Question about bash read function and matching ESC
I am trying to match the ESC key in bash. The code below works as
intended when I try to match a 'normal' key like 's' or so. But it will
not for the escape key. This makes me expect this has something to do
with the high-bit stuff, but I haven't figured out how to work around
it. Anyone have a suggestion?
if read -n 1 -s -t 3 KEY ; then
if [ "$KEY" == '\x1B' ]; then
echo BAILOUT: nothing done
#Do something useful here...
echo TIMEOUT: nothing done
Thanks for your time.
