Hi,
Please keep me CC'd.
bash package 4.4.012-2 on Arch Linux,
`version 4.4.12(1)-release (x86_64-unknown-linux-gnu)'.
I'm trying to enable history expansion in a non-interactive bash with
`set -H'.
$ printf '%s\n' ': foo' 'echo !!' 'set -H' ': bar' 'echo !!' |
> bash
!!
!!
$
I'd expect the second `!!' to be `: bar'.
What am I misunderstanding?
