simple script to find the number of "tab"s...but,...

------------------------------
$x=" hi";
$tabspace=0;
while ($x =~ /\t/g )
{
$tabspace++;
}
print $tabspace;
---------------------------------

1.)when i tried it without "g" ($x = ~/\t/ )... when i run the script it utilizes around 95% cpu and system hangs and i did "End process" for perl.exe
2). and in the input string instead of using "tab key" i used "space" key "five times"... like "-----hi" ...........think that"-" is a space key.
i thought that five spaces (or four or six...)are equal to one tab...but i got printed 0 tabs....

windows environment...activestate perl...5.6.1

thanks in advance...

NAME
lr_environment - Export Lire configuration in shell script form SYNOPSIS
eval `lr_environment` DESCRIPTION
The lr_environment command is used to import the Lire configuration in Lire shell scripts. All of Lire configuration variables will be written in a format that can be evaled by the shell. Shell scripts don't usually have to use that command, since it is done by the defaults file sourced by each command. The old names used by when the configuration was done in shell script are also exported by this script for backward compatibility. AUTHOR
