Actually, except the `SHARE_HISTORY` option (which can be emulated), everything else is available in Bash.

[pyre]

Sorry, I just copy-pasted the whole thing. I know that most of the other options are available, though I didn't know that the HIST_IGNORE_SPACE was available in bash.

In bash you'd use HISTCONTROL=ignorespace

[pyre]

According to the manpage, ignorespace doesn't treat multi-line commands very nicely.

You would have to disable the cmdhist option for that to matter:

  shopt -u cmdhist

Or I guess be working with a bash old enough to not support cmdhist.
