Expand glob in variable within shell script

Published on Thu, 24 April 2008

I had the need today to read in a list of patterns from a file, expand them and then operate upon each file all from within a shell script. Apparently there is a shell built-in for csh, but I didn’t want to learn csh at that point. The eventual solution was to run an extra shell with the -c argument.

Example: #!/bin/bash FILES=cat patterns.txt for pattern in $FILES; do bash -c “ls -l ${pattern}” done
