Globbing/pathname expansion with colon as separator
How can I convert a string containing glob characters such as /var/lib/gems/*/bin into a colon-separated string of filenames (i.e. PATH compatible) matching the pattern? i.e. echo /var/lib/gems/*/bin will return /var/lib/gems/1.8/bin /var/lib/gems/1.9.1/bin I want /var/lib/gems/1.8/bin:/var/lib/gems/1.9.1/bin instead. The obvious approach is simply to replace the space character with ':' via tr , but that doesn't work if the filename itself contains the space character. Actually, I thought of a better solution: use a shell function. function join() { local IFS=$1 shift echo "$*" } mystring=$
