Edit /etc/passwd so that the line which starts with xxxx is changed to
yyyy, do the same with /etc/shadow (I don't recall whether linux has
vipw, if it has use that). Everything except (e) is now done but all is
far from well. You may also like to change the name of his home
directory to /home/yyyy, if you do then you need update /etc/passwd to
reflect this. You also need to check /etc/groups and /etc/aliases. It's
probably worthwhile trying to find any files or directories with xxxx
as a part of their name and last but not least check configuration
files for xxxx. That should fix most of the problems but expect other
things to go wrong. I worked on a project that changed the names of
over 1000 users, I don't know what we would have done without perl to
handle the actual data changes, even so it was a lot of work trying to
find all the important places to change the id.
