The power of find and xargs

xargs cannot replace {} with a lot of arguments, so if mv did not have --target-directory, then xargs would have to do:<p><pre><code> find ... | xargs -0 -i {} mv {} ~/Pictures </code></pre> which would run one mv per file.<p>GNU Parallel <a href="http://www.gnu.org/software/parallel/" rel="nofollow">http://www.gnu.org/software/parallel/</a> allows for replacing {} with multiple arguments. So this would do the right thing:<p><pre><code> find ... | parallel -X -0 mv {} ~/Pictures </code></pre> GNU Parallel is useful for many other applications.

The examples are somewhat forced:<p><pre><code> find ~/Desktop -name "*.jpg" -o -name "*.gif" -o -name "*.png" \ -print0 | xargs -0 mv --target-directory ~/Pictures </code></pre> What's wrong with this?...<p><pre><code> mv ~/Desktop/**/*.{jpg,gif,png} ~/Pictures</code></pre>
