php - restore permissions after set by error chmod -R 775 / -


by error set folders , files permissions on 775, executing command

sudo chmod 775 -r /website/folder /

and need restore server folders , paths permissions @ least centos files, moment can't send emails websites...

system centos 5

thanks...

this not meant complete solution, rather idea how solve this.

you query packet database (in centos afair rpm) , set permissions way meant according database.

some helpful commands rpm:

  • rpm -va verifies files registered in rpm database. files have wrong permissions listed there. files wrong mode displayed m in 2nd column. rpm -va | grep ^.m | cut -c 13- should start.

  • another option query files in packets with

    rpm --queryformat='%{filemodes}\t%{filenames}\n' -qa

    and process output piping kind of loop such as

    | while read mode fn; chmod -v ... "$fn"; done

    but here have convert decimal output filemodes octal chmod understands it.

    alternatively, process output else, python script or so, gives finer control on do.
