Summary

Video starts off correcting an error from the first video, presenter forgot to cover the copy (cp) command, this is discussed at the start of the video.

Example 1 – make a backup of a file

cp file1.txt file2.bak.txt

Example 2 – Copy a file to home directory

Lets say we are in /home/user/junk (like in the video):-

cp file1.txt ~/ will copy to home directory. You can use cd,, to drop down a level in the file system to /home/user to confirm this.

Also use wildcards e.g

cp *.txt will copy any files with .txt as the extension.

User permissions

chmod – change mod using sudo on its own has a time out sudo -s assumes the root user to root until you type exit

root user has a # normal users have $

changing owner permissions

chown – change owner

chown user:group file.txt

You need to be root for this so use sudo chown user:group file.txt
