cd to (or operate on) a file across parallel directories

This is useful for quickly jumping around branches in a file system, or operating on a parellel file.

This is tested in bash. cd to (substitute in PWD, a for b) where PWD is the bash environmental variable for the "working directory"

What others think

Thanks for posting this command. I'm sorry, but I can't understand what it does. Could you share some use cases?

I updated the comment for this.

in bash - PWD is the working directory.

To test -

mkdir -p /tmp/a/b/cow/d

mkdir -p /tmp/a/b/fish/d

cd /tmp/a/b/cow/d; pwd

where are you?

cd ${PWD/cow/fish}; pwd

where are you now?

Comment by greggster 371 weeks and 3 days ago

Thanks! I didn't know about the ${PWD/cow/fish} substitution.

Comment by wpiekutowski 371 weeks ago

Thanks. One of the things I missed way back in the day when I switched from ksh to bash was the ksh "cd a b" which basically does what you show here. I wrote a function so bash does the same thing but this is handy.
