Find running binary executables that were not installed using dpkg

This helped me find a botnet that had made into my system. Of course, this is not a foolproof or guarantied way to find all of them or even most of them. But it helped me find it.

Tags: Debian dpkg PATH

find files in $PATH that were not installed through dpkg

OS: Debian based (or those that use dpkg)

Equivalent to doing a dpkg -S on each file in $PATH, but way faster.

May report files generated though postinstall scripts and such. For example . It will report /usr/bin/vim .. which is not not a file installed directly by dpkg, but a link generated by alternatives hooks

Makes a Zenity select list based on entries in your wpa_supplicant.conf

If you still connect to your wireless access point manually and need to use wpa_supplicant, the above fu will grep all of the known SSID from your wpa_supplicant.conf file, present it in a Zenity list and return the SSID name you choose. I've wrapped this command in to a bash script that then up's the interface, associates and autenticates. Saves me from using NetworkManager ;)

Edit all files found having a specific string found by grep

Edit all files found having a specific string found by grep

The grep switches eliminate the need for awk and sed. Modifying vim with -p will show all files in separate tabs, -o in separate vim windows. Just wish it didn't hose my terminal once I exit vim!!
