Directories Comparison

Objectives

  1. You are given two directories as arguments and the output should be any difference between the two directories

Solution

Suppose the name of the bash script is dirdiff.sh

#!/bin/bash

if test $# -ne 2
then
	echo -e "USAGE: ./dirdiff.sh directory1 directory2"
	exit 1
fi

# check for the checksums. 
# If both the checksums same, then both directories are same
if test `ls -1 $1 | sort | md5sum | awk -F "  " '{print $1}'` == `ls -1 $2 | sort | md5sum | awk -F "  " '{print $1}'`
then
	echo -e "No difference between the 2 directories"
	exit 0
fi

diff -q $1 $2
