Ubuntu – How to remove computer name from the command line prompt

• Open the file ~/.bashrc (or /etc/bash.bashrc if it should work globally for all users).

• Locate the variable called PS1.

• Simply put an \n at the end of the value of the PS1 variable.

Create a small python script which implements the desired trimming logic.

Example: ~/.short.pwd.py

import os
from socket import gethostname
hostname = gethostname()
username = os.environ['USER']
pwd = os.getcwd()
homedir = os.path.expanduser('~')
pwd = pwd.replace(homedir, '~', 1)
if len(pwd) > 33:
    pwd = pwd[:10]+'...'+pwd[-20:] # first 10 chars+last 20 chars
print '[%s@%s:%s] ' % (username, hostname, pwd)

Now test it, from a terminal:

export PROMPT_COMMAND='PS1="$(python ~/.short.pwd.py)"'

If you are ok with the result just append the command to your ~/.bashrc.
