Actually, the content of the file looks something like:-
name=john
id=12345
password=12345
colour=blue
I am trying to grab the value field of each line and assigned it to be a
variable.
I tried the regular expressions, but seems like the syntax is wrong or
something,
@file = <filehandle>; #small file anyway
$file[0] is equal to 'name=john' but i just wanna extract john to be my
scalar variable.
like print $name but returns john only and the same extraction method for
the rest of the other 3 fields as well.
kindly advice!... million thanks!
