Want to see how much virtual memory you're using? Just type "swapinfo" tobe shown information about the usage of your swap partitions.

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

If other operating systems have damaged your Master Boot Record, you canreinstall it with gpart(8). See"man gpart" for details.

Time to change your password? Type "passwd" and follow the prompts. -- Dru <genesis@istar.ca>

You can limit the depth of the displayed datasets in the "zfs list" outputusing the -d parameter. To display only the first level of datasets belowmypool/usr and not the ones deeper than those, run this command:zfs list -d 1 mypool/usr -- Benedict Reuschling <bcr@FreeBSD.org>

Simple tcsh prompt: set prompt = '%# '

You can delete a range of ZFS snapshots (a-z) in multiple ways.The following will delete d and all earlier snapshots: zfs destroy mypool/data@%dTo delete d and all later snapshots:zfs destroy mypool/data@d%To delete all dataset snapshots:zfs destroy mypool/data@%Make sure to let ZFS perform a dry run (-n option) first and display (-v) whatit would do to confirm that the delete operation is removing exactly what you intended. -- Benedict Reuschling <bcr@FreeBSD.org>

You can use the 'fetch' command to retrieve files over ftp, http or https. fetch https://www.FreeBSD.org/images/beastie.pngwill download the beastie image from the FreeBSD web site.

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

"man ports" gives many useful hints about installing FreeBSD ports.

Can't remember if you've installed a certain port or not? Try "pkg info-x port_name".

Want to find a specific port? Just type the following under /usr/portsor one of its subdirectories: make search name=<port-name> or make search key=<keyword>

Want to go the directory you were just in?Type "cd -"

Want colour in your directory listings? Use "ls -G". "ls -F" is also useful,and they can be combined as "ls -FG".

You can install extra packages for FreeBSD by using the ports system.If you have installed it, you can download, compile, and install software byjust typing # cd /usr/ports/<category>/<portname> # make install && make cleanas root. The ports infrastructure will download the software, change it soit works on FreeBSD, compile it, install it, register the installation so itwill be possible to automatically uninstall it, and clean out the temporaryworking space it used. You can remove an installed port you decide you do notwant after all by typing # cd /usr/ports/<category>/<portname> # make deinstallas root.

"man hier" will explain the way FreeBSD filesystems are normally laid out. -- David Scheidt <dscheidt@tumbolia.com>
