FileExists.sh is a Bourne Shell script that helps you determine whether any file that matches your specified file masks exists. This script will return 1 or 0, which represents true and false respectively. This script returns true when one or more files are found using any of the file masks you specified on the command-line. Using this script, your other scripts can easily determine whether some files exist.
