how does motion pass an argument to a script in on_picture_save

Question

I made a script to send pictures captured by motion to another machine through ftp. Normally the command line argument is called $1 in the script. When I run the script below from the command line it works. But when this script is called by motion's on_picture_save it doesn't. How should I change the script?

The script looks like this:

#!/bin/bash
ftp www.mysite.com << ftpinput
put $1
ftpinput

Environment

Motion version:	3.2.3
ffmpeg version:
Libraries:	ffmpeg, mysql, postgresql
Server OS:

Which exact version do you run? Is it 3.2.3? Or is it the latest 3.2.4_snap4?

I'm running version 3.2.3-1 from the download page.

Answer

The on_picture_save appends the filename to the command. So in principle the $1 method should work. I cannot say why it does not.

Note that from Motion 3.2.4_snap4 you have to put a %f after the on_picture_save command. This is changed so that you can write more advanced commands where the filename is in the middle of the command. But with 3.2.3 the filename is appended.
