAD_PERMS The permissions, as an octal integer. UPLOAD_UID The numerical UID of the owner. UPLOAD_GID The numerical GID of the owner. UPLOAD_USER The login of the owner. UPLOAD_GROUP The group name the files belongs to. UPLOAD_VUSER The full user name, or the virtual user name (127 chars max) .

FILES

/var/run/pure-ftpd.upload.pipe /var/run/pure-ftpd.upload.lock /var/run/pure-uploadscript.pid

SECURITY

pure-ftpd and pure-uploadscript are trying to limit security implications of such a feature.

EXAMPLES

A sample script could be:

#! /bin/sh
echo "$1 uploaded" | /usr/bin/mutt -s "New upload: $1" \ ftpadmin@dom.ai.n

Never forget to quote ("variable") all variables in all your shell scripts to avoid security flaws.
