This Is Your Brain On Informatics

Testing out the fluids.

Below are the links to several pages with useful information from the class.

Linux

^k = delete line

^w = find

^u = undoes one typo

/etc/init.d = initiate daemon (it does something but it stays in memory?!)

find / -name foo This will search the whole system for any files named foo and display their pathnames. Here we are using the criterion -name with the argument foo to tell find to perform a name search for the filename foo.

If you get locked out of your server, enter pico /etc/hosts.deny Once you are in that file, delete the IP address (your IP address) that has been blocked at the bottom of the file.
