Having trouble using fetch through a firewall? Try setting the environment
variable FTP_PASSIVE_MODE to yes, and see fetch(3) for more details.

By pressing “Scroll Lock” you can use the arrow keys to scroll backward
through the console output. Press “Scroll Lock” again to turn it off.
%
Want colour in your directory listings? Use “ls -G”. “ls -F” is also useful,
and they can be combined as “ls -FG”.

If you need to ask a question on the FreeBSD-questions mailing list then

http://www.freebsd.org/doc/en_US.ISO8859-1/articles/
freebsd-questions/index.html

contains lots of useful advice to help you get the best results.

If you’d like to keep track of applications in the FreeBSD ports tree, take a
look at FreshPorts;

%
To search for files that match a particular name, use find(1); for example

find / -name “*GENERIC*” -ls

will search ‘/’, and all subdirectories, for files with ‘GENERIC’ in the name.

In tcsh, you can `set autolist’ to have the shell automatically show
all the possible matches when doing filename/directory expansion.
%
You can `set autologout = 30′ to have tcsh log you off automatically
if you leave the shell idle for more than 30 minutes.
%
If you `set filec’ (file completion) in tcsh and write a part of the
filename, pressing TAB will show you the available choices when there
is more than one, or complete the filename if there’s only one match.
%
You can press up-arrow or down-arrow to walk through a list of
previous commands in tcsh.
%
You can disable tcsh’s terminal beep if you `set nobeep’.
%
If you `set watch = (0 any any)’ in tcsh, you will be notified when
someone logs in or out of your system.
