Your syntax is correct (at least for bash; I don't know about other shells), but it seems likely that $PS1 is being reset by bash's reading of its initialization files. Try with --norc as well. See bash(1) for details. Note that this will likely also have other consequences. -- Michael Kjörling 🔗 https://michael.kjorling.se “Remember when, on the Internet, nobody cared that you were a dog?”
