Question
how to flush the input buffer ?
This is the code to get a y/n but when I make a subsequent call it does not ask for the input !
#! /in/local/bin/perl
sub demande {
my $in=0;
system("echo \"Have u modified \"");
$in = lc(getc);
$in =~ s/ //ge;
$in =~ s/\n//ge;
if ($in ne "y")
{
system("echo \"U are out NO BOSS .... $in\"");
exit;
}
else
{
system("echo \"U are in YES BOSS .... $in\"");
}
}
#end od demande

".. code to get a y/n but when I make a subsequent call it does not ask for the input !..."
What exactly are you trying to do? Can you explain in plain english what you are trying to acheive?
Let me know.
This will help you get a more accurate answer, faster.
Meanwhile, here is a sample script that will be run from the command prompt.
This script will ask the user for input.
If input is Y or y, then it will print a "YES" message.
If input is N or n, then it will print a "NO" message.
if input is anything else it will print a "INVALID" message.
#!/in/local/bin/perl
$|++; ## Disable output buffering
print "Enter your reply ";
$ans=<STDIN>; ## Read the users input
## Remove the newline character
chomp($ans);
if ($ans=~ /^y$/i){ ## Y or y entered!!
print "YES\n";
}elsif ($ans=~ /^n$/i){ ## N or n entered!!
print "NO\n";
}else{
print "INVALID\n";
}
