Clobber

Simple UNIX shell. So named as clobber is a synonym of bash, how funny I know.

Features

• Run any program, support for the same programs as bash using execvp and forking.
• Run programs in the background by appending "&", produces an output when the background job is exited.
• Built-in programs "cd", "help" and "exit".
• When a program is running in the foreground CTRL-C is redirected to close that program, otherwise CTRL-C causes Clobber to exit.
• Non-interactive mode, i.e. running commands from files using "clobber.out < "

Limitations

• No redirection (e.g command1 >> filename).
• No piping from one process to another (e.g command1 | command2).

Usage

Build with gcc.

$ make build

Run in interactive mode.

$ ./clobber.out

Run a script, where SCRIPT_PATH is the path of the script.

$ ./clobber.out < SCRIPT_PATH
