Hi,
zsh has a feature, which I love and use a lot:
cd A B
If you are in a directory
/abcd/efgh/ijk
and want to go to
/abcdefgh/lmn
simply type
cd ijk lmn
. But suppose there are these two directories
/a/b/ThisIsARedicoluousLongDirectoryNameWhichNoPersonWillReallyTypeInTwice
/a/b/ThisIsARedicoluousLongDirectoryNameWhichNoPersonWillReallyTypeInTwice.bak
and you are in the first one and you want to go to the seond one....
do you really need to type in "ThisIsARedicoluousLongDirectoryNameWhichNoPersonWillReallyTypeInTwice"
twice when you want to use this
cd A B
feature (I know of othere ways to easily to this ../<TAB> for
example...but for this I /insist/ :) of using this cd A B feature :)
?
Cheers
Meino

I suppose you meant /abcd*/*efgh/lmn 😏
What cd A B really does is simply replace the first occurance of string A
in $PWD with string B and cd to the result.
/a/b/ThisIsARedicoluousLongDirectoryNameWhichNoPersonWillReallyTypeInTwice
/a/b/ThisIsARedicoluousLongDirectoryNameWhichNoPersonWillReallyTy

I'd simply type *cd $PWD $PWD.bak* in this particular case as that's the
shortest option I can think of.
Regards,
Amir

You don't have to type the whole pth component, just the part you
want to replace:
$ cd e e.bak
(unfortunately the first argument cannot be empty; "cd '' .bak"
does not work (why?)).
Or to get back, even
$ cd .bak ""

That doesn't work for me. - It's also one directory, not the two that
I think is needed to move laterally.
Did you by chance mean the following:
cd $PWD{,.bak}
Which expands to two directories, the first with no suffix and the
second with the .bak suffix?

can you elaborate how? it surely should:
$ mkdir omg omg.wtf
$ cd omg
$ pwd
/home/roman/omg
$ cd $PWD.wtf
$ pwd
/home/roman/omg.wtf

`cd foo bar` does not "move laterally", it's like `cd ${PWD:s#foo#bar}`,
except `foo` is not treated as a glob. this doesn't look lateral to me:
$ mkdir x
$ cd x
$ pwd
/home/roman/x
$ mkdir -p .$PWD
$ cd / ./
$ pwd
/home/roman/x/home/roman/x

no, i meant what i wrote: since the second directory differs from $PWD
only in the ".bak" suffix, `cd $PWD.bak` will have the desired effect.

That works for me at home.
I'm guessing that I used "omg.wtf" instead of "$PWD.wtf". Which leads
me to think that this is something special that acts on the PWD
environment variable.
Or there's some sort of environment variable permutation that I'm not
aware of. Which is completely possible.

Okay, I see what you're saying.
% cd /dev/shm
% mkdir omg omg.wtf
% cd omg
% pwd
/dev/shm/omg
% cd omg omg.wtf
% pwd
/dev/shm/omg.wtf
That's why I was saying laterally.

Fair.
Thank you for the explanation Roman.

No, there's nothing special here. The value of $PWD is a full path, to
which you are appending ".wtf".
} % pwd
} /dev/shm/omg
} % cd omg omg.wtf
} % pwd
} /dev/shm/omg.wtf
}

Yes, but you could also do "cd dev/shm tmp" and it would try to change
to /tmp/omg. It's only "lateral" because you happen to be using a
string that matches only the tail of the path.

*facePalm*
I completely missed that simple low hanging fruit.
I'm done for the day.
/me turns and hollers "Check please."

Thank you for trying to explain this. My brain is not accepting it.
I'll get some sleep and (re)read some manuals to try to pick up what I'm
missing or have forgotten.
