Feature request: bd with no arguments should move up one directory

[mawkler]

I think it would be nice if bd simply corresponds to doing cd .. or bd 1

Not sure I like that idea. It would not be able to print a usage then right? Why not make your own alias alias up='cd ..'?

Right, since you can have a directory named -h it's impossible to implement a help flag. So I see why you're hesitant to implement this. But I feel like the two usages are so easy that they should be self-explanatory. Generally, I feel like a help page isn't super necessary unless you have flags or options.

Justification:

plain cd is equivalent to cd ~. cd has no help accessible from the command line. This feels rather analogous to bd being equivalent to bd 1. It's supposed to save me time, which it does often, but when I'm only moving up one dir I feel like the 1 character difference between bd 1 and cd .. isn't worth the retraining my fingers.

But this is your project, and if you don't feel comfortable with removing the usage, that's okay. I can just fork it, implement it myself, and move on.

Nice comparison @extremepayne. But I think I don't agree on the "cd has a behaviour when passed no arguments" point:

• First, cd is much more known and used, most people who've installed bd have probably forgotten they even have it.
• Second, how do we know the cd authors are happy with that choice or if they keep it that way for backward compatibility?

But, I think it makes sense for you to fork this and make the minor change. You have my blessings. :)

Ok, thanks! I made my own fork now so to anyone who also wants this behaviour my fork is over at Melkster/zsh-bd.
