Sometime by mistakes all file permissions get changed and you need to
restore file permission. For example a shell script or some sort of
corruption could change the permissions for packages (installed
files), it may be necessary to reset them.
For example a long time ago my shell script run chmod and chown
commands on /usr and changed the permission. Luckily rpm command can
reset package permission. Sun Solaris pkg command and IBM can also
reset permissions.
Please note that this troubleshooting tip is about resetting the
permission of the installed package files and not about end users
files stored in /home directory.
RPM syntax to fix permission
To set permissions of files in a package, enter:
rpm --setperms {packagename}
RPM syntax to fix file ownership
To set user/group ownership of files in a package, enter:
rpm --setugids {packagename}
List installed package
You can list all installed package with rpm -qa command:
rpm -qa
Output:
basesystem-8.0-5.1.1.el5.centos
glibc-2.5-12
expat-1.95.8-8.2.1

List individual package file permission
You can list individual installed package file permission using
following shell for loop (for example list file permission for zip
package):
for f in $(rpm -ql zip); do ls -l $f; done

Reset the permissions of the all installed RPM packages
You need to use combination of rpm and a shell for loop command as follows:
for p in $(rpm -qa); do rpm --setperms $p; done
for p in $(rpm -qa); do rpm --setugids $p; done
Above command combination will reset all the permissions to the
default permissions under CentOS / RHEL / Fedora Linux.

On SUSE just run:
SuSEconfig --module permissions
To fix most of the permissions if they have changed from default.
