In several places, I have simply inserted the code as a script to be downloaded. I tend to keep things like this around so I can just run a simple command instead of copying/pasting an entire line.

findDrives.sh

#! /bin/sh
 
egrep '(ad|cd|da)[0-9]' /var/run/dmesg.boot | sort

Or, simply run

geom disk list

usbconfig

Following command will show you the temperature of each core of a processor

sysctl -a | grep temperature | grep cpu

iotop is a well known utility under Linux, but not available for FreeBSD. However, the following command will do the same thing (does not apparently work for iSCSI devices)

top -m io -o total

Under Linux, watch repeats a command over and over, so it is useful for monitoring long running processes. The FreeBSD command cmdwatch does the same thing, with the same flags.

cmdwatch zpool iostat -v

I was used to Debian's apt-get, and used the -y (answer “Yes” to all questions) parameter. Looking for something similar for pkg, I ran across http://dan.langille.org/2013/12/06/bootstrapping-installing-pkg-on-freebsd-unattended-and-without-answering-yes/ which showed a possible answer; set an environmental variable as part of the call.

env ASSUME_ALWAYS_YES=YES pkg install p5-libwww

will install LWP (p5-libwww) without waiting for you to select “Yes”

After a while, your pkg cache will use more and more space on your disk, with copies of packages you have already installed. The following command cleans that cache.

pkg clean

By default, a new user is not able to become root. To do this, you must add them to the wheel group. Use the following command

pw user  mod  username -G wheel

where username is the username of the user who has access

I just like bash for my shell. While it is not the standard for BSD, it is much more powerful than the standard sh, so I like to use it for my personal account. Once bash is installed, set it as the default shell for a user.

chsh -s bash username

Warning: do not modify the root account's shell. You will break your system. If you want a bash script to run as root, be sure to include

#! /usr/bin/env bash

at the head of your scripts.

• zfs unshare -a
• zfs share -a
• showmount -e
