nmap scan hosts for IP, MAC Address and device Vendor/Manufacturer

In the field, I needed to script a process to scan a specific vendor devices in the network. With the help of nmap, I got all the devices of that particular vendor, and started a scripted netcat session to download configuration files from a tftp server. This is the nmap loop (part of the script). You can however, add another pipe with grep to filter the vendor/manufacturer devices only. If want to check the whole script, check in http://pastebin.com/ju7h4Xf4 Show Sample Output

```
10.0.0.1 AA:BB:CC:DD:EE:FF (Vendor)
10.0.0.2 BB:CC:DD:EE:FF:AA (Manufacturer)
10.0.0.3 FF:FF:FF:FF:FF:FF (Unknown)

simulates the DOS tree command that you might be missing on your Mac or Linux box

NOT MINE! Taken from hackzine.com blog. It creates a tree-style output of all the (sub)folders and (sub)files from the current folder and down(deeper) Quoting some of hackzine's words "Murphy Mac sent us a link to a handy find/sed command that simulates the DOS tree command that you might be missing on your Mac or Linux box. [..split...] Like most things I've seen sed do, it does quite a bit in a single line of code and is completely impossible to read. Sure it's just a couple of substitutions, but like a jack in the box, it remains a surprise every time I run it." Show Sample Output

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Emptying a text file in one shot

% = buffer d = delete

List all NPM global packages installed

Send pop-up notifications on Gnome

The title is optional. Options: -t: expire time in milliseconds. -u: urgency (low, normal, critical). -i: icon path. On Debian-based systems you may need to install the 'libnotify-bin' package. Useful to advise when a wget download or a simulation ends. Example: $ wget URL ; notify-send "Done"

Cleanup Python bytecode files

This command will erase all bytecode versions of Python modules under the current directory.

Find usb device in realtime

Using this command you can track a moment when usb device was attached.

Kill all Zombie processes (Guaranteed!)

It identifies the parents of the Zombie processes and kill them. So the new parent of orphan Zombies will be the Init process and he is already waiting for reaping them. Be careful! It may also kill your useful processes just because they are not taking care and waiting for their children (bad parents!).

Remove newlines from output

Pipe any output to "grep ." and blank lines will not be printed.

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Reconnect to screen without disconnecting other sessions

Have your screen session running in multiple places. (warning, things start to look weird if the terminal windows have different dimensions)

Dump sqlite database to plain text format

If you want edit your sqlite database in any uft8 supported editor, you can dump whole sqlite database to plain text.
