Switch all connected PulseAudio bluetooth devices to A2DP profile

Tries to switch all audio devices to the A2DP profile for optimal sound quality. Useful for bluetooth speakers and headphones that always power up in HSP/HFP mode. Note however that this command is only a shorthand for the GUI, so it cannot fix stubborn BT controllers that leave your device stuck in HSP mode until a manual re-coupling.

Detect illegal access to kernel space, potentially useful for Meltdown detection

Based on capsule8 agent examples, not rigorously tested

Join lines

It's works only when you replace '\n' to ONE character.

Encode/Decode text to/from Base64 on a Mac w/out Mac Ports

I have a mac, and do not want to install mac ports to get the base64 binary. Using openssl will do the trick just fine. Note, to decode base64, specify a '-d' after 'base64' in the command. Note also the files base64.decoded.txt and base64.encoded.txt are text files.

Fire CMD every time FILE (or directory) is updated (on *BSD)

Rename files in batch

Nicely display mem usage with ps

Extract IPv4 addressess from file

create and md5 sum of your password
