memory management, cron

Create the memcheck.sh script that will write a mem.log file with the data, and agnuplot script that will plot it.

[gist id=1201994]

Then set up a cron job.  First, set the editor to something functional:

export EDITOR=vi

then, crontab -e to edit the cron table.  Add this line to run the command every 2 minutes (see wikipedia entry for quick intro), and plot it every 15 minutes:

*/2 * * * * /home/cboettig/./memcheck.sh
*/15 * * * * gnuplot /home/cboettig/memplot.gnu

See resulting plot.
