mped-oticon / argv

Print supplied arguments, in gory detail

What?

This script prints all its arguments, in various forms of expansion. All output is printed to stdout, not stderr.

Why?

1. Serve to aid in {debugging, education}.
2. I am tired of seeing various systems printing their arguments but failing to take spacing and quotes into consideration.

Usage example

$ ./argv foo "hello       world" "bar"
Called with 3 arguments, here quoted:
  Argument $1: 'foo'
  Argument $2: 'hello       world'
  Argument $3: 'bar'
------
echo "$0 ${argv[@]@Q}"
++ echo './argv '\''foo'\''' ''\''hello       world'\''' ''\''bar'\'''
./argv 'foo' 'hello       world' 'bar'
------
echo "$0 $@"
++ echo './argv foo' 'hello       world' bar
./argv foo hello       world bar
------
echo "$0 $*"
++ echo './argv foo hello       world bar'
./argv foo hello       world bar
