Is there a bash shortcut for traversing similar directory structures?
- by Steve Weet
The Korn shell used to have a very useful option to cd for traversing similar directory structures e.g. given the following directorys
/home/sweet/dev/projects/trunk/projecta/app/models
/home/andy/dev/projects/trunk/projecta/app/models
Then if you were in the /home/sweet.... directory then you could change to the equivalent directory in andy's structure by typing
cd sweet andy
So if ksh saw 2 arguments then it would scan the current directory path for the first value, replace it with the second and cd there. Is anyone aware of similar functionality in bash.
EDIT 1
Following on from Michal's excellent answer I have now created the following bash function called scd (For Sideways cd)
function scd {
cd "${PWD/$1/$2}"
}
EDIT 2
Thanks to @digitalross I can now reproduce the ksh functionality exactly with the code from below (With the addition of a pwd to tell you where you have changed to)
cd () {
if [ "x$2" != x ]; then
builtin cd ${PWD/$1/$2}
pwd
else
builtin cd "$@"
fi
}
