I’m reading and enjoying your book. I’m, of course, mesmerized by coolness and power of Akka, and also by the awesome looking flowcharts. Please, share what is the flowchart tool that you are using.

You can also try z (autojumper) by rupa (github rupa/z)

Using the function below you type ccd e2 e1, and you’re there. Not my own invention as the comments make clear. (I think it’s based on a cd capability native to KSH but not Bash.)

return 1

builtin cd “$newdir”
pwd

echo “bash: my_cd: wrong arg count” 1>&2

I’ve always loved the ability to ‘csd test$’, for example, to switch to the first instance of a test directory root in my recent history.

Hell, I don’t even claim it’s a well written script – it’s not even real Bash, but a KSH/Bash hybrid monster of evolution :)

I will say, however, that ‘ss’ isn’t equivalent to dirs due to the fact that the directory pusher doesn’t push dups and ‘pushd’ requires that the user be smart enough not to push dups… I don’t like having to think about what I’m doing here. I just move around with ‘cd’ as I would normally and let the script do the rest.

ss = dirs, however, your “cds” is more complex, a more elaborated mix of “pushd”, “popd” and “cd ~”
