Zsh: sort globs in natural order with the (n) glob qualifier

Globs sort filenames character by character, so numbered files often come out in a surprising order, with 10 before 2. Zsh has a neat fix for this: the n glob qualifier, which applies a “natural” sort, treating any run of digits as a number rather than a string of characters. I found this feature useful when building a PDF from multiple files.n I exported my multi-page document from Inkscape to one PNG per page, named Page 1.png, Page 2.png, and so on. I then stitched them into a single PDF with ImageMagick: $ magick *.png document.pdf But when I opened document.pdf, the pages were jumbled: page 10 came straight after page 1. That made no sense! To debug, I checked what the glob expanded to, using print -l to print each match on its own line: $ print -l *.png Page 1.png Page 10.png Page 11.png Page 12.png Page 2.png Page 3.png ... There it was: Page 10.png came before Page 2.png, because the character 1 sorts before 2. Adding the n glob qualifier makes Zsh sort numbers by their…
