<oerjan> le/rn tmp//tmp/ is a directory for files that are not worth saving in HackEgo history, but which should still survive a single command. Note that it interacts funnily with HackEgo\'s lock and re-run commit check: files can disappear if you don\'t know what you\'re doing. Basically, don\'t modify files inside and outside tmp/ in the same HackEgo command.

#!/bin/bash
interp="$1"; script="$2"; shift 2; if [ "$#" -eq 1 ]; then printf '%s\n' "$1"; elif [ "$#" -eq 0 ]; then cat; fi | { shift; $interp "$script" "$@"; }
