4.11 Menu shell script

• Use a text editor to create a menu shell script. The shell script should have 8 options, as listed. Do this using the Bourne shell sh or the bash shell. If you wish you may do one of the scripts in the korn shell, ksh or the tcsh shell.
  • (l) Do a ls for the current directory with the options last specified with loption.
  • (loption) Set the options for the above ls command.
  • (cmd) Run the shell script cmd from a previous lab. See Lab 4.4: Lab Editor 2 -- pico (or vi).
  • (month) Show the current month's calendar. Use the cal command without any arguments for this part.
  • (compile) Compile a "C" program. Do a second keyboard read to get the name of the file to compile. Save this name for future compiles so if your script receives a null input it can compile the "current" file. You may want to consider handling file names both with and without the ".c" ending.
  • (run) Run a.out the last "C" program compiled.
  • (exit) Exit the script.
  • If any other input is received it should be passed to the shell as given.
• After processing one input line request a new input. Use the "simple commands" case and read.
• Test all of the options for your shell script.
• Can you run your script within your script? Write a yes or a no on the printout you turn in for each shell.
