Linux – Unix Linux directory compare

directorylinuxunix-shell

I have a known good directory structure that I'd like to compare owner/group and permissions against another server and flag any files/folders that need to be changed. Since I wont have access to both servers at once, I'd like to script out the compare so it churns through the directory and outputs any inaccuracies into a file.

There was a script someone wrote in another question: find / -type d -printf "chmod %m %p \n" > reset_perms.sh that forced the permissions down. I'd like to compare and output the changes rather than force them down.

Can you help?

Instead of printing out the commands to run change permissions, simply adjust the printf to spit out the uid, gid, mode, and fullpath and send the output to a file. Then as womble mentioned, use diff to compare the two files.

$find / -printf "%U, %G, %m, %p\n" > permissions.txt
