I am pretty excited to say that I will be taking the RHCE in a month or so as part of a week long bootcamp.

Now I use RHEL every day and have done so for several years and I have certain processes for doing things, and commands that I use all the time. Below is a list of information/commands that I just never used or are not familar with that I have run across in my search for test prep information.

• touch /etc/forcefsck, forces a filesystem check at next reboot.
• chattr – change file attributes, like chattr +i write protects a file
• ntsysv -gui utility for managing startup services]
• grub-install /dev/sda – reinstalls grub, do a –recheck first however
• mdamd – use to manage software raid
• /proc/mdstat – shows status of md devices
• labelfs – used to label filesystems
• system-config-network – gui for changing network configs
• system-config-printer – gui for setting up printers
• at, atq, atrm – schedule a one time job, view & remove jobs
• yum groupinstall "x window system" - installs x
