Interesting commands for the Linux shell
nice collection! upvoted for "15. `namei -l`" alone, which is far too little known.<p>a better "20. Randomize lines in file":<p><pre><code>  shuf file.txt
</code></pre>
instead of<p><pre><code>  cat file.txt | sort -R
</code></pre>
(sort -R sorts by hash, which is not really randomisation.)
