Keyboard Hit

Thereis a command or function in the HP-UX Release 10 like the function kbhit() in the C languages for use in scrips shells programming?

Hi,

there is no command for this at HP-UX.
Put you a C source at attachment that will do it.

There is some sample C code in the Unix programming FAQ at

http://www.landfield.com/faqs/unix-faq/programmer/faq/

Question 3.3 is the one to look at.

Would switching the terminal to raw mode in order to get the unbuffered keyboard input be of help?

Then maybe you could do something like:

echo 'hit key to continuec'
stty raw -echo
byte=`dd count=1 bs=1 2>/dev/null`
stty -raw echo
echo 'nnext statement'

But make sure to read the WARNINGS stanza in the stty manpage.

I apologize if this reply appears twice, but somehow the forum's webserver didn't swallow my first posting.

Sorry,

forgot to escape the backslash for \c at the end of the 1st echo statement as to make it visible in this forum.
