matthewplemmons / shell-v2 Goto Github PK

A simple shell application written in C and compiled on Ubuntu 18.04 using GCC version 9.3.

Using Ubuntu 18.04, or 20.04, open a terminal and clone the repo. Navigate to the shell-v2 directory and run make to compile the program. After compilation, just run the hsh executable.

$ git clone https://github.com/MatthewPlemmons/shell-v2.git
$ cd shell-v2
$ make
$ ./hsh

Running hsh will display the command prompt, denoted by >, and from there commands can be entered.

Available built-in commands:

• cd changes the current working directory within the shell.
• env prints out a list of environment variables.
• exit exits the shell.

Additionally, the shell uses execve to execute any program within directories listed by the PATH evnironment variable.
