A very tiny bash script to display images

[grondilu]

This bash script only requires ImageMagick (for convert), and GNU Coreutils (for base64 and tr):

function icat() {
  convert "${1:-}" png:- |
  base64 -w64 - |
  sed -e '
    $!s/^/m=1;/;
    $ s/^/m=0;/;
    1 s/^/a=T,f=100,t=d,/;
    ' -e "s/^/\x1B_G/; s/$/\x1B\\\\/" |
  tr -d '\n'
}

Why -w 64? The chunk size limitation is 4096. And see here for a script that does not need either tr or sed https://sw.kovidgoyal.net/kitty/graphics-protocol/#a-minimal-example to transmit PNG files with BASH Also note that -w is a GNU extension to base64 its not present on BSD machines/macOS.

Not sure why I used 64, I think I had to divide 4096 by 64 at some point for some reason.

I found your bash script a bit convoluted so I wanted something cleaner.

I personally don't mind using GNU extensions, but I understand this is a portability issue.
