Thank you for your reply. OK, if there would be no better solution, I would go with the first option (to convert PROMPT_COMMAND to PROMPT_COMMANDS and append mine to PROMPT_COMMANDS) and see if something happens. > The problem there is that it interferes with the ability to use > both, as some distros might want as a transition, and result in > commands being executed twice. Now I see the points. I didn't come to the idea to set the values to both as I somehow unconsciously assumed that everyone checks the Bash version when one uses PROMPT_COMMANDS. Thank you for pointing this out. This means that I need to be careful if I would convert PROMPT_COMMAND set by others into PROMPT_COMMANDS. -- Koichi
