– File Permissions, RBAC, Compensating controls, SUDO, Service Level Accounts Basic UNIX requirements • how and when to use ^c, ^d, and ^z.

• how to use pipes and redirects. If ?, ??, 2?, and 2&1 aren't second nature to you, you need to make them so.
• how to use /dev/null both to make output disappear and to empty files.
• how to use of $? (the return code or "exit code") to determine if the previous command (usually within a script) completed successfully.
• how to use regular expressions with commands such as ls, grep and perl.
• the effect of various quotes – how single and double quotes differ and how ` (backticks) can be used to add command output to a line.
• how to add and remove accounts (with or without removing the associated directories).
• how to work with permissions, timestamps, owners, and groups -- and how to determine if additional permissions have been assigned with the setfacl command. You should also get to know how to work with the security context of files when SELinux is in use.
• how to use essential Unix utilities like grep, awk, sed, and wc.
• how to use text editors. In fact, you really should know vi, though if it takes some time to get used to.
• Even if you love desktop editors like Gedit, you will someday find yourself on a command line with no other option. Besides, vi (along with its colorful variation, vim) can make a lot of the work that you do go a lot faster once you know how to use it well. • scripting basics. You need to be very good at basic scripting – using if, for, and while commands if not also case statements and functions.
• how to work with processes – understanding ps output, knowing the kind of information you can get from /proc and how to use tools like lsof for determining what files a process has open.
• how to set up a new file system, look at disk space, track down large files, use fsck, and find files using many different criteria (size, ownership, permissions, type, etc.).
• where to find key directories and configuration files – those in /etc (e.g., /etc/hosts, the passwd and shadow files) and those in other locations (e.g., /etc/mail/sendmail.cf, /etc/samba/smb.conf).
• how to set up essential services (e.g., naming, printing).
• how to install packages using yum and apt-get and also how to install software from tar.gz files. • how to apply patches, Solaris + RHEL
• how to monitor systems using commands such as df and du to look at disk space, and commands like top and sar to monitor and evaluate performance.
• how your systems boot – their dependence on "start scripts" and whether they use systemd or upstart init services.
• how to use basic commands like dump and tar to back up directories or entire file systems.
• how to interact with other systems – logging in using ssh, moving files with scp and sftp, and using rsync for synchronizing individual files or entire file systems.
• how to view and manipulate timestamps on files, including using the touch command.
• how to configure a network interface; how to use the ifconfig and ip addr commands; how to set up the /etc/sysconfig/network file; when to use /etc/hosts and the hostna
