Mini-Unix-Shell

A simple Unix shell program that supports job control. To become more familiar with the concepts of process control and signaling.

Files:

• Makefile Compiles your shell program and runs the tests*
• README This file
• tsh.c The shell program that you will write and hand in
• tshref The reference shell binary.

The remaining files are used to test your shell

• sdriver.pl The trace-driven shell driver
• trace*.txt The 15 trace files that control the shell driver
• tshref.out Example output of the reference shell on all 15 traces

Little C programs that are called by the trace files

• myspin.c Takes argument and spins for seconds
• mysplit.c Forks a child that spins for seconds
• mystop.c Spins for seconds and sends SIGTSTP to itself
• myint.c Spins for seconds and sends SIGINT to itself
