NAME

SYNOPSIS

DESCRIPTION

The following options are available:

-k

Print the version and patch level of the installed kernel. Unlike uname(1), if a new kernel has been installed but the system has not yet rebooted, freebsd-version will print the version and patch level of the new kernel.

-r

Print the version and patch level of the running kernel. Unlike uname(1), this is unaffected by environment variables.

-u

Print the version and patch level of the installed userland. These are hardcoded into freebsd-version during the build.

-j jail

Print the version and patch level of the installed userland in the given jail specified by jid or name. This option can be specified multiple times.

If several of the above options are specified, freebsd-version will print the installed kernel version first, then the running kernel version, next the userland version, and finally the userland version of the specified jails, on separate lines. If neither is specified, it will print the userland version only.

IMPLEMENTATION NOTES

To determine the name (and hence the location) of a custom kernel, the freebsd-version utility will attempt to parse /boot/defaults/loader.conf and /boot/loader.conf, looking for definitions of the kernel and bootfile variables, both with a default value of “kernel”. It may however fail to locate the correct kernel if either or both of these variables are defined in a non-standard location, such as in /boot/loader.rc.

ENVIRONMENT

ROOT

Path to the root of the filesystem in which to look for loader.conf and the kernel.

EXAMPLES

/bin/freebsd-version -u

To inspect a system being repaired using a live CD:

mount -rt ufs /dev/ada0p2 /mnt
env ROOT=/mnt /mnt/bin/freebsd-version -ku
