The last subdirectory of $HOME
 
Following this post:
http://www.linuxquestions.org/questi...09#post5569609

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

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 :)
