[NTLUG:Discuss] how do I get a list of files that are set read-only?

[Carl Haddick]

Seems like a nice scripting exercise if you want to automate the
process, but be careful on a live system.

You can find all the readonly files in your 'home' directory, for
example, with this command:

find /home ! -perm +222

You'll need to have read permissions in all the subdirectories for that
to work, so this might be a command to run as root.

Anyway, the first find arg is the path to start the search from, the
bang character (!) indicates a logical not, the -perm is the option to
search based on file permissions, and '+umask' is a mask of bits.
Without the '!', -perm +bits will look for files that have any of the
bits set that are also set in the -perm argument.

With the '!', it will trigger on files that have none of the bits
included in the mask set.  222 is the bits for owner write, group write,
and all the other bozos write.

Did I get that right?

Regards,

Carl
