Raspberry Pi Turn Tv On/Off CEC – Tim Leland

Posted by jpluimers on 2021/10/13

[WayBack] Raspberry Pi Turn Tv On/Off CEC – Tim Leland (with some quote fixes) via [Archive.is] Brad Fitzpatrick on Twitter: “lol tear (from )… “:

Install cec-utils

Once everything is installed you should be able to control the tv using the command below:

  • Turn tv on: echo 'on 0' | cec-client -s -d 1
  • Turn tv off: echo 'standby 0' | cec-client -s -d 1
  • Set active source: echo 'as' | cec-client -s -d 1
  • Tv status: echo 'pow 0' | cec-client -s -d 1

Troubleshooting Tips:

  • Make sure your tv supports cec and that it is enabled. Tv manufactures call CEC by different names so you may have to do some research depending on your brand.
  • Make sure you are using a new hdmi cable that is at least HDMI 1.2a

Different names for HDMI CEC

  • Samsung – Anynet+
  • Sony – BRAVIA Link or BRAVIA Sync
  • Sharp – Aquos Link
  • Hitachi – HDMI-CEC
  • AOC – E-link
  • Pioneer – Kuro Link
  • Toshiba – Regza Link or CE-Link
  • Onkyo – RIHD (Remote Interactive over HDMI)
  • LG – SimpLink
  • Panasonic – VIERA Link or HDAVI Control or EZ-Sync
  • Philips – EasyLink
  • Mitsubishi – NetCommand for HDMI
  • Runco International – RuncoLink

Some links on xargs simulation in PowerShell

Posted by jpluimers on 2021/10/13

On nx, I’m used to xargs which allows to convert from a pipe of output into arguments passed to a command. This is useful, as many commands only accept arguments as parameters.

In PowerShell, you can usually avoid an xargs equivalent because commandlet output is a stream of objects that you can post-process using . I for instance used that in PowerShell: recovering from corrupt empty *.nupkg files after a disk was accidentally full during update.

Here are some xargs equivalency examples:
