Flash is an attempt to create a secure menu-driver shell for UNIX-derived OSes,
while providing user-friendliness and easy configurability. An ideal situation
requiring the use of flash would be a student-run telnet server which needs to:
a) shelter the users from some of the nastinesses of UNIX
b) shelter the system from nasty users
c) provide an easy way to launch applications
d) support multitasking/job control as elegantly as possible
e) support easy-to-get-right configuration by administrators
Iron Bars Shell is a restricted Unix shell. The user can not step out of, nor
access files outside the home directory. It is written in C for Linux. No
libraries used. It is small, fast, secure. Two ascii configuration files for
more control.
lshell lets you restrict a user's shell environment to limited sets of
commands, choose to enable or disable any command over SSH (e.g. SCP,
SFTP, rsync, etc.) log user's commands, implement timing restrictions,
and more.

and handling of FATAL errors
SASH (Stand-Alone SHell)
It is a nice combination of bare-bones shell and a dozen
or so most useful Unix commands.
Shell includes: echo pwd cd mkdir mknod rmdir sync rm chmod
chown chgrp touch mv ln cp cmp more exit
setenv printenv umask kill where
Commands include: dd ed grep gzip ls tar file find mount chattr
SASH is a port from Linux version (David Bell) by Andrzej Bialecki
The .tcshrc project creates a set of configuration scripts for the
TCSH shell. These scripts exploit the most advanced features of tcsh.
The original Steve R. Bourne shell from the 7th edition Unix including
System III, 4.3BSD-Reno, Ultrix 3.1 and ``home made'' fixes and enhancements :
* `--' end of options added (sysIII). `set +x' and such added (sysIII).
`/etc/bsh_profile' (sysIII) and `$HOME/.bsh_profile' (unsw) are
sourced at login time if they exist. Initially, only the `.profile'
located in the current directory was sourced at login time if it
exists. They have been `bsh_' prefixed to avoid conflicts w/ the
standards `profiles' which can contains unsupported expressions
such as shell functions. negation (! or ^) in `[]' added (sysIII).
`${x:-x}' and similar expressions added (sysIII). '<<-' (aka strip
leading tab in here document) added (sysIII). `#' comments are
allowed in shell scripts (sysIII/reno), but not on the command line
(reno) ! `break N' and `continue N' fixed (sysIII/ultrix). `if...
then... [elif... [else...]] fi' fixed (reno). `test' (sysIII) and
`ulimit' (ultrix) builtins added.
* ANSI-fication to permit an almost warning free compilation (home made).
`union trenod' taken from 4.3BSD-Reno. better signal handling and
error recovery (sysIII/reno). better restricted shell (sysIII) and
IFS protection (reno).
* functions aren't supported and command line input is not 8 bit clean.
viewglob is an utility designed to complement the Unix shell in
graphical environments. It has two parts:
1. A tool that sits as a layer between the shell and X terminal,
keeping track of the user's current directory and command line.
2. A graphical display which shows the layouts of directories
referenced on the command line (including pwd).
The display reveals the results of file globs and expansions as they
are typed (hence the name), highlighting selected files and potential
name completions.
It can also be used as a surrogate terminal, where keystrokes typed in
the display are passed to the shell. Files and directories can be
double-clicked to insert their names and/or paths into the terminal.
In the Unix tradition, it works with things already there and fills
a empty niche. When incorporating it into your Unix environment, you
keep your command line shell, your editor, your pager, and access to
all your tools, tricks and know-how. Vshnu can operate as an
optional supplemental visual mode to your command line shell. You
switch between command line and visual mode easily as you wish. Your
interface bandwidth and power for Unix operations is on a higher
plane and life gets sweeter.
busybox is a set of common utilities built as a single
crunched binary, and sometimes stripped down in features
to fit the needs of embedded systems.
