# This is a Unix shell script.
#   $0 [args...]
# Purpose: Count and display each argument to this shell script.
# It also displays the command name, which is often referred to as
# "Argument Zero" ($0) but is never counted as an argument.

# The $0 variable contains the name of this script, sometimes called
# "argument zero".  It is not an argument to the script itself.
# The script name is not counted as an "argument" to the script;
# only arguments 1 and up are counted as arguments to the script.
#
echo "Argument 0 is [$0]"

# Now display all of the command line arguments (if any).
# These are the real arguments to this script.
