Disabling command line buffering

[senget76]

Usually, every command we enter does not return anything until we press enter,
However, I would like to have user to enter one character only as their selection by using getc in perlscript

somebody suggest me to use "stty cbreak". Unfortunately, this command is not avialable. I hope somebody can help me out.

Thank you

This is well documented in the man page for termio (man 7 termio) under the section;

Non-Canonical Mode Input Processing (MIN/TIME Interaction)

Have it read. It explains how to setup so that a single key press can be processed in a script.

Hi,

The Term::ReadKey module should give you this in Perl.

#!/opt/perl5/bin/perl

use Term::ReadKey;

ReadMode 'cbreak';
$key=ReadKey(0);
ReadMode 'normal';

Rgds, Robin
