A storehouse of useful information

"The more I know, the more I realize that I know nothing."

Even if you are not a teapot for a long time and are not afraid to increase the relative level of your ignorance - try to do it on your car:
sudo apt-get install fortunes-ubuntu-server
and then just call
/usr/bin/ubuntu-server-tip

Multiple mental orgasm guaranteed.
Here are just some examples:

• To create a copy of the file without duplicating the file path, use the '$
  cp /long/path/to/file/nameiet,.orig} ', which will create a copy of the file with the suffix ".orig".
• If you execute the command and forget about 'sudo', you can type 'sudo !!'
  to run the previous command a second time using 'sudo'.
• Subsequent commands usually take a similar argument. 'Alt-.' inserts
  last argument of the previous command. Reading documentation taxis!
