bashumerate — iterate over files, lines, ranges, or lists with a consistent {} syntax. No for loops, no find -exec, no xargs flags to remember. enumerate -f '*.sh' -- wc -l {} enumerate -L a b c -- 'echo {}' Under 150 lines of bash, pluable sources, NUL-safe. https://github.com/wallach-game/bashumerate
