FreeBSD Cheat Sheet

A collection of commands I use frequently and still don't remember.

pkg

Display the message after first installing the application

pkg show -D <pkg_name>

iocage

Setup a new jail with vnet

iocage create -n <jailname> ip4_addr="10.192.0.28/24" defaultrouter="10.192.0.1" allow_raw_sockets=1 vnet=on boot=on interfaces="vnet0:em0bridge" -r 13.2-RELEASE

zfs

Show holds on a specific snapshot

If snapshots return as dataset is busy upon deletion, they are either dependent or use a tag that prevents them from being deleted. The command below will display any holds on a snapshot.

zfs holds -r <snapshot_name>

Migrate dataset to new pool

zfs snapshot -r old_pool/<dataset_name>@relocate
zfs send -Rv old_pool/<dataset_name>@relocate | zfs receive -d new_pool/<new_dataset_name>

tcsh

Execute command from history

history | grep <command>
!<id command>
