In computing, which is a command for various operating systems used to identify the location of executables. The command is available in Unix and Unix-like systems, the AROS shell, [4] for FreeDOS [5] and for Microsoft Windows. [2] The functionality of the which command is similar to some implementations of the type command.
ldd (List Dynamic Dependencies) is a *nix utility that prints the shared libraries required by each program or shared library specified on the command line. [1] It was developed by Roland McGrath and Ulrich Drepper. [2] If some shared library is missing for any program, that program won't come up.
netsh allows local or remote configuration of network devices, Microsoft Windows; Some usages of network configuration tools also serve to display and diagnose networks, for example: iproute2 (on Linux) ifconfig (on Unix) ipconfig (on Windows) route can display an IP routing table; Main network utilities List of the most useful network commands
Application programs may also implement a command-line interface. For example, in Unix-like systems, the telnet program has a number of commands for controlling a link to a remote computer system. Since the commands to the program are made of the same keystrokes as the data being sent to a remote computer, some means of distinguishing the two ...
A Unix shell is a command-line interpreter or shell that provides a command line user interface for Unix-like operating systems. The shell is both an interactive command language and a scripting language , and is used by the operating system to control the execution of the system using shell scripts .
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.
The test command in Unix evaluates the expression parameter. In most recent shell implementations, it is a shell builtin, even though the external version still exists.In the second form of the command, the [ ] (brackets) must be surrounded by blank spaces (this is because [is a program and POSIX compatible shells require a space between the program name and its arguments).
Bash can execute the vast majority of Bourne shell scripts without modification, with the exception of Bourne shell scripts stumbling into fringe syntax behavior interpreted differently in Bash or attempting to run a system command matching a newer Bash builtin, etc. Bash command syntax includes ideas drawn from the Korn Shell (ksh) and the C ...
