|
|
'' GNU Parallel is a shell tool for executing jobs in parallel. 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, or a list of tables.
|
|
|
|
If you use xargs today you will find GNU Parallel very easy to use.
|
|
If you write loops in shell, you will find GNU Parallel may be able
|
|
to replace most of the loops and make them run faster by running
|
|
jobs in parallel. If you use ppss or pexec you will find GNU
|
|
Parallel will often make the command easier to read.
|
|
|
|
GNU Parallel makes sure output from the commands is the same output
|
|
as you would get had you run the commands sequentially. This makes
|
|
it possible to use output from GNU Parallel as input for other
|
|
programs.
