Shell script

Common card · No. 238184

A shell script is a computer program designed to be run by a Unix shell, a command-line interpreter. The various dialects of shell scripts are considered to be command languages. Typical operations performed by shell scripts include file manipulation, program execution, and printing text. A script which sets up the environment, runs the program, and does any necessary cleanup or logging, is called a wrapper. The term is also used more generally to mean the automated mode of running an operating system shell. Different operating systems each use a particular name for these functions. All Unix-like systems include at least one POSIX shell, typically either bash or the zsh compatibility mode.
