Can a bash script prepopulate the prompt with a command to run when it exits? [duplicate]

Answer 1

Thanks for the help, I figured another way. I change the prompt like [tv10 ~]$

just made a file changetv i put inside

PS1="[$1 \W]\$ "

so I run the file and call it as

. ./changetv tv10

so now I know what window is what. :)
