I like to change the default shell environment on systems that I use to
and theme them a little. This post describes my usual changes.
Here is how to install
zsh on an Ubuntu system,
Next we need to change the default login shell for the current user. Here is the command (this is a bash commmand),
After running the command, you need to log-off and log-in again. Just closing
and re-opening the terminal isn’t enough. If you want to confirm the changes
before logging off, you can visit
/etc/passwd to see the default shell
configured for the different users. I suggest not to edit that file directly.
This could be done automatically, but I feel it gives more control to do it manually. First we need to clone the repository,
Next, to create a new zsh configuration file,
The above command will over-write the existing
.zshrc file. Considering that
this was a clean install, I’m not concerned about making backups.
One of the reasons I like to use zsh - the wonderful theme support. There used to be an older 9k version of this theme which got depreciated. To install this version it is a simple matter of cloning the repo :)
And finally, to set
ZSH_THEME="powerlevel10k/powerlevel10k" in the
After all this is done, opening a new shell will start a configuration utility
for the theme. We can edit
~/.p10k.zsh to customize the theme. Some of the
changes I like to tweak are,
pyenvtakes care of it
- enable 2-line support
- changing the prompt to
$- am just more used to it
nvm need some customizations which I throw into the
~/.zshrc file at this point (after installing oh-my-zsh ).
