Y'know, Having done this in both Perl, and Bash, I'd argue that the Perl solution, while more elegant, and more versatile, is harder to learn from scratch. The directory recursion provided by "for file in `ls foo` ; do" is far easier, IMHO. Though maybe cpan has a module for it that I neglected to grab at the time. Of course, the easier file IO in bash comes at the expense of Regex's. (sed/awk anyone...) Maybe use a perl script for the name mangling, and call it from the bash script? :) anyway, that's my over-valued 2cents. ;) -G Gavin McDonald ------------------------ EVI Logistic Enterprises email: me(at)gavitron(dot)com phone: (604) 313-3845 -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
