On the cmsy255 server, write a bash shell script called usrinfo that displays information about a specified user. Make sure the script file is executable. Also make sure that you can run the script without having to specify the directory. For example, you should NOT have to enter ./usrinfo in order for it to run. The script should: • Accept 1 argument from the command line (this is the User ID that you want to display info for) • finger the User ID display any lines from the who command that match this User ID • display any lines from the ps -ef command that match this User ID ● In addition, if the number of arguments is not exactly 1, display an appropriate error message and exit with an exit code of 1.

find The find command takes a pattern as a command-line argument and recur- sively searches through directories to find a filename matching that pattern. It should print a relative path starting with "./" for every file/directory that matches. For example, running ./find 1s.c from within the hw2 directory should print ./1s.c. If run from the parent directory, the output would be . /hw2/1s.c. There may be multiple matches. If we run ./find .c from within the hw2 directory, we should see: ./find.c ./1s.c ./tree.c The output does not need to be sorted. If nothing matches, it shouldn't print anything. Pattern matching should be case sensitive.
