  • Most of the commands require the jpegs a certain format, not this, it just follows alphabetical order. The same order you follow if you do "ls -lisah" from top to bottom, top frame is first, bottom is last... This goes perfectly with a webcam timelapse... I have just the script for it: http://www.kossboss.com/linux---app-script---timelapse---capush Show Sample Output

  • Where filein is the source file, destination.com is the ssh server im copying the file to, -c arcfour,blowfish-cbc is selecting the fastest encryption engines, -C is for online compressions and decompression when it comes off the line - supposed to speed up tx in some cases, then the /tmp/fileout is how the file is saved...

log your PC's motherboard and CPU temperature along with the current date
Uses the data in the /proc system, provided by the acpid, to find out the CPU temperature. Can be run on systems without lm-sensors installed as well.

Print process run time, average CPU usage, and maximum memory usage on exit
Bash has a built-in time command which provides less functionality than the real time command. Thus we reference /usr/bin/time directly. Since the command isn't very easy to remember you could alias it to something like "cputime" or even just "time".
