I was trying to run a command with at, but with no success…
I guess that at is primary designed to run shell scripts…. BUT if want to run system command?

echo "ls -la" | at now + 1 minutes

It will run the ls -la from now plus one minute 🙂

f*ck!

i’v been struggling with avconv, exec, chown and all that sh*ts this last two days!
’cause i was trying to preform a  exec to avconv to create some screencaps and the command was  in two lines…

echo $avconScreenScroll = 'avconv -i '.$destFolder.'/' . $dataVideos['videos'][$key]['videoFilename'] . '
 -vsync 1 -s 150x100 -qscale 1 -r 1 -an -y ' . $screencapsDir . '/scroll/img%03d.jpg';
 exec($avconScreenScroll);

exec() executes an external program

shell_exec() executes a command via shell and returns the output as a string

To limit CPU usage of the process called avconv to 70%, enter:

cpulimit -e avconv -l 30

To limit CPU usage of the process to 70% by using its PID, enter:

cpulimit -p 6969 -l 70

If the process isn’t running cpulimit will wait for it.

CONFIGURE

Create a single file for your project to describe the type of machine you want, the software that needs to be installed, and the way you want to access the machine. Store this file with your project code.

WORK

Run a single command — “vagrant up” — and sit back as Vagrant puts together your complete development environment. Say goodbye to the “works on my machine” excuse as Vagrant creates identical development environments for everyone on your team.

Just bought one of those…
a old rack server from DELL just to have fun with it.
