Top Forums Shell Programming and Scripting How to tell UNIX to start from the oldest file? Post 303022464 by jgt on Saturday 1st of September 2018 07:59:42 AM

Code:
if [ -r job.pid ]
then
     exit 1
fi
echo $$ >job.pid

cd /home/tmp

  ls -rt *.txt | while IFS= read -r i 

do     ffmpeg $what_soever_command$     

sleep 5     

mv "$i" "/home/tmp/junkie/$i"
 done
 rm job.pid

Two other considerations:
If the text file is large, then a file may appear in the list while it is being received, and processed while it is still incomplete.
Remove any job.pid files that exist on system boot up.
