DEFAULT_USER=tangkai@virtual-machine

Just enter your username, leave out the machine.

Still doesn't work

I had trouble too. Finally got it to work DEFAULT_USERNAME=username
My mistake was I put spaces around the '='. Don't include the machine and don't use quotes around the username

DEFAULT_USER=whoami

There are backticks around the command whoami.

ohmyzsh/ohmyzsh#2033

For me worked with export DEFAULT_USER="username". Its worth mentioning that this didn't work for me with other themes, like pygmalion for example.

Just got it working - this shows no username/computer name in the Terminal at all. Using iTerm2 and zsh.

export DEFAULT_USER='whoami'

(Use ` backticks around whoami)

Adding export DEFAULT_USER=whoami`` in ~/.zshrc did the trick for me.

ugh none of these worked for me, did it just like @ccharlton with export DEFAULT_USER=whoami``

The agnoster.theme has this section

# Context: user@hostname (who am I and where am I)
prompt_context() {
  if [[ "$USER" != "$DEFAULT_USER" || -n "$SSH_CLIENT" ]]; then
    prompt_segment black default "%(!.%{%F{yellow}%}.)$USER@%m"
  fi
}

So you need to export USER=whoami`` in the ~/.zshrc.

Still no luck for me $DEFAULT_USER="username" hides everything from the prompt I still want to display the username

@himynameisbeni modify the following in the agnoster.zsh-theme file:

# Context: user@hostname (who am I and where am I)
prompt_context() {
  if [[ "$USER" != "$DEFAULT_USER" || -n "$SSH_CLIENT" ]]; then
    prompt_segment black default "%(!.%{%F{yellow}%}.)$USER@%m"
  fi
}

to:

# Context: user@hostname (who am I and where am I)
prompt_context() {
  if [[ "$USER" != "$DEFAULT_USER" || -n "$SSH_CLIENT" ]]; then
    prompt_segment black default "%(!.%{%F{yellow}%}.)$USER"
  fi
}

dropping the @%m machine name.

This doesn't work on the pygmalion theme. Does anyone have a work around?

gedit ~/.oh-my-zsh/themes/agnoster.zsh-theme
Find these:

Context: user@hostname (who am I and where am I)

prompt_context() {
if [[ "$USER" != "$DEFAULT_USER" || -n "$SSH_CLIENT" ]]; then
prompt_segment black default "%(!.%{%F{yellow}%}.)$USER@%m"
fi
}
If you want to let her display anything, you should drop the '$USER@%m', also you can use any words to change them.

@ubuntu 14.04 DEFAULT_USER=myusername worked just fine

@ubuntu 14.04 DEFAULT_USER=myusername worked just fine also

I tried a bit and at the end it shows: DEFAULT_USER is case-sensitive

Just 'adben' and 'agnoster' themes support this feature.

Using Mac OS X with iTerm2 and zsh with the agnoster theme, simply using:
export USER=ARBITRARYNAMEHERE
where the arbitrary name is surrounded by back ticks.

I'm using Mac OS X with iTerm2 and ohmyzsh with agnoster theme

USER=``

works for me to hide the username@hostname

Please don't use that workaround (USER=""), it could mess up certain commands or functions. Better use either of these:

DEFAULT_USER=$USER

# or

prompt_context() {}

agnoster wiki section.

try

DEFAULT_USER=`whoami`

Regarding these two comments:
@dnlR

For me worked with export DEFAULT_USER="username". Its worth mentioning that this didn't work for me with other themes, like pygmalion for example.

@rastalamm

This doesn't work on the pygmalion theme. Does anyone have a work around?

I had the same problem and found the below works:

  # Context: user@hostname (who am I and where am I)
  prompt_context() {
    if [[ "$USER" != "$DEFAULT_USER" || -n "$SSH_CLIENT" ]]; then
      base_prompt='%{$fg[magenta]%}%n%{$reset_color%}%{$fg[cyan]%}@%{$reset_color%}%{$fg[yellow]%}%m%{$reset_color%}%{$fg[red]%}:%{$reset_color%}%{$fg[cyan]%}%0~%{$reset_color%}%{$fg[red]%}|%{$reset_color%}'
    fi
  }
  base_prompt='%{$fg[cyan]%}%0~%{$reset_color%}%{$fg[red]%}|%{$reset_color%}'

Drop the above snippet in place of the line below in ~/.oh-my-zsh/themes/pygmalion.zsh-theme:

base_prompt='%{$fg[magenta]%}%n%{$reset_color%}%{$fg[cyan]%}@%{$reset_color%}%{$fg[yellow]%}%m%{$reset_color%}%{$fg[red]%}:%{$reset_color%}%{$fg[cyan]%}%0~%{$reset_color%}%{$fg[red]%}|%{$reset_color%}'

The docs for prompt expansion in zsh as per ohmyzsh/ohmyzsh#5904: http://zsh.sourceforge.net/Doc/Release/Prompt-Expansion.html

try

DEFAULT_USER=`whoami`

It works for me. Thanks @shutterfly

try

DEFAULT_USER=`whoami`

Thanks. It works

ah that's not working for me either (iTerm2 + agnoster)

Please don't use that workaround (USER=""), it could mess up certain commands or functions. Better use either of these:

DEFAULT_USER=$USER

# or

prompt_context() {}

agnoster wiki section.

Thanks! This worked for me. iterm2 + agnoster

According to the Readme you can just remove segments with

export AGNOSTER_PROMPT_SEGMENTS[X]=

I used export AGNOSTER_PROMPT_SEGMENTS[2]= to remove the user

@himynameisbeni modify the following in the agnoster.zsh-theme file:

# Context: user@hostname (who am I and where am I)
prompt_context() {
  if [[ "$USER" != "$DEFAULT_USER" || -n "$SSH_CLIENT" ]]; then
    prompt_segment black default "%(!.%{%F{yellow}%}.)$USER@%m"
  fi
}

to:

# Context: user@hostname (who am I and where am I)
prompt_context() {
  if [[ "$USER" != "$DEFAULT_USER" || -n "$SSH_CLIENT" ]]; then
    prompt_segment black default "%(!.%{%F{yellow}%}.)$USER"
  fi
}

dropping the @%m machine name.

Worked fine for agnoster. I just needed my machine name hence removed $n@ (actually it was not @user). It worked!

try

DEFAULT_USER=`whoami`

Thanks it worked for me.

This worked
