Following script is used to print command line argument and will show you how to access them:
$ vi demo
# Script that demos, command line args
echo "Total number of command line argument are $#"
echo "$0 is script name"
echo "$1 is first argument"
echo "$2 is second argument"
echo "All of them are :- $* or $@"
Run it as follows
Set execute permission as follows:
$ chmod 755 demo
Run it & test it as follows:
$ ./demo Hello World
If test successful, copy script to your own bin directory (Install script for private use)
$ cp demo ~/bin
Check whether it is working or not (?)
$ demo Hello World
NOTE: After this, for any script you have to used above command, in sequence, I am not going to show you all of the above command(s) for rest of Tutorial.
