The main source of online documentation is the man command.
This is an online Unix Reference Manual. The full syntax of any command
may be seen by typing
man command
The reference manual entry for the specified command will be displayed on the screen, with the display pausing after each screenful. At this point the following actions can be taken:
<Spacebar> display the next page
<Return> display the next line
/string display the next page containing string
h give a full list of man sub-commands
q quit from man and return to the command prompt
The command
man -k topic
will give a list of other man pages that contain information about the
specified topic. See man man for full details of the
man command.
Where possible, each section ends with the relevant manual page reference,
with the assumption that the csh (C shell) or tcsh (TC
shell) is being used. The default on the OUCS Unix systems, is the tcsh.
There is a general Unix help menu system; type help to access
this. There is a large help section (ie manual pages) for each shell; use
man csh, for example, to see the help for the C shell.
Other useful help commands are:
man -k topic
whatis topic
apropos topic
which topic
whereis topic
man topic/Indexname
man csh/Job would go straight to the Job Control section of
the manual pages for csh. Note, indexing is not available to all
shells.
manq topic
It is also useful to explore the manual pages for associated topics/commands; these are listed at the end of the manual pages for each topic.
Note, the conventional notation for references to Unix manual pages is
in the format of topic(section number). User commands are in section
1 of the manual pages hence a reference to passwd(1), for example, means
help can be found on the user command passwd by typing man
passwd. This notation is used throughout this document.
Users at Oxford University can also e-mail advisory@oucs.ox.ac.uk for direct help.
