space elimination 1

[nappaji]

How do I eliminate spaces using PERL??.

say , I have
$_ = "bill gates "
or $_ "bill michael gates".

I want all the spaces eliminated and the o/p as
"billgates" or "billmichaelgates"

Thanks in advance.

These should work

$_ =~ s/\ //;

or for all whitespace

$_ =~ s/[\ \t\n]+//;

There are a number of things wrong with the above examples:

1. If you are using $_ you don't need to specify it.

2. You don't need to escape the space in the pattern.

3. You should be using the '+' flag for "one or more" after the space, it's more efficient.

4. You should be using the 'g' flag for "global", otherwise it will only remove the FIRST space.

5. What's wrong with using the whitespace pattern '\s'?

To remove just spaces (from $_) use:

s/ +//g;

To remove all whitespace (from $_) use:

s/\s+//g;
