A shell executable is a program that can be run in a command-line interface (CLI) or terminal. It is typically a binary file that contains compiled code, which the operating system can execute directly.
Key Points:
- Shell: A shell is a command-line interpreter that allows users to interact with the operating system by executing commands.
- Executable: An executable file is a file that can be run as a program. In Unix-like systems, these files usually have specific permissions set to allow execution.
Examples:
- Common shell executables include
/bin/bash,/bin/sh, and/usr/bin/zsh, which are different types of command-line shells.
