More unix stuff to know. Probably not the fancy stuff, that'll come in Lesson 3.

1. Try out

• pine

You'll be in the pine email program, easier to use than mutt cause its got instructions on the screen.

2. Try out

• cd public_html less index.html

Less is a text viewing program, and as all unix files are viewable text files, its useful for looking at stuff. You can use page up and page down keys, as well as arrow keys, space goes one page down and - goes one page up, and q quits less.

• q

Less is quit and you are back at the prompt.

3.

• less index.html

Try out control-z this is a special command to suspend processes which are things which are run/executed by a computer.

4.

• ps -aux|grep <yourloginnameherepleasewithoutthe<>'s>

You should see all the processes that you are running, find the one that relates to less index.html, its got a five digit number in the second column. That is the process id number.

• kill -9 <fivedigitnumberhere>

Which kills the suspended process.

5. control-z, control-x, and control-c are all special for unix, control-z is suspend, and control-c is kill, and control-x is exit perhaps.
