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