Re: a way to do 'sort|uniq'

cat file.txt|sort|uniq
[download]

Deleting the useless use of cat, and using a far-underused sort flag, I'd type that as:

sort -u file.txt

That search doesn't result in anything particularly useful. The first match, the one which looks the most promising and the one which refers to you by name, is a broken link. A cached version is readable. It would be nice if you provided a link to your document instead of having us wade through broken links trying to figure out what you mean.	[reply]

...the useless use of cat... What do we have here?! It sure looks like a useless use of "use of"¹. What's wrong with "the useless `cat`"? :-) ¹Or, if I'm to practice what I preach, a useless "use of". the lowliest monk	[reply]

That's actually part of the joke, that the "award" itself is broken in a way similar to the item about which it complains. -- Randal L. Schwartz, Perl hacker Be sure to read my standard disclaimer if this is a reply.	[reply]

I was generalizing the construct - I usually do something like: `$ tail +2 file.txt\|tr -dc '[0-9\n]'\|sort\|uniq -c\|sort -rnk 1` [download] I realize that the 'cat' would be useless in the simplified example that I gave, but the point was I wanted a way to do that same type of thing all in one step with perl.
