Live stream a remote desktop over ssh using only ffmpeg

Play with the framerate option '-r' to scale back bandwidth usage. The '-s' option is the captured screan area, not the rescaled size. If you want to rescale add a second '-s' option after '-i :0'. Rescaling smaller will also decrease bandwidth.

Copy files and directories from a remote machine to the local machine

This command will copy files and directories from a remote machine to the local one. Ensure you are in the local directory you want to populate with the remote files before running the command. To copy a directory and it's contents, you could: ssh user@host "(cd /path/to/a/directory ; tar cvf - ./targetdir)" | tar xvf - This is especially useful on *nix'es that don't have 'scp' installed by default.

Pull up remote desktop for other than gnome/kde eg fluxbox

If the remote doesn't export its desktop (eg fluxbox, blackbox etc) then you need to run a x11vnc server there and a vncviewer at the local end. This command does the lot for you - it assumes that you can 'ssh' to the box without a password and that x11vnc is installed at the remote end.
This is sample output - yours may be different.

rdp() { ssh $1 sh -c 'PATH=$PATH:/usr/local/bin; x11vnc -q -rfbauth ~/.vnc/passwd -display :0' & sleep 4; vncviewer $1:0 & }

The proper way to read kernel messages in realtime.

Convert control codes to visible Unicode Control Pictures

Converts control codes and spaces (ASCII code ≤ 32) to visible Unicode Control Pictures, U+2400 ? U+2420. Skips \n characters, which is probably a good thing.

Join lines

Even shorter. Stolen from comment posted by eightmillion.

Given process ID print its environment variables

intercept stdout/stderr of another process

Convert seconds into minutes and seconds

This is a very simple way to input a large number of seconds and get a more useful value in minutes and seconds.

Random Number Between 1 And 256

It takes a byte from /dev/random whose source is the kernel entropy pool (better source than other solutions).

Broadcast your shell thru UDP on port 5000

Better solution in case of many clients, imo.

Kill process by pid

To kill a process in windows by using the PID. Change 10728 to the PID of the process you want to kill.

repeat a command every one second

Short method of "while x=0; do foo ; sleep 1 ; done"
