Bug with Ctrl+Z after Vim (bash)

[tuanpham96]

I've been running into this issue with Ctrl+Z lately in bash.

• Enter vim like vi ~/.bashrc
• Press Ctrl+Z to put in background mode
• Now type anything like ls
• Issues: no typing of the command is visible but the output of the command is

This happens if I have source ~/.fzf/plugin/fzf-bash-completion.sh ; bind -x '"\t": fzf_bash_completion' in my .bashrc.

btw you can type stty sane and you back to normal

thanks @TuM0xA-S!

following that, for troubleshooting if anyone is interested, here's the diff between the default (start of shell, stty-def.txt) after doing the Ctrl+Z thingy (stty-bug.txt) and after doing stty sane command (stty-aftersane.txt). I'm still reading through what these different settings are but the noticeable ones are [-]echo, lnext and discard that got changed.

i found workaround:
just place it PROMPT_COMMAND="stty $(stty -g)" in you bashrc.
it just resets terminal to its initial state before printing prompt
