I commented well on this one. So I don't think much more of an explanation would be needed.

Code:

#!/usr/bin/tclsh

#Grabbing Command Line Arguments TCL

#Back_Track http://www.pro9ramming.com

puts "Number of Arguments $argc" 

# If you program in C this may be familiar

# argc = argument count(number of arguments)

set i 1

#giving out variable(type int) a value

#We are preparing for our foreach loop

puts "Execution Statement: $argv0"

foreach arg $argv {

#For each argument in argv(argument variable)

#In C argv is an array of Strings(an array of Char arrays)

#So for each Argument in this puts the number then the actual

#arguments while incrementing i for good measure

puts "Arguments $i is $arg"

incr i

}

Sample Run:

steven@steven-laptop:~/Desktop$ ./Arg.tcl hello Pro9ramming.com!
Number of Arguments 2
Execution Statement: ./Arg.tcl
Arguments 1 is hello
Arguments 2 is Pro9ramming.com!

If ran as such
tclsh Arg.tcl

It will display the programs name
