Hello :), Recently, I noticed during tests that mkdir -p can handle paths beyond PATH_MAX that is currently 4096. But cd cannot do this. You have to split your cd commands to go to the farthest directory.
I think that cd cannot move if it fails. In case of error, it must keep bash in the same current directory. Maybe I'm wrong. But if I'm wrong and that is not a requirement, then splitting the path before recursive calls of one level depth cd would make cd as resilient as mkdir -p. If I'm not wrong, we need to handle some kind of backtracking in cd. I hope this is something that can be done. I will not argue further if it's not accepted here. ***Below greetings is some sample script to demonstrate/reproduce the "bug/more resilient feature request"*** (For reference, here is where this
