Question

I am new to Unix and looking for some help for my class assignment. The required assignment is as follows:

Write a shell script to locate executable files. This script takes a list of file names from the command line and determines which would be executed had these names been given as commands.

<command> NOT FOUND

<command> would be replaced by the name of the "file" you didn't find.

Examples: The locations of these programs may vary on different systems and the users PATH environment variable.

prompt> mywhich ls
/bin/ls

prompt> mywhich -a cc
/bin/cc
/usr/ucb/cc

prompt> mywhich ./mywhich
./mywhich

prompt> mywhich /bin/ls
/bin/ls

prompt> mywhich fooblar
fooblar not found

prompt> mywhich ksh sh csh bash
/usr/bin/ksh
/bin/sh
/bin/csh
/usr/local/bin/bash
