So I'm looking for a way to shorten the path in the prompt if it reaches a defined length, such as:

user1@localhost:~/Pictures/awesome_trip/

Would be fine, but if we cd into more sub-directories such as:

user1@localhost:~/Pictures/awesome_trip/first_day/mikes_camera/funny_pics

I would like the prompt to change to

user1@localhost:/.../funny_pics

I know how to change the prompt in the .bashrc

I was wondering if there is a way to make it dynamically such that I can get the current length of the working dir and check the length, and change the prompt. something along the lines of:

CUR_PROMPT=$(pwd); # get the working dir

CUR_PROMPT_LENGTH={#CUR_PROMPT}; # get the length


if[ $CUR_PROMPT_LENGTH -gt 20 ]; then


if prompt is long, render shorter version


PS1='\u@\h:...\w:$';
else


else render long version


PS1='\u@\h:\W:$'

Hopefully there is way to do this, Thank you for your answer.

You can use something like the code below. Just add it to your .bashrc file in your home folder. It will basically make your prompt resemble "user@computername [dir] $" so it might look like telegonicaxx@laptop [shared] $

export PS1="\u@\h [\W] \\$\[$(tput sgr0)\]"

You can generate your own prompt style and colors using the website linked below
