Hello,
I'd like to report an obscure bug I came across in pfsense which runs on
top of FreeBSD.
If I run a bash script in which I have
read -r -n1 -p "prompt: "
and instead of providing input, i ctrl-c the script,
the ash shell doesn't recover the terminal properly; backspace echos ^?
and the only way to delete characters is to hold shift and press
backspace. Also, if I use the -s switch for the read command in the
bash script, the problem gets even worse with the cursor not moving
anymore as I type and the text I type not being visible at all.
A solution was provided by pgas from #bash on irc.freenode.net, where I
solve this by trapping the ctrl-c signal and do 'stty cooked' before
exiting, which seems to give expected behaviour.
Best regards,
Jan
