The script name is highest
The first required parameter is "filename" and the filename here is "albums". If no "filename" is provided a message is displayed.
The second parameter is an optional number [how many] meaning how many albums/artist do you want to display (default of 10).
There is also a requirement that if the user uses the -h option, it would create a header "ALBUMS ARTIST" + newline, and if the -h is not used as an option, then no header or new line would exist, but the rest of the script will run. If the user enters a different option such as -a, an invalid option message is displayed. My file "albums" is above, but here is the entire script and also the output with the messages. Note when i run the script without the -h it runs great, minus the header. When run it with -h, i have problems. Thanks again.

script (highest)

Code:

while getopts ":h" opt; do
  case $opt in
    h)
      print -n "ALBUMS ARTIST\n" >&2
      ;;
    \?)
      echo "Invalid option: -$OPTARG" >&2
      ;;
  esac
done

filename=$1
filename=${filename:?"Filename Missing, include the filename after the \"highest\" script as an arguement."}
howmany=$2
sort -nr "$filename" | head -${howmany:=10}

output

Code:

$ highest albums 9
22 Tom Petty
20 Led Zeppelin
18 Stone Temple Pilots
17 Rolling Stones
16 Aerosmith
12 Black Crowes
10 Nirvana
8 Van Halen
5 ACDC
$ 
$ 
$ 
$ 
$ highest -h albums 9
ALBUMS ARTIST
sort: options '-hn' are incompatible
head: invalid option -- 'a'
Try 'head --help' for more information.

SYNOPSIS

       sieveshell --help

DESCRIPTION

       sieveshell allows users to manipulate their scripts on a remote server.	It works via MANAGESIEVE, a work in progress.

       The following commands are recognized:

	   list list scripts on server.

	   put <filename> upload script to server.

	   get <name> [<filename>] get script. if no filename display to stdout

	   delete <name> delete script.

	   activate <name> activate script.

	   deactivate deactivate all scripts.

OPTIONS

       -u user, --user=user
	   The authorization name to request; by default, derived from the authentication credentials.

       -a authname, --authname=authname
	   The user to use for authentication (defaults to current user).

       -r realm, --realm=realm
	   The realm to attempt authentication in.

       -e script, --exec=script
	   Instead of working interactively, run commands from script, and exit when done.
