safecat
safecat - safely copy stdin to a file
safecat is a program which implements Professor Daniel
Bernstein's maildir algorithm to copy stdin safely to a file in
a specified directory. It can be used to write mail messages to
a qmail-style maildir, or to write data to a "spool" directory
reliably.
Install safecat in Debian
#apt-get install safecat

scponly
scponly - Restricts the commands available
to scp- and sftp-users
"scponly" is an alternative 'shell' (of sorts) for system
administrators who would like to provide access to remote users
to both read and write local files without providing any remote
execution priviledges. Functionally, it is best described as a
wrapper to the mostly trusted suite of ssh applications

scsitools
scsitools - Collection of tools for SCSI hardware management
This package is a collection of tools for manipulating SCSI
hardware:
scsiinfo: displays SCSI drive low-level information and modifies
SCSI
drive settings,
scsidev: makes permanent SCSI LUN -> devicename connections,
scsifmt: low-level SCSI formatter,
sraw: benchmarks raw SCSI I/O rates bypassing the buffer cache,
scsistop: low-level SCSI drive start/stop program,
scsi-spin: program to manually spin up and down a SCSI device.
Be aware that these tools require some knowledge of what are
they doing to be used properly, not causing damage to your
system.
Install scsitools in Debian
#apt-get install scsitools

sdd - File duplication and conversion
tool, similar to 'dd'
sdd is a replacement for the dd program the has a number of
useful changes and features, including:
* Better statistics and timing
* Can seek on input and output
* Fast null input and output
* Better NFS data integrity
* Does not reblock on pipes

sformat
sformat - SCSI disk format and repair tool
Sformat will let you low-level format and repair bad blocks on
SCSI disks. It can help you get data off a failing disk and
often resurrect an apparently-broken drive.
Users of SunOS will recognise the features from Sun's format
command.

sharutils
sharutils - shar, unshar, uuencode,
uudecode
'shar' makes so-called shell archives out of many files,
preparing them for transmission by electronic mail services. `unshar'
helps unpacking shell archives after reception. Other related
utility programs help with other tasks.
`uuencode' prepares a file for transmission over an electronic
channel which ignores or otherwise mangles the eight bit (high
order bit) of bytes. `uudecode' does the converse
transformation.
Install sharutils in Debian
#apt-get install sharutils
shc
shc - Shell script compiler
shc creates a stripped binary executable version of the shell
script specified with -f on the command line.
There is no speed increase from using shc. Its main purpose is
to prevent your shell scripts from being easily modified or
inspected. shc can wrap scripts written for any shell.

vobcopy
vobcopy - A tool to copy DvD VOBs to hard
disk
vobcopy copies DVD .vob files to harddisk and merges them into
file(s) with the name extracted from the DVD. It checks for
enough free space on the destination drive and compares the
copied size to the size on DVD (in case something went wrong
during the copying).
You can also mirror the dvd movie content and copy single
files you specify.

w-bassman
w-bassman - an alternative "w" command
This is a version of the "w" command that might be familiar to
old Slackware users. It formats the output differently, in a way
some consider clearer and easier to read.
Install w-bassman in Debian
#apt-get install w-bassman
This will install w-bassman program now if you want to replace w
command with one of these new commands you need to run the
following command
#update-alternatives --config w
then it will ask you two options like below and you need to
select which one you need to use as default one
There are 2 alternatives which provide `w'.
Selection Alternative
-----------------------------------------------
*+ 1 /usr/bin/w.procps
2 /usr/bin/w.bassman
Press enter to keep the default[*], or type selection number: 2
i have chosen 2 option and from now on i ca use w.bassman
command for w command alternative

wcd
wcd - saves time typing when you want to
change directories
Wcd (Wherever Change Directory) is a program to quickly change
directories. It saves time typing at the keyboard. One needs to
type only a part of a directory name and wcd will jump to it. By
default, wcd searches for a directory with a name that begins
with what has been typed, but the use of wildcards is also fully
supported.

#apt-get install wcd

wiggle
wiggle - a program for applying patches
with conflicting changes
Wiggle is a program for applying patches that 'patch' cannot
apply due to conflicting changes in the original.
Wiggle will always apply all changes in the patch to the
original. If it cannot find a way to cleanly apply a patch, it
inserts it in the original in a manner similar to 'merge', and
report an unresolvable conflict

#apt-get install wiggle

wipe
wipe - Secure file deletion
Recovery of supposedly erased data from magnetic media is easier
than what many people would like to believe. A technique called
Magnetic Force Microscopy (MFM) allows any moderately funded
opponent to recover the last two or three layers of data written
to disk. Wipe repeatedly writes special patterns to the files to
be destroyed, using the fsync() call and/or the O_SYNC bit to
force disk access.

#apt-get install wipe

wmmount
wmmount - miniature mount utility and free
space monitoring tool
wmmount runs in a 64x64 window, displaying the amount of free
space on file systems. Simply by clicking on it you can mount
and unmount file systems. This is especially suitable for
removable disks such as floppies, CD-ROMs, ZIP drives etc.
There's nothing in the program that makes it *require* Window
Maker, i.e. it works great with other window managers. But if
you are looking for seamless integration on your desktop,
wmmount in the Window Maker dock may very well suit your needs.

yard
yard - Perl scripts to build rescue disk(s)
to revive a system
Yard is a suite of Perl scripts for creating custom boot/rescue
disks. Using a compressed filesystem, it can put a standard
kernel image plus about 2.4 meg of utilities on a single floppy.
Yard is also useful for creating self-contained
Linux-on-a-floppy systems. You specify a basic set of files and
utilities for inclusion and Yard handles many of the details.
Features:
- File specs allow absolute and relative filenames, symbolic
links,
file replacements and full shell-style globbing.
- Automatically determines necessary libraries and loaders.
- Allows stripping of binaries and libraries during copying.
- Automatically regenerates ld.so.cache
- Checks for broken symlinks
- Checks /etc/{fstab,inittab,termcap,pam.conf} for common errors
and
inconsistencies.
- Checks user directories and files mentioned in /etc/passwd
- Checks command files (eg, rc.local and .login) and scripts for
missing binaries and command interpreters.
- Automatically performs filesystem compression and copying.
- Can be used with or without LILO.
- Can make single or double disk sets.
- Extensive checking of user choices and execution errors.

zsafe
zsafe - Password manager with encryption
ZSafe is a password manager. Passwords can be stored into user
defined categories. The password file will be encrypted by using
a secure RC2 mechanism.
ZSafe makes a fine standalone application with features such as
import and export, encrypted storage, etc.
But one of the added benefits is that it is built from the same
source code as the ZSafe program for the Sharp Zaurus line of
PDAs. Thus, you can use the same program and work with the same
files on your desktop as you can on your PDA. This program uses
the same on-disk format as the Zaurus version.

#apt-get install zsafe

zoo
zoo - manipulate zoo archives
Zoo is used to create and maintain collections of files in
compressed form. It uses a Lempel-Ziv compression algorithm that
gives space savings in the range of 20% to 80% depending on the
type of file data. Zoo can store and selectively extract
multiple generations of the same file.
This package exists for its historical value. If you are looking
for a compression tool for serious use, check tar and gzip.
