Shell

Project carried out as part of Operating Systems class.

The code I wrote is in the files: command.c, jobs.c, shell.c and is marked by the directive #ifdef STUDENT.

detailed description of the task

---

It handles among others job control with the use of the commands:

• fg [n]: changes a stopped or running background job to a foreground job,
• bg [n]: changes the state of the secondary job from stopped to active,
• kill %n: kills the processes belonging to the job with the given number,
• jobs: displays the status of secondary jobs.

Pipes and redirection, e.g:

grep foo test.txt > test.txt | wc -l.
