([[User:AndrewS|I've]] just checked on a more recent firmware version and there's now also '''<code>get_camera</code>''', '''<code>get_mem</code>''' and '''<code>hdmi_status_show</code>''' commands)

'''<code>vcgencmd measure_clock ''<clock>''</code>'''

Shows clock frequency, clock can be one of '''<tt>arm, core, h264, isp, v3d, uart, pwm, emmc, pixel, vec, hdmi, dpi</tt>'''.

root@raspberrypi:~# \

Shows core temperature of BCM2835 SoC.

root@raspberrypi:~# vcgencmd measure_temp
temp=42.8'C

'''<code>vcgencmd codec_enabled ''<codec>''</code>'''

Shows if the specified codec is enabled, codec can be one of '''<tt>H263, H264, MPG2, WVC1, MPG4, AGIF, MJPA, MJPB, MJPG, WMV9, MVC0</tt>'''. Please note this was run on a Pi with the [http://www.raspberrypi.com/ MPG2 and VC1 licences] enabled.

root@raspberrypi:~# \
> for codec in H264 MPG2 WVC1 MPG4 MJPG WMV9 ; do \
> echo -e "$codec:\t$(vcgencmd codec_enabled $codec)" ; \

H264: H264=enabled
MPG2: MPG2=enabled
WVC1: WVC1=enabled
MPG4: MPG4=enabled
MJPG: MJPG=enabled
WMV9: WMV9=enabled

If you also follow the instructions in this [http://www.raspberrypi.org/phpBB3/viewtopic.php?p=269992#p269992 Forum post] then the codec options for VP6 and VP8 (WEBM) also work, this is experimental and unsupported at present so any changes are at your own risk.

'''<code>vcgencmd get_config ''[config|int|str]''</code>'''
Will print the configurations you have set. Argument can ether be a specific option or int, showing all configs with number-datatype, or str showing all configurations with datatype sting (aka text).

root@raspberrypi:~# vcgencmd get_config int
arm_freq=1000
core_freq=500
sdram_freq=600
over_voltage=6
disable_overscan=1
force_pwm_open=1

'''<code>vcgencmd get_mem ''arm/gpu''</code>'''

Shows how much memory is split between the CPU (arm) and GPU.

root@raspberrypi:~# vcgencmd get_mem arm && vcgencmd get_mem gpu
arm=448M
gpu=64M

'''<code>vcgencmd version</code>'''

Shows the firmware version

root@raspberrypi:~# vcgencmd version
