Check These Out
order the files by modification (thanks stanishjohnd) time, one file per output line and filter first 10
I wanted all the 'hidden' .flv files from the http link in the command line; wget seemed appropriate, fed with output from lynx, grep the flv files and the normalised via sed (to remove the numeric bullet). Similar to the 'Grab mp3 files' fu. Replace link with your own, grep arg with something more interesting ;) See here for something along the same lines...

Hope you find it useful! Improvements welcome, naturally.

Rest is self-explanatory.
I just started out with Arch - so if there is any better/standard method to achieve the same - please suggest.
Found the same command for zsh in http://www.davidpashley.com/articles/xterm-titles-with-bash.html - changed it a bit so that the behaviour is the same
The Piano Phase piece, by Steve Reich is a minimalist composition which is played on two pianos played at slightly different tempos, a task that's very difficult to accomplish by human players. The auditive effects produced by the cell displacement produce beautiful patterns.
See https://en.wikipedia.org/wiki/Piano_Phase . My rendered version: https://ydor.org/SteveReich/piano_phase.mp3
Requires sox to be installed on the system.
There are multiple videos on youtube showing different approaches and experiences to this interpretation. There is also a synthesized version.
Even if Bash can behave as a powerful pianist, a simple threaded version leaves full room to several time glitches and even negative displacements, the same issues that human pianists experience when playing the piece. The older the computer, the better the chaos added to the result due to the CPU load. Apparently that's the reason Steve Reich composes pieces such as this.
Without further ado, please give a warm welcome to the Bash minimalist player on synthesized two-threaded pianos. Please turn off your cellphones.
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
Short method of "while x=0; do foo ; sleep 1 ; done"
