A Colorful Bash Prompt With Command Results Shown as Smileys

If you like to customize your system, one tip is to change the bash prompt. You can add colors, information, date and time, etc.

I found a colorful prompt interesting that also shows a green smiley 😉 if the executed command returned 0 (success) or a red sad face 🙁 if the command returned 1 (failure).

To do this, edit the ~/.bashrc file (create the file if it doesn't exist).

nano ~/.bashrc

Add the following lines to the file:

PS1="\`if [ \$? = 0 ]; then echo -e '\[\e[01;32m\]:)'; else echo -e '\[\e[01;31m\]:('; fi\` \[\e[01;34m\][\[\e[01;32m\]\u@\h \[\e[01;34m\]\w\[\e[01;34m\]] $\[\e[00m\] "

To see the result, run:

source ~/.bashrc

Done! Check out the result:
