You don’t have a clue dude. What a pitty. First read, then think twice, then post.

There’s PHP which is generally used for web-based applications, but is also a command line language. Perl which can be for web-based CGI’s or command line use, or even graphical environments (eg: using Qt or GTK).

The easiest are shell scripts, using for example the Bash shell, whcih is similar to a batch script, but is a lot more advanced.

If you are familiar with the linux/UNIX command line, and know how to pipe/redirect output you can create some really nice shell scripts.

eg:

#!/usr/local/bin/bash
# above line is path to shell to use, and must be on 1st line

# this script will tell you how many files are in a directory

# set the variable DIR to $1 (which is the 1st command line argument)
DIR=”$1″

# list the directory contents and pipe the output to wc (word count, with option -l to count lines)
# and save to the variable NUMBER, note the backtick (`) character to execute the commands
NUMBER=`ls $1 | wc -l`

# I was taught to use braces ({}) when using multiple variables on a line
echo “There are ${NUMBER} items in ${DIR}”

# otherwise it could just be: echo “There are $NUMBER items in $DIR”
