How to create relative path from absolute path in bash?

Question

I am in this directory:

/home/michal/project/test/my-utils/rel/0.1.0

and I would like to get the relative path to /home/michal/project/ in Linux shell:

../../..

I've tried something with sed but I did not succeeded in creating the regular expression. E.g. one of the attempts:

pwd | sed -e "s/.*project\///g" | sed -e "s/[^\/]+/../g"

Any tips how to do it?

You can use the command realpath:

realpath --relative-to=${PWD} /home/michal/project/

from the help page:

--relative-to=FILE print the resolved path relative to FILE
