hi i need a script for - a utility script named "fileowner." This script
should take a filename as an argument and output the file owner's
username, userid (uid), and regular name. If the user does not supply
a filename, the script should report a usage error and exit. If the
user gives a file that does not exist, the script report that the file
does not exist and exit.

Here are some sample runs of the fileowner script:

/home/jsmith fileowner foo
jsmith
7503
John Smith
java script:emoticon(':(')
