compare bunch of files, one on one, between two Folders

Hi,

Wanted to write one shell script to compare bunch of files, one on one, between two Folders and if the difference found only filename should be written to the log file.

Say for e.g
Folder A Folder B Log File
File A File A File A
File B File B
File C File C File C
: :
: :
File N File N

Please assist.

what have you tried so far and where are you stuck.

i think md5sum in a for loop would be adaquate.

You don't need a script, you need just a command:

Code:

diff -rq dir1/ dir2/

My test and output:

Code:

[root@dev /]# mkdir dir1

[root@dev /]# mkdir dir2

[root@dev /]# touch dir1/this

[root@dev /]# touch dir1/this1

[root@dev /]# touch dir1/this2

[root@dev /]# touch dir2/this

[root@dev /]# touch dir2/this1

[root@dev /]# touch dir2/this2

[root@dev /]# echo BLAH > dir2/this2

[root@dev /]# diff -rq dir1/ dir2/



Files dir1/this2 and dir2/this2 differ
