FileExists.sh (GPL)

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.

By the way, you can use this utility to test for files that are not in the current directory. In fact, you can test for files in multiple directories and this utility will return '1' if the file mask is found in any of the specified directories. Following are some examples.

Examples

FileExists.sh "bin/*.java"

FileExists.sh "src/*.class"

FileExists.sh "bin/*.java" "src/*.class"

"-1" is a "ls" flag to display file names in a single column. "2>" redirects stderr; in this case, redirects to /dev/null, which just throws away the stderr output.

Found an incompatibility issue with Ubuntu 12.10. This new attached version below resolves the incompatibility.
