"Press any key to continue" function ... Problem when <Enter> is pressed ...

"Press any key to continue" function ... Problem when <Enter> is pressed ...

"Press any key to continue" function ... Problem when <Enter> is pressed ...

(OP)
Hi everyone,

I included the following function into my latest script:

CODE

function fkt_continue
{
echo "\033[1;36mPress any key to continue (or <Q> to quit) ...\033[m"
stty -echo
stty raw
key=$(dd bs=1 count=1 2> /dev/null) > /dev/null
stty echo
stty -raw
if [ $key = "Q" -o "q" ];
 then
  exit 1
fi
}

So far so good and everything works fine except when you press the <Enter> key it will act like Q has been pressed and quit the script ... sad

Any ideas why that's so and what I can do about it ?

Best Regards,
Thomas

Hi

Irrelevant what you press, that will always evaluate to true :

CODE --> command line

master # key='Q'; [ $key = "Q" -o "q" ]; echo $?
0

master # key='q'; [ $key = "Q" -o "q" ]; echo $?
0

master # key='TSch'; [ $key = "Q" -o "q" ]; echo $?
0
There you wrote value of variable $key equals string "Q" or string "q" is not empty. I can not imagine the 2nd part of expression to ever be anything else but true.

Maybe you want this instead :

CODE --> shell ( fragment )

[ $key = "Q" -o $key = "q" ]

My goodness, must have been too much code for me lately so I missed the fact that I forgot the second $key ... winky smile

Thanks a lot ! smile
