UNIX Command Dictionaries

The UNIX manual is mostly on line and the UNIX `man’ command is used to display parts of the manual. Typing
man [command] (CR)
will yield information in an almost readable format during a IBM Telnet session. The problem is that you have both UNIX and CMS paging the output. You respond to the UNIX paging prompt `:’ with a `(CR)’ return for a new page, `d (CR)’ for a short new page, u (CR)’ for a short page up (back), or `q (CR)’ to quit. For the CMS paging prompt `holding’, respond with the designated `Clear-key’. If you are using IBM Telnet, then `man [command]‘ usually produces poor output for the head of the display. The version `man -blou [command] (CR)’ should remove underscoring and other backspacing for printing at UIC, but does not work completely. For a quick overview of a command try the `-q’ quick option:
man -q command] (CR)
Alternatively,
man [command] > [file] (CR)
is useful for redirecting the output to a file that can later be transfer back to CMS for printing (e.g. by `printdoc’). The UNIX no paging `-r’ option does not work in a CMS session, so the CMS user has to press both the `Return-key’ for a new UNIX `man’ page or the `Clear-key’ for a new CMS page depending on the odd UNIX prompt or the CMS “HOLDING” prompt, respectively.
This abridged UNIX dictionary is only intended to be a short enough list to get you started without being bewildered by the enormous UNIX manuals, but with enough commands to be able to do something useful. For more information use the `man’ command or refer to some of the UNIX texts. UNIX is a trademark of Bell Laboratories.
The format is
[command] [generic operand] : [Definition.]
along with a carriage return `(CR)’ for each command. DO NOT FORGET that almost all UNIX commands must be in lower case. Do not attempt to learn all of this at once, but read some of it and try it out at an actual computer session.
