Checking Installed RPM's

Use the rpm -V option to check whether or not a package has been modified.

For example:

rpm -V textutils

If none of the files from the textutils package have changed then rpm will exit without outputting any data. If, on the other hand, the program has changed, you may see something like this:

U.5....T /bin/cat

This isn't as cryptic as it appears. The line returned from rpm -V contains any number of eight characters plus the full path to the file. Here are the characters and their meaning:[1]

S --- File size differs

M --- Mode differs (includes permissions and file type)

5 --- MD5 sum differs

D --- Device major/minor number mis-match

L --- ReadLink(2) path mis-match

U --- User ownership differs

G --- Group ownership differs

T --- mTime differs
