How to use popd?

How to use popd?

[Jörg Sommer]

Hi,

I've this situation:
% dirs
/usr ~ /tmp ~/Tmp/kernel/linux ~
% pwd
/usr

Now I want to go to /tmp. I thought popd +2 is what I need, but I'm still
in /usr. Only the entry for /tmp is removed.

% popd +2
/usr ~ ~/Tmp/kernel/linux ~
% pwd
/usr

Why doesn't popd change the directory?

Bye, Jörg.

This is documented in the manual.  "popd +2" pulls the second item after
the head from the stack then changes to the new top.  The new top is still
/usr.

If you are trying to remove /usr and ~ from the stack completely
use "repeat 2 popd".  If you do this a lot, try

  rpopd() { repeat $1 popd; }

If you're just trying to bring /tmp to the head you need "pushd +2".
