Working with Mac OS and Linux Chapter Eighteen Working with Mac OS and Linux

220-902 Objective Covered 2.1 Identify common features and functionality of the Mac OS and Linux operating systems.

Best Practices Scheduled backups Scheduled disk maintenance System updates/App store Patch management Driver/firmware updates Antivirus/Antimalware updates

Tools Backup/Time Machine Restore/Snapshot Image Recovery Disk Maintenance Utilities du, df, and fsck Shell/Terminal Bash OpenSSH Screen Sharing Force Quit

Mac OS X Features Multiple Desktops/Mission Controls (switch between apps/desktops) Key Chain (password management system) Spot Light (search for documents, images, apps …) iCloud (small amount free, but anything beyond that requires payment) Gestures Finder (browse through folders and find files, disks, apps …) Remote Disk (access files on a disc in another machine) Dock (set of icons) Boot Camp (choose OS as you boot)

Linux Utilities: Managing Files and Directories Command Name Action cd Change the current directory. chmod Change file permissions. chown Change the file owner and group. cp Copy files. ls Display the contents of a directory. mkdir Create a directory. mv Rename a file and move the file from one directory to another. rm Delete files. pwd Display the current directory.

Linux Utilities: Processing and Managing Files Command Name Action dd Copy blocks of data from one file to another (used to copy data from devices). grep Search for regular expressions in a text file. apt-get Download files from a repository site. ps Display a list of currently running processes. shutdown Shut down Linux. vi Start the visual file editor.

Linux Utilities: Managing Users Command Name Action passwd Change the password. su Start a new shell as another user (the other user is assumed to be root when the command is invoked without any argument). sudo Allows you to run a command as another user (usually the root user)

Linux Utilities: Networking Command Name Action ifconfig View and change information related to networking configuration. iwconfig Similar to ifconfig, but used for wireless configuration

Permissions Who Action Permission u (user) + (add) r (read) g (group) - (remove) w (write) o (others) = (assign) x (execute) a (all) s (set user ID)
