These are some of my shell scripts which turned out to be useful. Most of them are for Bourne-compatible shells and have been written and tested on recent FreeBSD systems. Maybe you'll have luck and they will work on your system, as well. ;-)
Copy them into some directory along your $PATH and mark them
executable (chmod 0755 <filename>) in order to make
them work.
See the headers of the respective file for usage and detailed license informations. Most of the following scripts are subject to BSD-style license terms.
