Machine Type: x86_64-pc-linux-gnu
Bash Version: 4.4
Patch Level: 20
Release Status: release
Description:
Setting/unsetting posix mode interferes with keybindings.
This is a problem e.g. with completion functions that use
process substitution; they need to control the posixness state
in order to not run into syntax errors when they happen to be
invoked in posix mode shells.
This is not limited to the above bash version, it has been
reported to happen with much newer ones as well. More info and
background at https://github.com/scop/bash-completion/issues/190
Repeat-By:
Add these lines to ~/.inputrc:
set editing-mode vi
Tab: menu-complete
Then, in a new shell:
$ bind -q menu-complete
menu-complete can be invoked via "\C-i", "\C-n".
$ shopt -uo posix # or -so, or set [+-]o
$ bind -q menu-complete
menu-complete can be invoked via "\C-n".
Notice how \C-i was lost. It does not matter whether setting
posix actually changed its state, happens also e.g. when
unsetting when already unset.
