piping and redirection

June 29, 2016

xargs – takes results from one command and uses them as arguments to another command.

&lt;command1&gt; | xargs &lt;command2&gt;

tee – takes stdin and prints to file and prints to screen. Thus to be able to capture and see output

&lt;command1&gt; | tee &lt;filename&gt;

Redirection

&lt;command&gt; &gt; file.txt 2&gt;&1

This sends stdin and stdout’s output to file.txt
