Admittedly a nice tool for ruby users. But for 'grep/sed/awk' users? Forget and learn a new syntax? I don't quite see the benefit of pru from the examples for 'grep/sed/awk' users, memory and speed issues put aside. Even the 'number of files by date' can be realized with, eg., awk: ls -al |awk '{++a[$6]} END {for (i in a) printf "%s: %d\n", i, a[i]}'
