fastshell is an implementation of unix based os shell. I made this shell for self studying purpose using this excellent tutorial. fastshell is written in c. The code run and tested on OS X.
Compile fastshell with gcc:
gcc fast.c -o fast
- Currently implemented the following internal shell commands: cd, help and exit.
- External commands can also be executed, that thanks to fast_launch method. As part of learning how shell works i used fork() and exec() methodology in order to execute a different processes and wait them to finish.
fastshell has a standard shell routine:
- get user input:
fast_read_line(); - parse user input:
fast_parse_line(line); - execute the command:
fast_execute(args);
