os.chown()

[James Colannino]

Hey everyone. I tried to use os.chown() in the following manner:

os.chown('filename', 'username', 'groupname')

I got an error, and when I googled for this function I realized that I
must pass the numerical uid and gid. My question is, is there a way for
me to change ownership based on the name instead of the number? Perhaps
there's a function that will let me lookup the uid from the username,
and the gid from the groupname?

Thanks :)

James

You want pwd.getpwnam and grp.getgrnam.

One way is:
os.system( 'chown username:groupname filename')

Are you doing this as root? The chown function is usually restricted to
root.
