Database of Common Telnet commands for Linux based STB's

[silverfox0786]

Hi guys here i am going to try a formulate a general Telnet command database for LInux boxes so that all commands are in one place.

Anybody can add a command here but please keep it to commands and not disscussions or command help requests

Please remember to also put in the commands use and a small description of some sort just so we know what that command is used for

If when navigating the forum you come accross a post with command posted then please paste it here as well with its common use

Thanks Guys...

Disclamer: this has been used by a few users without error but i recomend getting a backup of your image first just incase you get green screen after.

Thanks to pooface:

ok so it's been a while since this thread was updated so here goes.

init 3 = reboots enigma or wakes enigma from a sleeping state
init 4 = kills enigma or puts it to sleep, This is a important command for use when working with processes that are held in live memory such as bouquet files and EPG.dat files.
init 6 = performs a shutdown and reboot of the whole receiver not just enigma,
shutdown -r now = same as the init 6 command

Screen Grabs/Dumps
grab -o -p /tmp/grab.png [change grab to the file name you want it to be] shows OSD only.
grab -d -p /tmp/grab.png [change grab to the file name you want it to be] shows OSD with channel.

your png files will be sent to /tmp retreive via FTP
