timedicer-rename-user v1.0 [17 Aug 2023] by Dominic
Description
A simple way to rename or delete a user on a TimeDicer Server. This script is useful if a source machine has been reconfigured so that the default username (%USERNAME%-%USERDOMAIN%) has changed. It requires that [oldname] has a primary group also called [oldname] and a home directory at /home/[oldname], and will refuse to run otherwise.
After a warning prompt, it will rename or delete the user, the group and the user's home directory. Deleting (but not renaming) a user in this way will also irretrievably delete their /home folder - for TimeDicer, this is normally their rdiff-backup archive(s) - you have been warned!
If an Rdiffweb database is found, then sqlite3 is (installed and) used to correct or delete the corresponding entry there.
Usage
sudo ./timedicer-rename-user.sh [options] oldname [newname]
Example
sudo ./timedicer-rename-user.sh frederick-fredspc fred-freds
Options
-h show help and exit
-r only make changes to Rdiffweb database
-x to delete the user
Dependencies
apt-get awk bash deluser find fold grep groupmod sed sqlite3 stty usermod

My Programs
Here is a selection of some (other) programs I have written, most of which run under GNU/Linux from the command line (CLI), are freely available and can be obtained by clicking on the links. Dependencies are shown and while in most cases written and tested on an x86-based Linux server, they should run on a Raspberry Pi, and many can run under Windows using Windows Subsystem for Linux (WSL) or Cygwin. Email me if you have problems or questions, or if you think I could help with a programming requirement.
