@MyNewMinuteNewt @robdaemon @theruran Back in 32bit PC days, I loved #asmutils https://asm.sourceforge.net/asmutils.html replacement for standard UN*X utilities. E.g. its tar(1) is 1185 bytes, compared to 520K (+~2MB of shared libs) of your Debian GNU tar. Its sh (with command line completion) is self-contained in 4700 bytes, compared to 1.3MB for bash, or 123K for (tiny!) dash (both of which need that ~2MB shared lib too!) . Blows your mind!
Also, beautiful tutorial on #leansoftware: http://www.muppetlabs.com/~breadbox/software/tiny/teensy.html
