Multiple $PS1s with urxvt and xprop

Recently, I decided to embed terminals in my desktop and preferred that the prompt for them should be different than for a normal terminal window. It took a while but I finally achieved it. Embedding the terminals was easy as explained here:

and as for the different $PS1 prompts, I just modified my .bashrc with the following condition:


winId=$(xprop -id $WINDOWID | grep "URxvtbg")

if [ "$winId" == "" ]
PS1="┌─\[\e[1;36m\][\u@\h]\[\e[m\].:\[\e[0;36m\][$(date +"%d/%m/%y-(%T)")]\[\e[m\]:.\[\e[1;36m\][\w]\[\e[m\]\n└─>>\[\e[1;32m\]$\[\e[m\]] "
PS1='[\u@\h \W]\$ '


Basically, what this does is that it gets the window information from xprop using the $WINDOWID bash variable and looks for the specific name* that was assigned to this terminal. If found, applies a specific $PS1 value and if not, applies the other.

*Refer urxvt's man page for the switch '-name'.
