“mplayer -dumpaudio GummyBearSong.avi -dumpfile gummybear.mp3”
Where:
“GummyBearSong.avi” is the source video, in the example above it was 30 MB
“gummybear.mp3” is the output audio file (in mp3 format), was about 3 MB in size
Another method that worked flawlessly with an MP4 file is using ffmpeg:
ffmpeg -i SOURCE.mp4 -vn -acodec libmp3lame OUTPUT.mp3
In Gnome, you can force any application to go full screen;
Open System=>Preferences=>Keyboard shortcuts
Under “Window Management” assigne any key combinations such as “CTL+SHIFT+F” for “Toggle Fullscreen mode”.
Open any application (firefox, eclipse, ….) and press “CTRL + SHIFT + F”, the program will goes in full screen mode.
example bash file:
save the following in a file called print.sh
#!/bin/bash
echo “$@”
and then :
chmod +x print.sh
./print.sh hello world
Note that, all the parameters you pass to print.sh will be passed to echo, this because of “$@”
“list sessions for login user_name“
“sudo apt-get install chatplus chatplus-server”
Just Some Techie Notes!
