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.

Alternative way to generate an XKCD #936 style 4 word password usig sed

This is what I came up to generate XKCD #936 style four-word password. Since first letter of every word is capitalized it looks a bit more readable to my eyes. Also strips single quotes. And yes - regex is a bit of a kludge, but that's the bes i could think of.

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.

Function to output an ASCII character given its decimal equivalent

Url Encode

Returns URL Encoded string from input ($1).

Paste hardware list (hwls) in html format into pastehtml.com directly from console and return URI.

In this Linux box i need to become root to get the complete hardware list, so either become root before or call it with sudo as i did, your choice.

Define words and phrases with google.

This function takes a word or a phrase as arguments and then fetches definitions using Google's "define" syntax. The "nl" and perl portion isn't strictly necessary. It just makes the output a bit more readable, but this also works: $define(){ local y="$@";curl -sA"Opera" "http://www.google.com/search?q=define:${y// /+}"|grep -Po '(?/dev/null;}

Equivalent to ifconfig -a in HPUX

Command is properly working on HP-UX 11.31
