For many years, I have had a fancy bash prompt, that contains this:
${PWD/#$HOME/~} This replaces your home dir with a tilde. However, with
bash 3.1, it stopped working:
seg bigtime:/home/seg
$ rpm -q bash
bash-3.1-2
seg bigtime:/home/seg
$ echo ${PWD/#$HOME/~}
/home/seg
It works in bash 3.0 and earlier:
seg hamburger:~
$ rpm -q bash
bash-3.0-31
seg hamburger:~
$ echo ${PWD/#$HOME/~}
~
I was very confused, until I figured out the ~ was now getting expanded
to $HOME, thus $HOME was getting replaced with $HOME! So escaping the
tilde fixes it:
seg bigtime:~
$ echo ${PWD/#$HOME/\~}
~
I don't know if this is a bug or not. And may be too obscure for anyone
to care, but there it is.
