Re: Better "uniq" idiom?

If you just want a one-liner to unique a list, I'd use sort -u filesToUniq instead. It will use much less memory than your one-liner, and it's faster to type.

True, but it has the downside of doing a sort first, which could kill you on a long file which has many repeated lines... If the file is mostly unique, your way wins hands down, no question. But I usually wind up "uniq"ing on a field, so I usually see only about 10-100 lines per file. It would be interesting to benchmark. -- Mike	[reply]
