steps to produce
hide cursor
setterm -cursor off
call the bash built-in read command as follows: silent, wait 1 second, read
1 character to variable KEY
read -s -t 1 -n 1 KEY
while the read command is in a loop, control + c is trapped successfully
and the cursor is un-hidden
setterm -cursor on
expected results:
cursor is visible and typed keys are echoed to screen as before
actual results:
cursor is visible, keys are no-longer echoed to the screen until
terminal is closed
additional notes
command: setterm -default cannot fix
os: fedora 21
bash version: bash-4.3.30-2.fc21.x86_64
tested in various terminal emulators, and the console (alt+Fn, where
n=1-8)
