Randomize lines in a file

Works in sort (GNU coreutils) 7.4, don't know when it was implemented but sometime the last 6 years.


There is 1 alternative - vote for the best!

Terminal - Alternatives
awk 'BEGIN{srand()}{print rand(),$0}' SOMEFILE | sort -n | cut -d ' ' -f2-

This appends a random number as a first filed of all lines in SOMEFILE then sorts by the first column and finally cuts of the random numbers.

Seeing that _sort_ its been used, why not just _use_ it. ;)
