This is a quick script I did this morning while waiting for a file to finish uploading. Originally it was a oneliner, but I’ve cleaned it a bit.

The script can also be used to burn an image with cdrecord after it finishes downloading. It should work on bourne and derivatives (ksh, bash, etc…)

#!/bin/sh
if [ $# -ne 2 ] ; then
  echo "Usage: $0 <file> <command>"
  exit
fi

file=$1; cmd=$2 #eg, unzip, "tar -xzf", etc...

i=0;  j=$(du -k $file | cut -f 1)
while [ $i -ne $j ]
do
  echo "Prev: $i Act: $j Cmd: $cmd $file"
  sleep 5
  i=$j
  j=$(du -k $file | cut -f 1)
  if [ $i -eq $j ]
  then
    $cmd $file
  fi
done
