Top Forums Shell Programming and Scripting not waiting...why? Post 302258520 by mainegate on Friday 14th of November 2008 05:40:15 PM

I think it works now but I'm totally confused as to why it is behaving this way. The script below works...or at least once the file has encoded completely the QT movie opens...about 15 seconds or so later. That is weird to me. Another weird thing is before the flv would show up even though the file was not 100%. Now the file does not show up until 15 seconds or so after the file has completed.

Note: Scrutinizer you initially recommended 5 seconds to sleep. I changed it to 15 because QT was opening early like before. When I check the log file it said the two values did equal each other. I assume maybe the file took a 5 seconds break or something so I increased it to 15 and it fixed it.

HTML Code:
#! /bin/sh
exec > /tmp/keith 2>&1
set -x
date

/Applications/Compressor.app/Contents/MacOS/./Compressor \
	-clustername 'This Computer' \
	-batchname 'FLV-480X360' \
	-priority low -jobpath "$1" \
	-settingpath '/Users/keith/Library/Application Support/Compressor/FLV - 480 X 360.setting' \
	-destinationpath "$2" &
wait

if [ $? -eq 0 ]
then

NEW=$(ls -s "$2")
while [ "$NEW" != "$OLD" ]; do
  sleep 15
  OLD=$NEW
  NEW=$(ls -s "$2")
done
	  
if [ "$NEW" == "$OLD" ]
then
open -a /Applications/QuickTime\ Player.app "$2"
fi
