Faster lolcat, since written in c (even beats c-lolcat). Features: -About a fucking LOT faster (more below) -Handles lines with length > terminal width better -Always uses truecolor On my system it gives the following speedup: $ time dmesg | lolcat -t ... (some floating point errors visible) real 1.104s user 0.841s sys 0.276s $ time dmesg | clolcat ... (no floating point errors visible) real 0.113s user 0.022s sys 0.012s When measuring performance keep in mind that on some systems (espicially with nouveau instead of proprietary graphic drivers) the bottleneck might be overhead from outputting to a terminal.
