blocks|key|26626|text|这里是第一次尝试，这在编码器上很容易，但在CPU上很难，它在每行前面加上一个随机数，对它们进行排序，然后从每行中剥离随机数。实际上，这些行是随机排序的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|26627|cat+myfile+%7C+awk+'BEGIN{srand();}{print+rand()"\t"$0}'+%7C+sort+-k1+-n+%7C+cut+-f2-+>+myfile.shuffled|code-block|syntax|javascript|26628|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

A one-liner for python:

And for printing just a single random line:

Simple awk-based function will do the job:

<pre><code>shuffle() { 
 awk 'BEGIN{srand();} {printf "%06d %s\n", rand()*1000000, $0;}' | sort -n | cut -c8-
}
</code></pre>

usage:

<pre><code>any_command | shuffle
</code></pre>

This should work on almost any UNIX. Tested on Linux, Solaris and HP-UX.

Update:

Note, that leading zeros (<code>%06d</code>) and <code>rand()</code> multiplication makes it to work properly also on systems where <code>sort</code> does not understand numbers. It can be sorted via lexicographical order (a.k.a. normal string compare).

Example:

<pre><code>the

To shuffle the lines, do:

<pre><code>$ shuf words.txt

which would throws the shuffled lines to standard output; So, you've to pipe it to an output file like:

One such shuffle run could yield:

<code>brew install randomize-lines</code>

After issuing this command, maclist_temp.txt will contain a randomized list of lines.

Hope this helps.

<li>The <a href="https://git.fruit.je/unsort" rel="nofollow noreferrer"><code>unsort</code></a> util. Syntax (somewhat playlist oriented):

<pre><code>unsort [-hvrpncmMsz0l] [--help] [--version] [--random] [--heuristic]
 [--identity] [--filenames[=profile]] [--separator sep] [--concatenate] 
 [--merge] [--merge-random] [--seed integer] [--zero-terminated] [--null] 
 [--linefeed] [file ...]
</code></pre></li>
<li><a href="http://www.billposer.org/Software/msort.html" rel="nofollow noreferrer"><code>msort</code></a> can shuffle by line, but it's usually overkill:

<pre><code>seq 10 | msort -jq -b -l -n 1 -c r

I want to shuffle the lines of a text file randomly and create a new file. The file may have several thousands of lines.

How can I do that with <code>cat</code>, <code>awk</code>, <code>cut</code>, etc?

How can I shuffle the lines of a text file on the Unix command line or in a shell script?

我想随机排列一个文本文件的行，然后创建一个新文件。该文件可能有几千行。我如何使用cat、awk、cut等实现这一点？
