Test whether a glob has any matches in bash

Question

If I want to check for the existence of a single file, I can test for it using test -e filename or [ -e filename ].

Supposing I have a glob

Answer 1

test -e has the unfortunate caveat that it considers broken symbolic links to not exist. So you may want to check for those, too.

function globexists {
  test -e "$1" -o -L "$1"
}

if globexists glob*; then
    echo found
else
    echo not found
fi
