Bash - Need to use exit but then call another function?

Question

I'm writing a little script to use the webcam on the laptop and then email across the photo to me. The ffmpeg usage has to have a exit code for it to work so with this exit the mail function will not get called. What am I doing wrong?

#!/bin/bash

[email protected]
ts=`date +%s`
list=$(ls | tail -n 1)

function mcheese(){
mkdir /tmp/cheese
cd /tmp/cheese
echo -e "Cheese " | mutt -s "$TS Cheese" $MAIL_ADDR -a $list
}

function cheese(){
ffmpeg -f video4linux2 -s vga -i /dev/video0 -vframes 3 /tmp/cheese/vid-$ts.%01d.jpg 
exit 0
}

cheese
mcheese

Answer 1

You setup list in one directory, then change directory and use it. This is unlikely to work.

Use bash -x to work out where your script is actually failing.
