ps output varies by OS and depends on the flags you give it. Also I have
found some fields are empty and fields are fixed sized, sometimes without
whitespace between the fields. Given the fields are fixed length, you can do
something like this with a regex and pick out the fixed size fields:
/(.{5})({.{8})/;
$field1 = $1; # 5 characters wide
$field2 = $2; # 8 characcters wide
See the perlre man page for details on the {n} notation.
You may have to delete leading and trailing whitespace with this method. And
the field size is heavily dependent on what version of ps you use. Some
versions of ps support user defined format. So you might take a look at using
that, if the code is not intended to be portable across OS versions.
