  • Simple Video Surveillance by email

    This takes a picture (with the web cam) every 5 minutes, and send the picture to your e-mail. Some systems support mail -a "References: " so that all video surveillance emails are grouped in a single email thread. To keep your inbox clean, it is still possible to filter and move to trash video surveillance emails (and restore these emails only if you really get robbed!) For instance with Gmail, emails sent to me+trash@gmail.com can be filtered with "Matches: DeliveredTo:me+trash@gmail.com" Show Sample Output

  • encode image to base64 and copy to clipboard

  • Copy a file over SSH without SCP

    cat didn't seem to work with binaries to well for me, the above command seemed to do the trick. Opps should be pointed out its going through a "hop" box (which is why I was searching here in first place), only need the last bit (after the -t) if doing it directly from one box to another...

  • Copy a file over SSH without SCP

    I have come across multiple situations where I could only get to a server from a very restrictive bounce point which would not allow file transfers. I was able to uuencode a file, copy the output to a text file over putty, and then uudecode the file to transfer it. This works with any kind of file. Show Sample Output

Go up multiple levels of directories quickly and easily.
This is a kind of wrapper around the shell builtin cd that allows a person to quickly go up several directories. Instead of typing: cd ../.. A user can type: cd ... Instead of: cd ../../.. Type: cd .... Add another period and it goes up four levels. Adding more periods will take you up more levels.
