change user name in bash prompt

[ckonn]

Hello,

I would like to ask how could I change the user name in bash prompt?

For example: from 'tom@dell ~ $' to 'dan@dell ~ $'

Thank you in advance

Look in Control Center (Settings) Users and Groups
You can change the name there

Sorry, ths will not work, as it only changes the display name but not the technical user name. There are many things related with this and things are likely to get broken by changing it.

Create a new user account with the changed name, than copy (don't move!) the user data from the old into the new account.

Attention: Don't miss to add the new account into the group sudo, before you you remove the old one, otherwise you will fall in troubles.

Actually you can change it to whatever you want.

Use the following line in your ~/.bashrc

Code: Select all

! [[ ${EUID} == 0 ]] && PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\][dan@\h]\[\033[01;34m\] \w \$\[\033[00m\] ' || \
	PS1='${debian_chroot:+($debian_chroot)}\[\033[01;31m\]\u\[\033[01;34m\] \W \$\[\033[00m\] '

You can copy and paste it in the terminal to test it out

Unfortunately I do not have .bashrc file in my home directory.

Unfortunately I do not have .bashrc file in my home directory.

That is no problem. Paste the command into a new text file and save the file as .bashrc
Log out and back in to see the effect.
