Shell Programming and Scripting

test.pl -a1 -b3 -c4

inside test.pl , if I use $0 , it gives me test.pl ..but I am looking for command to get complete program name and arguments passed.

$ cat tester
#!/bin/bash

# scipt name
echo "script name  ${0##*/}"

# all arguments
echo "all arguments $*"

# argument count
echo "argument count $# "

# first argument
echo "First argument $1"

# second argument
echo "second argument $2"

# last argument
last=$#
echo "last argument ${!last}"

$ bash tester 1 2 3 4 

script name  tester
all arguments 1 2 3 4
argument count 4 
First argument 1
second argument 2
last argument 4

$ cat  test.pl
#!/usr/bin/perl
my $c = 1;
 
# script name
my $script = $0;

# count
my $argsc = $#ARGV + 1;
 
print "Total args passed to $script : $argsc \n";
 
# array @ARGV
foreach my $t(@ARGV) {
	print "Arg # $c : $t\n";
	$c++;
}

$ perl test.pl  1 2 3 4
Total args passed to test.pl : 4 
Arg # 1 : 1
Arg # 2 : 2
Arg # 3 : 3
Arg # 4 : 4
