I got this subroutine from a friend (who originally got it from the
cookbook, I think).
#this subroutine trims leading and trailing white space from a variable
#it accepts either a variable or an array as its only argument
sub Trim{
my @out = @_;
for (@out){
s/^\s*(.*?)\s*$/$1/;
} #end for
return wantarray ? @out : $out[0];
} #end sub
$name = " John Doe ";
$name = Trim($name);
print ("$name\n");
would return:
John Doe
So, in your case, the script would return:
John
Tommy
Beth
This routine strips the leading and trailing spaces, so it would allow you
to maintain the space between the first and last name that you were worried
about.
Hope this helps...
