Delete recursively only empty folders on present dir

back ssh from firewalled hosts

host B (you) redirects a modem port (62220) to his local ssh. host A is a remote machine (the ones that issues the ssh cmd). once connected port 5497 is in listening mode on host B. host B just do a ssh 127.0.0.1 -p 5497 -l user and reaches the remote host'ssh. This can be used also for vnc and so on.

Connect-back shell using Bash built-ins

Connect-back shell using Bash built-ins. Useful in a web app penetration test, if it's the case of a locked down environment, without the need for file uploads or a writable directory. -- /dev/tcp and /dev/udb redirects must be enabled at compile time in Bash. Most Linux distros enable this feature by default but at least Debian is known to disable it. -- http://labs.neohapsis.com/2008/04/17/connect-back-shell-literally/

copy root to new device

Clone a root partition. The reason for double-mounting the root device is to avoid any filesystem overlay issues. This is particularly important for /dev. Also, note the importance of the trailing slashes on the paths when using rsync (search the man page for "slash" for more details). rsync and bash add several subtle nuances to path handling; using trailing slashes will effectively mean "clone this directory", even when run multiple times. For example: run once to get an initial copy, and then run again in single user mode just before rebooting into the new disk. Using file globs (which miss dot-files) or leaving off the trailing slash with rsync (which will create /mnt/target/root) are traps that are easy to fall into.

Find usb device in realtime

Stream YouTube URL directly to mplayer.

Streams youtube video with v=ID directly into the mplayer. If exists, it uses the HD-quality stream. If you don't want to watch it in HD-quality, you can use the shorter form: $ID=52DnUo6wJto; mplayer -fs $(echo "http://youtube.com/get_video.php?&video_id=$ID$(wget -qO - 'http://youtube.com/watch?v='$ID | perl -ne 'print $1."&asv=" if /^.*(&t=.*?)&.*$/')")
