One-liner fetches favicon from the network, converts it to base64, and prints an HTML link tag with favicon data URL. Use with discretion, favicons may be legally possessed. It's great fun to jazz local scripts and documents.

Single line data and output:
perl -MHTTP::Tiny -MMIME::Base64 -e 'print qq~<link href="data:image/x +-icon;base64,~, encode_base64(HTTP::Tiny->new->get($ARGV[0])->{conten +t},""), qq~" rel="icon" type="image/x-icon">~||die"something went wro +ng"' https://perlmonks.org/favicon.ico
Multi-line data and output:
perl -MHTTP::Tiny -MMIME::Base64 -e 'print qq~<link href="data:image/x +-icon;base64,\n~, encode_base64(HTTP::Tiny->new->get($ARGV[0])->{cont +ent},"\n"), qq~" rel="icon" type="image/x-icon">\n~||die"something w +ent wrong"' https://www.perl.com/favicon.ico
Single line data and output as a script:
