Bash script for resizing images

Resize

Use the finder preference > advanced > show all filename extensions

Really make sure you are in the right directory before running these scripts or it can change a lot of file

This is kinda a ridiculous thing I wanted to do thats overkill but I wanted to learn command line scripts and do a few specific things with image resizing.

Careful to make sure this is in the right spot

sh ~/Developer/resize/resize.sh

things to do

• check how big something in an array is

The Linux Documentation Project

• fi the end of an if statement is backwards if.
• sips this is the main tool we are using
  • -g = --getProperty
  • https://ss64.com/osx/sips.html

Theres some nice things like do ends in done. if ends in fi.

-p fails silently? https://superuser.com/questions/165157/what-does-the-p-flag-do-in-mkdir-p The -p flag will create nested directories, but only if they don't exist already.

we can only do one type of image per folder

maybe I need to remove all folders before I start work?

Im not currently renaming the orignal image but whatever

• loop through each format at a time, if known do it, if common list of known to not work .txt etc dont and ask about unknown files

• create the html document to accompany at then end

• drag and drop, but thats less of a proprity

  • if one file then create a folder to hold the images after

• have a quiet and verbouse readout

• check if I have the webp and png compression algerithms on the system before running them or do they fail silently?

• take pieces out into seperate files if I can. outside the loops things like name change

• document the png compression

• can I push the jpegs to jpeg mini? that was manual

• maybe replace all . in short filenames before the extension and replace them with - this happens automatically in screenshots, doesnt seem to cause issues but it could

• there was something about putting it in the dock but I cant remeber what it did and how

• for png and webp does it become a node thing?

• if a file doesnt show an extension it gets it twice in the end, macs love not showing the extensions that are there

• reset the variables to logical order I go up and down in the letters

• if i dont like double dashes that much and I know how to make them and delete them I can just do that at the end? 🚨 except for when they are already in files?

• should i also rename the original file to get a width x height? I can do a check with double dashes if i can figure out the pull them from files

• auto generate the array of sizes by division or how much less each time, its doing all the work the more the better?

• I need to be able to order the arrays
