Shell Programming and Scripting

Hi All

I am very new to the Unix shell scripting ,, could you pleae help me to generate the output file having the filename and path which files having the difference in the contents in the two directory. all files in both directory have the same name and format.

input directory /edc/input1/ it also can have sub directory
/edc/input2/ it also can have sub directory
output file diffout having path and name fo file.

please let me know if this requremnt are not clear
please provide me some sample script.

thanks

Singh

If I understand correctly, try this

cd /edc/input1 ; find . -type f | sort > /tmp/input1.lst
cd /edc/input2 ; find . -type f | sort > /tmp/input2.lst
diff /tmp/input1.lst /tmp/input2.lst

From the output, lines that begin with a less-than sign '<' exist only in /edc/input1 and those beginning with a greater-than sign '>' exist only in /etc/input2. To see which files exist in BOTH directories, use the join(1) command

join /tmp/input1.lst /tmp/input2.lst

Hi hegemaro

diff /tmp/input1.lst /tmp/input2.lst

is not giving any output. beacuse it is having the same file name in both of the list. i want to print the filename along wiht the path, which having diffrent contents, could u please giv me any idea how can we do this ..
