Example usage doesn't work on GNU/Linux[edit]

Possibly just worth a mention that the example usage given:

sort file | uniq -c | sort -n

doesn't work on Linux. uniq pads the count value on each line with some whitespace, and sort expects the first character on the line to be numeric, otherwise it doesn't perform a numeric sort. The command line given will not work as described because the first character on each line piped into sort is non-numeric. (talk) 12:57, 21 December 2008 (UTC)

Works for me. I do this all the time on Linux. Edward (talk) 23:27, 31 January 2011 (UTC)

Article gives advice on how to do something[edit]

The first section of the article says "Be careful, uniq expects its input to be already sorted; sometimes sort -u is what you need." It should probably be reworded to sound more encyclopaedic or removed altogether.

Also, I was under the impression that sort -u was equivalent to sort | uniq. (talk) 04:40, 11 May 2009 (UTC)
