I've found it on the net some time ago and it simply emulates uniq, applied on the 2nd column.
Create a testfile with following content and play with it, try $0, $1, and $2 and see the difference:
genehunter,
how can you know that it didn't work? Just because our results differ?
I guess without having the original file it will be hard to find the error.
You will have to copy out e.g. the first 500 lines off the datafile in a tempfile and see if the results differ.
Maybe you can then attach that tempfile to your posting, so we all can examine it and try to find the error (if there is any )

NAMESPACE(6) Games Manual NAMESPACE(6)NAME
namespace - name space description file
DESCRIPTION
Namespace files describe how to construct a name space from scratch, an operation normally performed by the newns subroutine (see auth(2))
which is typically called by init(8). Each line specifies one name space operation. Spaces and tabs separate arguments to operations; no
quotes or escapes are recognized. Blank lines and lines with # as the first non-space character are ignored. Environment variables of the
form $name are expanded within arguments, where name is a UTF string terminated by white space, a /, or a $.
The known operations and their arguments are:
mount [-abc] servename old [spec]
Mount servename on old.
bind [-abc] new old
Bind new on old.
import [-abc] host "[remotepath]mountpoint
Import remotepath from machine server and attach it to mountpoint.
cd dir Change the working directory to dir.
The options for bind, mount, and import are interpreted as in bind(1) and import(4).
