|

GNU Parallel is a shell tool for executing jobs in parallel using one
|
||||
or more computers. A job is typically 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.

input is a list of files, a list of hosts, a list of users, a list of
