= Presentation of GNU Parallel =

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

If you use xargs and tee today you will find GNU parallel very easy to
use as GNU parallel is written to have the same options as xargs. 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 several
jobs in parallel.

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.


= Installation =

Installation of GNU Parallel is a simple as:

  ./configure && make && make install

If you are not root you can install in ~/bin and ~/share:

  ./configure --prefix=$HOME && make && make install

After this you should be able to do:

  parallel traceroute ::: foss.org.my gnu.org freenetproject.org

This will run traceroute to 3 different hosts in parallel and print
the output when the traceroutes are done.
