Changing uid

Ruby
1

Hi all,

I really should know this, but I can’t for the life of me remember how
it goes. I want to change users within a Ruby script on Linux, but
Process::uid= only to takes an integer. What’s the best way to odo the
username => UID lookup?

I wouldn’t bet this is the best way, but it seams to work:

require ‘etc’
puts Etc::getpwnam(‘username’)[:uid]
