$0 will contain the name of your shell script.
basename is used to strip directory and suffix from filenames
See below for easy understanding:
Code:
 
$$>>cat testers.sh
#!/bin/sh
path="/a/b/c/d/e/f/g.txt"
bn=`basename $path`
echo "basename is $bn and script name is $0"

output is:
Code:
 
$$>>testers.sh
basename is g.txt and script name is testers.sh

Also, normally $0 will contain the name of the script the way it was called, you can strip off the path using basename "$0" to get the name of the script itself.
