No, you wouldn't. You would like to remove possible whitespace from
the beginning and end of a string.
my($word) = " Detail Design Activity Included ";
$word =~ s/^\s*(\D*)\s*$/$1/;
It's best done using two substitutions:
$word =~ s/^\s+//;
$word =~ s/\s+$//;
Thanks a ton Gunnar,
How about the intermediate blanks? Is there a way to recursively take
all blanks/tabs that occur??
Did you really want that? In that case I misunderstood you; Please
disregard my previous suggestion.
To actually remove *all* whitespace, you can simply do:
$word =~ s/\s+//g;
Read about the /g modifier in the description of the s/// operator in
"perldoc perlop".
