how to enable username and hostname in the default theme?

[ssbarnea]

I do want to stick with the default theme but I want to just be able to see username and hostname in order to avoid running commands on the wrong host.

How can I do this?

[sounak98]

You'll have to modify the theme settings. Go and open the theme(s) directory and select the theme you want to use. Open it in any of the text editors available. And make the necessary changes.
If you tell me which theme you use particularly I can help you @ssbarnea.

[ssbarnea]

@sounak98 I would like to stick to the default theme because I expect is the most mature one and least likely to have bugs. The only thing that I don't like about it is the missing username and hostname.

I find quite overwhelming the number of themes and the fact that there is no matrix like comparison between them makes any decision even harder.

I guess that less-is-more concept does not apply to oh-my-zsh themes ;)

[sounak98]

Sorry for the late reply. Did you get it already? If not I'll tell you the way to do it. @ssbarnea

[sounak98]

PROMPT='%(!.%{%F{yellow}%}.)$USER @ %{$fg[white]%}%M %{$fg_bold[red]%}➜ %{$fg_bold[green]%}%p %{$fg[cyan]%}%c %{$fg_bold[blue]%}$(git_prompt_info)%{$fg_bold[blue]%} % %{$reset_color%}'

[sounak98]

Change the value of PROMPT to this in the file /themes/robbyrussell.zsh-theme

[mcornella]

Copy the robbyrussell.zsh-theme to $ZSH_CUSTOM/themes/robbyrussell.zsh-theme. Then edit the $PROMPT as in #5686 (comment).

More info about customization.

Am I wrong or all these solutions to break the ability to get updates of oh-my-zsh? If I clone it means that I am stuck on that specific version.

Maybe unrelated to this ticket but I found quite weird not to be able to compare themes by their features like:

• display error code of last command
• single line / multiple lines
• display username
• display group
• distinguish between root and non root users
• display current time
• display git branch
• included in core

My impression is that could be achieved by creating a google spreadsheet with main features as columns and themes as rows, allowing us to filter the themes with an auto-filter.

[ssbarnea]

@sounak98 it seems that your example alternative prompt value contains at least one important bug: the prompt arrow is always red but on original default theme the colour is based on the result of the last command (green = success, red means != 0 return code).

Ideally the user/hostname should be just a parameter to configure on ~/.zshrc file.

[ssbarnea]

In fact I finally found the solution for the problem, quite surprise how easy it was:

Edit ~/.zshrc file and add this to the end of the file:

PROMPT="$fg[cyan]%}$USER@%{$fg[blue]%}%m ${PROMPT}"

This will add a user@host prefix before the default prompt from the theme, so it will inherit the theme custom prompt without overriding it.

The only thing I was not able to do was to find out how to produce the dark-grey colour so I ended up using cyan and blue colours. The default colour is too bright and I don't want to be distracted by something too shiny.

[sounak98]

Yeah @ssbarnea it's true that you won't be able to update after this. Yours is a better method in that sense. Cheers. 😄

[ssbarnea]

@sounak98 It seems that this bug should be reopened because I found a serious bug related to the workaround.

PROMPT="$fg[cyan]%}$USER@%{$fg[blue]%}%m ${PROMPT}"

If you add this to .zshrc, it will give you the impression that it works but it breaks the auto-completer in a very ugly way. You need to test it yourself to see it as it seems quite hard to explain.

• Enable the PATH alternation
• start a new shell
• run a command like curl -V
• now type cu<tab>
• you will observed that the completion happens at the wrong position and you end-up with a messed/confusing command line prompt.

[ssbarnea]

I still don't consider this issue as resolved as long we do not have an option to deploy/install oh-my-zsh using a one-liner and end-up with the hostname in prompt. No further changes.

Not having the hostname as part of the prompt is recipe for disasters.

Did anyone create a way to compare themes based on features?

Hi.

You can create under the ~/.oh-my-zsh/custom a new folder named themes.

Copy the base theme you want to add the user@host from the ~/.oh-my-zsh/themes to: ~/.oh-my-zsh/custom/themes/mycustomtheme.zsh-theme (you can change mycustomtheme to whatever you want).

Then add the PROMPT="$fg[cyan]%}$USER@%{$fg[blue]%}%m ${PROMPT}" line into your theme file.

Finally edit the ~/.zshrc and change ZSH_THEME="mycustomtheme".

It works fine in this way and you can update without problems since the custom folder is in the .gitignore file.

[jontro]

It would be nice if this could be a configurable in the default theme. Copying the theme and modifying it seems like an awkward work around

[cduque89]

When you copy the theme to your custom folder you are creating your own theme, but instead of making it from scratch you started with a base. For me is a good solution. What I do is put all my custom settings in the custom folder, doesn't matter if it is a change to the theme, to the PATH variable, an alias, etc..

In this way I sync my custom folder to my own git repository and when I change machines I only need to pull my custom settings and everything is with the same configuration. For example my personal laptop with Xubuntu and my work Mac Book have the same custom settings and when I need to add any new settings it will be synced on both machines.

Of course you can also have some settings only in one of the machines it is all a question of your personal custom configuration.

