Hence the patch included in my previous email

Thanks for that E. I am glad to have an opportunity to improve my script.
New script attached is now using find instead of ls *
It is also improved in a few other places (spaces in filenames work
okay, error outputs properly suppressed).

#/bin/sh
#Create cinelerra style text file listing image paths for each frame
#this script can be called standalone or from within the animate script
#it takes three parameters: filetype (png or jpg) (default is to try and
determine what file type is in the directory), framerate (default is 12) and
directory to index (default is the directory from which the script is called)
#you probably need to make sure you choose a legitimate cinelerra frame rate
#examples:
#animtext
#(this uses default framerate of 12, does its own checking of the filetype in
the directory, and uses the current directory)
#
#animtext jpg 23.976 animations/sources/1/
#
#animtext jpg 30 /home/gray/animations/sources/2/
