Wouldn't it be easier to change the message to "press Enter to continue" ? :-)
Since 'read' uses buffered input, you have to wait till Enter is hit.

Hi Guru,

the read-command allways reads from standard input. The input is stopped by the return-key. So it doesn't matter which keys are pressed, the input is ALLWAYS stopped by the return-key.

Allways stay on the bright side of life!

Hi,

If you have perl, this should do it:

======================================
#!/opt/perl5/bin/perl
system "stty -icanon";
$key=getc;
system "stty icanon";
print "\n";
======================================

Rgds, Robin.

But there is another question, i cant find it, that uses a command to do it.
