A simple script to batch convert images to telegram sticker accepted format, dimensions & file size

telegram-stickers-converter.sh

#!/bin/bash

# requiements:
# - imagemagick
# - pngquant
# - npm and renamer package


# convert jpg files to png
for f in *.jpg; do
    echo "Processing $f"
    n="${f%.*}"
    convert $f "$n.png"
done

# resize png files to 512x512
for f in *.png; do
    echo "Processing $f"
    convert $f -resize 512x512 "$f"
done

# lossy optimise pngs
for f in *.png; do
    echo "Processing $f"
    pngquant $f
done

# clear the directory and move out optimized files only

rm *.jpg
if [ ! -d "done" ]; then
    mkdir "done"
fi
mv *-fs8* "done/"
renamer -f "-fs8" "done/*.png"
rm *.png

echo "All done!"

So, I tried using this script, and it created a directory "done" and started changing all the files.....

Then immediately deleted every file in the directory I ran it in, and "done" is empty. Did I do something wrong?

yo this script sucks ass, it deleted all of my memes

@Elbobburrito @ottersarecool sorry to hear that.
The intended behavior here is:

1. input is a directory with PNG and/or JPG files.
2. the script converts all JPGs to PNGs, then resizes and optimizes (lossy) the PNGs.
3. processed PNGs are put to "done" folder and source files are removed

I intended it to work such way - it suited my workflow. Maybe there should be a warning before starting the script or smth like that.
