A while ago I was asked to remove some users from a production system. Rather than removing them I commented them out in /etc/passwd
i.e.
Code:
# Scott - removed 16.09.12 - userX:*:12345:45678.....
I also removed a symbolic link in /home to the actual home directory, and renamed the actual home directory to something else (i.e. /app/some/dir/prod/userX_DELETEME).
This was handy because a few days later I was asked to put some of the users back!
It's quite a few users so I thought I would write a script to do it recreate the link and rename the directories.
I've generated code to grab the username from the /etc/password but somehow got "# Scott" instead, and for reasons unbeknown seem to have run chown -R on the directory using "# Scott" as the owner, instead of the username.
I'm not quite sure why I ran chown but I have, and now I have a whole bunch of home directories which, when listed, show the owner as "#Scott -". ls -ln.
