In computing, cut is a command line utility on Unix and Unix-like operating systems which is used to extract sections from each line of input — usually from a file. It is currently part of the GNU coreutils package and the BSD Base System.
The man page for the sed utility, as seen in various Linux distributions. A man page (short for manual page) is a form of software documentation found on Unix and Unix-like operating systems. Topics covered include programs, system libraries, system calls, and sometimes local system details. The local host administrators can create and install ...
This is a list of POSIX (Portable Operating System Interface) commands as specified by IEEE Std 1003.1-2024, which is part of the Single UNIX Specification (SUS). These commands can be found on Unix operating systems and most Unix-like operating systems.
This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
See Template:Man/die.net for an example; see Template:Man/FreeBSD for a demonstration of varying the attribution by manual section. Internals Template:man handles choosing the default source and calling it for URL and attribution; the default source is Template:man/default , which is a template redirect currently to Template:man/SUS .
The sequence diagram of cut and paste operation. Computer-based editing can involve very frequent use of cut-and-paste operations. Most software-suppliers provide several methods for performing such tasks, and this can involve (for example) key combinations, pulldown menus, pop-up menus, or toolbar buttons.
Most Unix tools which are often used to manipulate filenames (for example sed, basename, sort, etc.) are text processing tools. However, Unix path names are not really text. Consider a path name /aaa/bbb/ccc. The /aaa directory and its bbb subdirectory can in general be created by different users with different environments.
nroff (short for "new roff") is a text-formatting program on Unix and Unix-like operating systems. It produces output suitable for simple fixed-width printers and terminal windows. It is an integral part of the Unix help system, being used to format man pages for display. nroff and the related troff were both developed from the original roff.
