BASH blank alias to 'cd'

Question

I am a happy BASH user. I do not want to switch to another shell (in this case ZSH).

ZSH has this ability to change a directory without necessarily typing:

cd /to/a/directory

What would be the correct alias (or maybe BASH function) to change directories without having to type cd?

On my above example, moving to /to/a/directory would be done like this:

/to/a/directory

I have tried:

alias ''='cd '
alias ""='cd '
alias " "='cd '

Any ideas?

Answer 1

It's an option added in version 4.0 of Bash. You can set it with:

$ shopt -s autocd

Put that in your .bashrc file to enable it always.

Answer 2

I don't think you'll be able to have a "blank" alias, it doesn't really make sense..

bash version 4.0 added the autocd option, which is set by running shopt -s autocd (as mipadi answered)

There is no such option in previous versions of bash, annoying.
