The document provides information on useful UNIX commands for viewing files and directories (ls, cd), viewing files on screen (more), editing files using editors like pico and vi, printing files using lpr, downloading files from UNIX to a PC or Mac using ftp, and invoking a UNIX shell like the C shell environment.

1. Useful UNIX commands are:
ls to see the names of files and directories you have
cd to change directories (e.g. cd mydir changes to directory mydir)
more to print file on screen (e.g. more myfile to see myfile)
2. EDIT FILES
There are many possible UNIX editors to use.
The easiest to use is pico. Give the UNIX command
Pico
Then use the on-line help (^G where ^ is obtained by shift 6).
Other UNIX editors include vi and ex.
Alternatively, you can download a file to the PC or MAC and use a PC or
MAC editor. Downloading is discussed below.
3. PRINT FILES
Print files using UNIX command
lpr -h
You need to additionally give the name of the printer and the file.
Printer names will change over time. The UNIX command news gives a lot
of information, including the current printers. This is given below.
For example, to print file myfile in Hutchison 76 [will not work any more]
lpr -h -P76hutcha myfile
The -h option saves a page by not giving a header page.
If you get a large file by ftp, gopher, mail, etc. and only need part of it,
then first edit it using pico (eliminate unwanted lines by the ^k command)
or some other editor to extract what you want.
4. DOWNLOAD FILES FROM UNIX TO PC OR MAC
Use an ftp program such as WSFTP
5. INVOKE A UNIX SHELL
Different UNIX environments exist with different ways to invoke UNIX commands.
The UNIX C Shell environment is preferred.
New accounts are sent to this. Old accounts you may want to change to the
C shell environment as discussed below.
To get information on the C shell commands give the UNIX command man csh
This gives very lengthy output.
