CS:APP Shell Lab

See shlab.pdf for details of assignment.

PLEASE NOTE: This shell does not search PATH for executables, so the full path of an executable must be use to run anything.

Files:

Makefile: Compiles your shell program and runs the tests
README.md: 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
