backupIT is a script to backup local and remote filesystems onto a remote tape drive. It includes a collection of functions to send mail, to use system commands to drive a tape library, and to use NetBackup(tm) to drive a tape library. backupIT uses rsh/ssh to connect to remote hosts, and it supports ufs, vxfs, and ext2 file systems. It works on Solaris, Slackware Linux, and Red Hat Linux systems. backupIT requires the dump utility, which might not be installed on Linux systems.
The klish is a framework for implementing Cisco-like command-line interfaces on Unix systems. It is configurable through XML files. "Klish" stands for "Kommand Line Interface SHell". The klish is a fork of clish-0.7.3. The original clish was developed by Graeme McKerrell. The klish adds some new features, but is compatible (as much as possible) with clish's XML configuration files.
The FReakSHell aims to be a sh-compatible shell and command language interpreter that has some advanced features that can not be found in other shells. It aims towards POSIX compliance by trying to implement the IEEE POSIX Shell and Tools specification (IEEE Working Group 1003.2). Advanced features include advanced job control (i.e. job exchange between different processes, dynamic repiping) and built-in auto-completion.