Hello,

i came across the same auto-complete problem when i tried the solution proposed by @ssbarnea. But it appears to me that this behavior is due to a missing opening-bracket in the line that was added to .zshrc.
I tried to fix this by altering that line:

PROMPT="%{$fg[white]%}%n@%{$fg[green]%}%m%{$reset_color%} ${PROMPT}"

This gives me the user@host in front of the prompt and the auto-complete feature seems to be working fine.

[Shea690901]

Would´nt it be possible to use zstyle to switch on/off what´s displayed within the prompt?
That way one wouödn´t need to change a theme but just set the corresponding styles...

[ssbarnea]

Can we please reopen this? I want to deploy ohmyzsh to all hosts for root account too and I am pretty people will scream only because of this: where is my hostname/username, nothing else.

If we need to customize things to enable these it means that we degrade the user experience (UX) because the best user experience is that that does just-works and that does not require "investigation". Especially for system where management is shared this matters.

[Smithx10]

I just took a look at this and added this in my .zshrc

PROMPT='${${PROMPT}:+"%F{9}%n%f%F{7}@%f%F{3}%m%f "}%F{4}${_prompt_sorin_pwd}%(!. %B%F{1}#%f%b.)${editor_info[keymap]}'

It's been working for the passed hour or so.

[dketterer]

%n is the username
%m is the hostname

Hi Guys,

cp robbyrussell.zsh-theme' to $ZSH_CUSTOM/themes/`
and then use this

local ret_status="%(?:%{$fg_bold[green]%}➜ :%{$fg_bold[red]%}➜ )"
PROMPT='${ret_status} %{$fg_bold[magenta]%}%n %{$fg[cyan]%}%~%{$reset_color%} $(git_prompt_info)'

ZSH_THEME_GIT_PROMPT_PREFIX="%{$fg_bold[blue]%}git:(%{$fg[red]%}"
ZSH_THEME_GIT_PROMPT_SUFFIX="%{$reset_color%} "
ZSH_THEME_GIT_PROMPT_DIRTY="%{$fg[blue]%}) %{$fg[yellow]%}✗"
ZSH_THEME_GIT_PROMPT_CLEAN="%{$fg[blue]%})"

this adds the username@servername , and also shows full path or relative path to ~

[seestonebat]

I also wanted the username and machine in my prompt.
I found I had to wrap the first section in %{..%}>
If I did not, I got spaces inserted into my prompt as described here - https://stackoverflow.com/questions/28799198/zsh-inserts-extra-spaces-when-performing-searches-and-completion

So my prompt looks like this -
PROMPT="%{$fg[cyan]%}$USER@%{$fg[blue]%}%m%} ${PROMPT}"

[Avamander]

I'd rather also like auto-updates, yet the ability to display user & machine based on config.

[grissom1]

There's another useful condition
IF [[ -n $SSH_CONNECTION ]]; then
PROMPT="%{$fg[white]%}%n@%{$fg[green]%}%m%{$reset_color%} ${PROMPT}"
fi
If you only want the prompt for SSH session but not local environment.

[mdmmn378]

Just comment out the prompt_context section the .oh-my-zsh/themes/<your_theme>.zsh-theme file

## Main prompt
build_prompt() {
  RETVAL=$?
  prompt_status
  prompt_virtualenv
  prompt_aws
  # prompt_context
  prompt_dir
  prompt_git
  prompt_bzr
  prompt_hg
  prompt_end
}

PROMPT='%{%f%b%k%}$(build_prompt) '

Thank you it works for me

[GithubUser5462]

A quick copy & paste solution if anyone needs it. Adds "user@hostname" at the beginning.

cp "$ZSH/themes/robbyrussell.zsh-theme" "$ZSH_CUSTOM/themes/" && \
echo "\n# My config" >> $ZSH_CUSTOM/themes/robbyrussell.zsh-theme && \
echo 'PROMPT="%{$fg[white]%}%n@%{$fg[green]%}%m%{$reset_color%} ${PROMPT}"' >> $ZSH_CUSTOM/themes/robbyrussell.zsh-theme && \
echo "\nDone\n";

[Jeinzi]

Unfortunately, none of the suggestions above did what I wanted without bugs. This is my current solution:
PROMPT='%{$fg_bold[white]%}$USER@%{$fg[yellow]%}%m%}%{$fg_bold[cyan]%} %c $(git_prompt_info)%{$reset_color%}'

This looks as follows and, for me, doesn't have any autocompletion bugs:

[jaimey]

This works for me

[mo-cmyk]

can someone help me to also display the device name and not only my name in this custom theme as well?
PROMPT='[%{$fg_bold[white]%}%n%{$reset_color%}@%{$fg_bold[red]%}%{$reset_color%} %{$fg[cyan]%}%c%{$reset_color%} $(git_prompt_info)%{$reset_color%}]$ '

[philipperemy]

Add those lines at the bottom of your .zshrc:

autoload -U colors && colors
PS1="%{$fg[green]%}%n%{$reset_color%}@%{$fg[cyan]%}${${(%):-%m}} %{$fg[yellow]%}%~ %{$reset_color%}%% "

[hnyls2002]

Yeah, I just found when using SSH to connect the remote machine, the username@hostname will always show. To enable this in your shell's prompt, see where your ZSH theme file defines the $PROMPT env variable and delete the condition SSH_TTY; it works!
