  This just might be the single greatest video I've ever watched in YouTube.

  CTRL U does remove the text on the line, if you are at the end of the line. What it is actually doing is removing from your cursor to the BEGINNING of the line. If you are in the middle of the line, it will remove everything BEFORE the cursor. Also, if you are in the middle of the line and type CTRL K, it will remove everything from the cursor to the END of the line. If you do CTRL A CTRL K, it is the same as CTRL U as you are going to the beginning and removing text to the end of the line.<br>truncate was a new command for me (I&apos;ve used &apos;cat /dev/null &gt; filetoempty&apos;)<br>and I learned about column, too!<br>Cool video!

  summary of the commands:<br><br>1. `cd -` : back to the last directory we&apos;ve been to. <br>2. `ctrl+l`: clear screen <br>3. `reset`: clear on steroids - resets terminal session <br>4. `pushd /var` + few other `cd` commands + `popd`: commands that allow you to work with directory stack and change the current working directory <br>5. `vim /etc/ssh/sshd_config` + ctrl+fz : isn&apos;t closing, but minimizing the window to the back ground <br>`fg` : bring back the window to the front. <br>6. `apt update`: would fail - cuz we fogot sudo <br> `sudo !!` : would run the last command as sudo <br>7. <br>8. run command that already been run - `history`, choose a number of command <br>and run it `!102` -&gt; the 102 command from the history would run again <br> <br>9.HISTTIMEFORMAT=&quot;%Y-%m-%d %T&quot; <br>`history` would should the history commands by the format. <br>another way to add the format, is add it to the `~/.bashrc` file with `vim` or `nano` commands. <br> <br>10.cmatrix -&gt; let you look cool + ctrl c to escape <br> <br>11.adjust font `shift +` or `shift -`, `reset` command would reset the font size <br> <br>12. `ctrl a` - start of the line <br>`ctrl e` - end of the line <br> <br>13.chainning commands -&gt; `ls -l; echo &quot;hello&quot; ` <br>or -&gt; `ls -l &amp;&amp; echo &quot;hello&quot; ` <br>&amp;&amp; - would stop when meets an error <br>; - would pop up an error and keep on running the second/next command <br> <br>14. `tail` / `head` commands to see top or bottom of a file. <br> <br>15. truncate (be cautious while using this one - its risky) <br>it allows to change the size of a very large files (like log files) <br>for example `truncate -s &lt;size_of_file&gt; &lt;name_of_file&gt;` == truncate -s 0 hello.txt to empty the hello.txt file<br> <br> <br>16. `mount | column -t` : make sure all the output shows in columns <br>any verbose and messy command output would look better using `| column -t`

  25+ years of command line advanced usage but with your video I learned about column -t and the history time variable

  Man you are one of the best Linux tutorial guys on here. &nbsp;Always easy to learn from your videos

  I hate to say this but many of the tutorials out there, the folks talking are hard to understand. I know that sounds bad, but it&apos;s a real issue either way. &nbsp;I greatly appreciate that you are in depth and easy to listen/hear. Thank you very much.

  Very good video on the command line. &nbsp;I&apos;m 75 and grew up with UNIX while working with Bell Labs and developing software using C. &nbsp;I&apos;ve been to a number of Unix Administration schools while working at Western Electric including Unix Internals. &nbsp;Back then there was no GUI and it was all command line interface on the terminal. &nbsp;I still have vi highly ingrained in me and today only use Ubuntu Linux. &nbsp;I really enjoyed your video and picked up a lot of new tips and some that shucked the old cobwebs into remembering. &nbsp;Thanks for the very well done video.

  Great video! I have been using Linux for 3 years and come from a Windows admin background but this old dog still managed to learn some new tricks.

  Thanks for another great video. <br>One small side note, the &quot;ctrl+u&quot; will ((at least on my &quot;Pop-OS 21-04&quot;)) indeed work as You demonstrated.<br>How ever what it &quot;really does&quot; is &quot;deletes&quot; all the entered text to the left of the cursor. <br>So if the cursor is &quot;at the end&quot; of the line it will indeed &quot;delete the full line&quot;, but if the cursor instead is at the start it will do nothing. And of course if You have the cursor &quot;somewhere in the middle&quot; it will just &quot;delete&quot; the text to the left of the cursor<br>Just thought I&apos;d mention that (possibly petty) detail :)<br>Best regards.
