Question

I know a few advanced ways, to change directories. pushd and popd (directory stack) or cd - (change to last directory).

But I am looking for quick way to achieve the following:

Say, I am in a rather deep dir:

/this/is/a/very/deep/directory/structure/with\ lot\ of\ nasty/names 

and I want to switch to

/this/is/another/very/deep/directory/structure/with\ lot\ of\ nasty/names 

Is there a cool/quick/geeky way to do it (without the mouse)?

Answer 1

Do you mean that the path names are the same, and only one directory name changes (‘a’ becomes ‘another’)? In that case:

cd ${PWD/a/another} 

will switch to the other directory. $PWD holds your current directory, and ${var/foo/bar} gives you $var with the string ‘foo’ replaced by ‘bar’.
