It&#x27;s moreso for when you spend time crafting the <i>perfect</i> command, and dont&#x27; want to repeat yourlself. Example..<p>find . -type d -print0 | sort -z | xargs --null -I &#x27;{}&#x27; du -sh &#x27;{}&#x27; | sort -h<p>Simple and clear; but history gives you the convenience to do find&lt;C-R&gt;&lt;CR&gt; and having the command run with out parameter&#x2F;typo verification.
