Prints all the files with the name file and then a 1 character directly after. Will print 10, 11, 12 because the astrix means stuff can come after as long as it begins with a number between. If you want to write more than one command on the same line, break it up with a semicolon semicolon. Immediate subdirectories it has plus its parent directory and itself. Sudo cat atextfile. txt : prints out the contents of a file. Change the permissions of a file using the chmod command. Example: rwx rwx rwx = chmod 777 filename.
