I wanted to modify my PS1 to run some commands every time. Let’s say I want it so that if the last executed command was successful, it would add a green smile at the end of PS1, otherwise the smile should be red.
I extracted it to a function:
I’ve seen others add all this information to their PS1 prompt.
I’m new to bash and would like my prompt to show something that in tcsh was trivial, yet after a good google search I still cannot do.
I have a custom PS1 colour where I have the actual shell commands in a distinct colour, just so I can quickly see what commands I typed and separate it from the command output itself.
