A Unix shell is a command-line interpreter (or shell) that provides a traditional Unix-like command line user interface.
Contents
Description
Users direct the operation of the computer by entering commands as text for a command line interpreter to execute, or by creating text scripts of one or more such commands.
Users typically interact with a Unix shell using a terminal emulator, however, direct operation via serial hardware connections, or networking session, are common for server systems.
All Unix shells provide:
- Filename wildcarding
- Piping
- Here documents
- Command substitution
- Variable
- Control structures for condition-testing and iteration
