ansistego provides terminal-level steganography for scripts and other ASCII files (ie, protection against 'cat'). It intersperses a text/script with commented ANSI codes that cause most terminals to clear sensitive lines as soon as they are written. Only a specified front text appears. The front text is embedded in the script using ANSI-cloaked comments, so that the text appears unaltered when the script is viewed with cat, but the script can be run without any decoding stage.
MrTools is a suite of tools for managing large, distributed environments. It can be used to execute scripts on multiple remote hosts without prior installation, copy of a file or directory to multiple hosts as efficiently as possible in a relatively secure way, and collect a copy of a file or directory from multiple hosts.
V6 Thompson Shell Port provides two ports of the original /bin/sh from Sixth Edition (V6) UNIX (circa 1975). osh is an enhanced port of the shell, and sh6 is an unenhanced port of the shell. This project also includes glob6, if, goto, and fd2 as external shell utilities. While they remain external for compatible use by sh6, these utilities are integrated into osh to improve shell performance.
Shell Flags (shFlags) is a library written to greatly simplify the handling of command-line flags in Bourne based Unix shell scripts (such as those run with bash, dash, ksh, sh, and zsh). Most shell scripts use getopt for flag processing, but the different versions of getopt on various OSes make writing portable shell scripts difficult. shflags instead provides an API that doesn't change across shell and OS versions, so the script writer can be confident that the script will work.
'pksh' is a hack of the popular 'tcsh' for packets, bytes hosts, and protocols counts. It is a shell, a network sniffer, a query language for network monitoring, and finally a rendering engine to display in a form readable for humans and network administrators all traffic on LAN segments. It aims to give on character-based terminals the same level of information 'ntop' already provides via its embedded Web interface. It does not continuously fill the terminal with packet/byte/protocol information, but allows the user to perform his daily job at the shell level and take a look at network only via a set of commands implemented as extensions to native tcsh built-ins. Output can be filtered/sorted/paged/mailed/etc. using native Unix commands.
