The following tools are available as part of the filo package:
groupBy â€“ mimics the â€œgroupByâ€ clause in database systems.
shuffle â€“ randomize the order of lines in a file.
stats â€“ computes descriptive statistic on a given column of a tab-delimited file or stream.
Because their name is too generic, â€˜shuffleâ€™ and â€˜statsâ€™ are relocated in /usr/lib/filo.
