ccp copies stdin or file to stdout, file to file, or files to directory. While copying, it can apply one or several recodings. A recoding maps each byte to one or several (e.g., zero) bytes cdargs CDargs heavily enhances the navigation of the common unix file-system inside the shell. It plugs into the shell built-in cd-command (via a shell function or an alias) and thus adds bookmarks and a browser to it. It enables you to move to a very distant place in the file-system with just a few keystrokes. cdck cdck is a simple program for verifying CD/DVD quality. Even if all files on the disc are readable, some sectors having bad timing and could become unreadable in the future. cdctl a program similar to eject. Like eject, it can eject your CD-ROM/DVD drive, but it does a whole lot more. Eventually, cdctl will provide a user interface to the 2.2 kernel's uniform cdrom driver's ioctl calls. cdif a post-processor of the Unix diff command. It highlights deleted, changed, and added words based on word context, or, optionally, highlights individual changed characters cfind cfind (Content FINDer) is a UNIX tool that provides functionality similar to that of Google Desktop from the command line. cfv a utility to both test and create .sfv and .csv files. These files are commonly used to ensure the correct retrieval or storage of data Change Suffix Change Suffix is a small console tool to easily change the suffix of files. chsuf changes a given suffix of files and even directories. It also can be used to add a suffix to a list. Check SFV can create simple file verification listings (sfv) and test existing sfv files. It uses the crc32 checksum chkwww a small console application you can use to check which Web server a particular site runs chroot_safe a tool to chroot any dynamically linked application in a safe and sane manner. It is designed to replace chroot and su -c while at the same time addressing some of the major shortcomings of these tools Chrootbin Chrootbin is a tool which will help you make basic a chroot environment. It lets you skip the boring parts of making a chroot from scratch. It also helps you to install any other classic executables like strace or find. cksfv cksfv is a program that can use the .sfv file to verify the downloaded files. Also, it can be used to create new .sfv files. Cocalores a configurable caching logresolver colonify colonify helps you to manage your PATH, MANPATH or any other colon-separated variable. It removes duplicate entries, allows you to remove directories and more. command history a program to show the commands that were run on the current day by one or more users specified on the command line ComScan reads input form a serial port and shows that input as ASCII and hex. It can log the input to files. Includes a serial port C++ object to simplify the use of serial port programming in Linux configprog lets programs have configurable strings in their executables conflict conflict displays conflicting filenames in your execution path. Unlike the csh command which, it displays all of the conflicting (non-alias) executable filenames in your path. Coreutils the basic file, shell and text manipulation utilities of the GNU operating system. These are the core utilities which are expected to exist on every operating system cotty a small command-line utility to manage pseudo-terminals, used by fwprc. It allows users to run processes communicating with each other through their tty as opposed to files, pipes, or sockets cpre a supplement to the usual cp that copies groups of files based on a regular expression given at the command line. Written in Haskell cpShuffleSature randomly copies files from one directory to another. It is designed for copying music, pictures, or films onto any hardware device (player) which serves as a filesystem CRM a system to examine incoming e-mail, system log streams, data files or other data streams, and to sort, filter, or alter the incoming files or data streams according to whatever the user desires CryoPID CryoPID allows you to capture the state of a running process in Linux and save it to a file. This file can then be used to resume the process later on, either after a reboot or even on another machine. CSed a set of utilities to color output of other processes, e.g. command line utilites or compilers. These programs make output more readable using different color for the significant pieces of the text cstream a general-purpose stream-handling tool like UNIX dd, usually used in commandline-constructed pipes ctail like running tail -f, but can be used on multiple files. It uses the Curses library to split the screen into as many windows as there are files to watch cufps cufps is a very small console program for retrieving CPU usage information from /proc/stat. d command The d command runs a command in the background and redirects its output to a file. The output file is annotated with start and end time, the actual command used, cwd, host name, etc. You can ask the d command to extract the last command from the output file and run it again, you can ask it to append to the file or not, and other goodies. It comes with handy little programs to look at the output, tail it, etc. It is sort of trivial, but has been streamlined over many years. daemonizer daemonizer is a tool that starts a process while detaching it from the terminal. It makes the given process an orphan, closes all files descriptors, and reopens standard input and output to a log file. This allows you to run and program as a daemon. dbm a very simple Perl 5 script which allows you to manipulate/read DBM files from the command line, or using your favourite editor dd_rescue copies data from one file or block device to another. It is intended for error recovery, so, by default, it doesn't abort on errors, and doesn't truncate the output file ded allows you to navigate through multiple file lists or a directory tree, viewing or changing file attributes rapidly. In addition to conventional file information, it operates on the file's RCS or SCCS archives, making it useful for source-control as well as system administration. Curses-based, it runs on UNIX systems Delay counts down the number of seconds specified on its command line. In this way, it's sort of like the standard sleep command, except that it also provides feedback of the time remaining delsafe delsafe is a set of utilities to hopefully allow you to recover recently deleted files. Basically, when you delete or in certain cases overwrite a file the original file is moved into a trash can. It does this by overriding the original unlink, rename, open, and fopen library calls using the Linux LD_PRELOAD mechanism. Trash cans are placed on top of each mount point and are accessible by each user directly or through links placed in the user's home directory. This makes deletion very fast because, in fact, it is only a renaming. To each filename in the trash can is appended a time/version stamp. dffutils a collection of small tools including diff, cmp, diff3 and sdiff di a disk information utility, displaying everything (and more) that your 'df' command does. It features the ability to display your disk usage in whatever format you desire/prefer/are used to. It is designed to be portable across many platforms Dialog Dialog is a utility to create nice user interfaces to shell scripts, or other scripting languages, such as perl. It is non-graphical (it uses curses) so it can be run in the console or an xterm. Directory Manager Directory Manager (dm) is a small tool for managing often-visited directories using a shell like bash. dirtree a tool for displaying directories. It supports an easier interface than du for combining directory trees and shell scripts dl dl is a perl script which provides a quick solution to the difficulty of recovering deleted files on most UNIX filesystems. Files given to dl are compressed, moved to a private backup directory, and deleted only when they haven't been recovered after a configurable amount of time. dnotify dnotify is a simple program that makes it possible to execute a command every time the contents of a specific directory change in linux. It is run from the command line and takes two arguments: one or more directories to monitor and a command to execute whenever a directory has changed. Options control what events to trigger on: when a file was read in the directory, when one was created, deleted and so on. docbook-utils a collection of all the free software tools you need to work on and format DocBook documents. RPMs are provided for those using RedHat Linux; the sourceware are all conveniently available from a single place if you're using some other OS DosUnix provides a selection of features allowing manipulation of text files in a mixed DOS/Windows and Unix environment drm_tools drm_tools contains several small utilities: accudate, execinput, extract, mdump, and msgqueue. accudate is a date replacement with subsecond accuracy. execinput executes commands one at a time from stdin. extract extracts and then emits column/token fields. mdump formats binary data files. msgqueue provides command line control of message queues. DSI utilities The DSI utilities are a mixed collection of classes accumulated during the last ten years in projects developed at the DSI (Dipartimento di Scienze dell'Informazione, i.e., Information Sciences Department) of the Università degli Studi di Milano. dupmerge scans a UNIX directory tree looking for pairs of distinct files with identical content. When it finds such files, it deletes one file to reclaim its disk space and then recreates its path name as a link to the other copy Dupseek Dupseek finds and interactively removes duplicate files. It aims at maximum efficiency by keeping file reads to a minimum and is much better than other similar programs when dealing with groups of large files of the same size.
