rename a section of a filename, i. e. example.1.{txt,conf,db} or 12345.1.{wav,ogg,mp3} and

change the 1 to a 2 in the filename while preserving the rest of it.

$ zmv -n '(.)(<->)(.[^.]#)' '$1$(($2+1))$3' # would rename x.0001.y to x.2.y. $ zmv -n '(.0#)(<->)(.[^.]#)' '$1$(($2+1))$3'

Rename files to lower case

$ zmv '*' '${(L)f}'

serially all files (foo.foo > 1.foo, fnord.foo > 2.foo, ..)

$ autoload zmv

SimpleNote to Markdown

This script converts JSON file from Simplenote Export web service into individual Markdown files.

It's nothing fancy, first argument is the JSON file, second argument is directory to write the notes to. The note files are named by using the first 60 characters (or a little more, up to a full word) of the first line of the note, stripped of any characters outside of letters, simple dash, underscore, brackets, space, single quote, and plug and equal signs.

Tags are stored on the bottom of the note on a line starting with "TAGS:", and the SimpleNote note ID/key as a "KEY:" line.

A simple Ghostscript command to merge two PDFs in a single file is shown below:

gs -dNOPAUSE -sDEVICE=pdfwrite -sOUTPUTFILE=combine.pdf -dBATCH 1.pdf 2.pdf

Install Ghostscript:

Type the command sudo apt-get install ghostscript to download and install the ghostscript package and all of the packages it depends on.

	Usage:
	morphagene_onset.py -w <inputwavfile> -o <outputfile> -s <splicecount>

	Use the Superflux onset detection algorithm with backtracking to generate
	splice locations.
	Use these splice locations with a converted WAV (to 32-bit float / 48000Hz)
	to make Morphagene reels.
