Following this post:

I want to set PROMPT_COMMAND so the it will contain only the last subdirectory of $HOME.

Right now its:

Code:

PROMPT_COMMAND='printf "\033k%s@%s:%s\033\\" "${USER}" "${PWD/#$HOME/~}"'

I'm looking for some thing like the difference between:

Code:

export PS1="\u@\W>"

Code:

export PS1="\u@\w>"

Thank you

That doesn't seem to be what you're aiming for though. You said that you wanted "to set PROMPT_COMMAND so the it will contain only the last subdirectory of $HOME."

By the way, which shell are you using? Have you looked at basename?

Adding basename

Code:

PROMPT_COMMAND='printf "\033k%s@%s:%s\033\\" "${USER}" `basename "${PWD/#$HOME/~}"`'

Setting the PS1 seems simpler

Code:

unset PROMPT_COMMAND
PS1="\033k\u@\W:\033\\"

Something like this?

Code:

PROMPT_COMMAND='printf "\033k%s@%s:%s\033\\" "${USER}" ${PWD##$HOME*/}'

I think you mean

Code:

PROMPT_COMMAND='printf "\033k%s@%s:%s\033\\" "${USER}" ${PWD##*/}'

I.e. reduce all pathnames, not only the ones that start with the value of $HOME.
But the own homedir is not printed as ~ then.

No I meant to just reduce the ones with $HOME
