I think that Debian is big enough for two small tools that have overlapping functionality (the're nothing wrong with more choice) so I asked my sponsor to upload the new release (which has even more features as described below). > > Some differences (from browsing the manual page and toying with it): > > > > * rl can pick lines from the input (you can say give me 10 random > > lines from this file), this can be done with and without recurring > > lines (my math/statistics knowledge is mostly Dutch but it's like > > drawing cards with and without replacing them to the deck). > > head/tail, sort, uniq can do them. The operation is subtly different in that lines from the input may be picked multiple times. uniq can only pick out lines that have the same content but does not distinguish between different lines. Also when using the --count option operation is much more efficient (memory usage) than randomizing the whole file and picking the first couple of lines. > > * I don't understart bogosort's default mode of operation > > (it just permutates until the file is sorted? at least it takes more > > time than I am willing to wait for it), with --nosort it behaves > > just like rl by default > > It works like "sort" with a less optimal algorithm. This is something that randomize-lines does not do.
