Re: [LUG] Changing User ID.

[Julian Hall via list <list@xxxxxxxxxxxxx>]

Thanks Michael, unfortunately it didn't work as the laptop already has the same UID.

Cerce ~ # id julian
uid=1000(julian) gid=1000(julian) groups=1000(julian),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),113(lpadmin),130(sambashare)

The output is the same on both machines. I'm at a loss now to understand why it thinks they are different users.

Hi All,

Last weekend the PSU on my main PC died completely so I spent all last
week using my laptop. Not a major problem, except I needed to update a
couple files which raised the issue of permissions. A spreadsheet for
example would only open Read Only or Copy. I would like to use the
same UID on both systems as I am the only person who uses them. I've
read up on changing the UID but you cannot be logged in as the user
you are updating, which is a problem as both systems only have one
user - identical login details. Can I log into the laptop as root to
change the UID on it? Once I know what the desktop uses.

Kind regards,

Julian

If you have a root password, you can indeed log in as root, and use the
'usermod' command to change UID (this will fix all permissions in /home
folders too).

If not, find an install CD or sysrescueCD (on a USB stick works fine)
and chroot into your old system, and you can perform the 'usermod' from
there.

Good luck!

Michael.
