Gnu parallel

Video molto carino di Ole Tange che spiega l’uso di Gnu Parallel.

GNU parallel is a shell tool for executing jobs in parallel using one or more computers. A job can be a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. A job can also be a command that reads from a pipe. GNU parallel can then split the input and pipe it into commands in parallel.

Ossia quello che prima bisognava fare con xargs|bash ora si può fare molto, molto meglio.
