Fish (or friendly interactive shell- stylized in lowercase) is a Unix-like shell with a focus on interactivity and usability. Fish is designed to be feature-rich by default, rather than highly configurable. [5] Fish is considered an exotic shell since it does not adhere to POSIX shell standards, at the discretion of its maintainers. [6]
Fish commands are all defined, shell equivalents may vary. Fish commands always have priority: the server is expected to execute a fish command if it understands it. If it does not, however, it can try to execute a shell command. When there is no special server program, Unix shell ignores the fish command as a comment and executes the ...
There are two approaches to this; the shell can either suggest probable corrections upon command invocation, or this can happen earlier as part of a completion or autosuggestion. The tcsh and zsh shells feature optional spell checking/correction, upon command invocation. Fish does the autocorrection upon completion and autosuggestion.
The Sailfish OS and the Sailfish software development kit (SDK) are based on the Linux kernel and Mer. [10] [11] [12] Sailfish OS includes a multi-tasking graphical shell called "Lipstick" built with Qt by Jolla on top of the Wayland display server protocol. [13]
In the Unix shells ksh, bash, fish and zsh, the disown builtin command is used to remove jobs from the job table, or to mark jobs so that a SIGHUP signal is not sent to them if the parent shell receives it (e.g. if the user logs out).
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.
OpenBSD developers were instrumental in the creation and development of OpenSSH (aka OpenBSD Secure Shell), which is developed in the OpenBSD CVS repositories. OpenBSD Secure Shell is based on the original SSH. [48] It first appeared in OpenBSD 2.6 and is now by far the most popular SSH client and server, available on many operating systems. [49]
