Read the B<Reader's guide> below if you are new to GNU B<parallel>.
GNU B<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 B<parallel> can then split the input into
blocks and pipe a block into each command in parallel.

If you use xargs and tee today you will find GNU B<parallel> very easy to

you write loops in shell, you will find GNU B<parallel> may be able to
replace most of the loops and make them run faster by running several

For short jobs with little output B<par> is 20% faster than GNU
B<parallel> and 60% slower than B<xargs>.

B<fd> does not support composed commands, so commands must be wrapped
in B<sh -c>.
It buffers output in RAM.
It buffers output in RAM.
It only takes file names from the filesystem as input (similar to B<find>).

=head2 DIFFERENCES BETWEEN lateral AND GNU Parallel
B<lateral> is very similar to B<sem>: It takes a single command and
runs it in the background. The design means that output from parallel
running jobs may mix. If it dies unexpectly it leaves a socket in
~/.lateral/socket.PID.
B<lateral> deals badly with too long command lines. This makes the
B<lateral> server crash:
lateral run echo `seq 100000| head -c 1000k`
Any options will be read by B<lateral> so this does not work
(B<lateral> interprets the B<-l>):
lateral run ls -l
Composed commands do not work:
lateral run pwd ';' ls
Functions do not work:
myfunc() { echo a; }
export -f myfunc
lateral run myfunc
Running B<emacs> in the terminal causes the parent shell to die:
echo '#!/bin/bash' > mycmd
echo emacs -nw >> mycmd
chmod +x mycmd
lateral start
lateral run ./mycmd
Here are the examples from https://github.com/akramer/lateral with the
corresponding GNU B<sem> and GNU B<parallel> commands:
1$ lateral start
1$ for i in $(cat /tmp/names); do
1$ lateral run -- some_command $i
1$ done
1$ lateral wait
1$
1$ for i in $(cat /tmp/names); do
1$ sem some_command $i
1$ done
1$ sem --wait
1$
1$ parallel some_command :::: /tmp/names
2$ lateral start
2$ for i in $(seq 1 100); do
2$ lateral run -- my_slow_command < workfile$i > /tmp/logfile$i
2$ done
2$ lateral wait
2$
2$ for i in $(seq 1 100); do
2$ sem my_slow_command < workfile$i > /tmp/logfile$i
2$ done
2$ sem --wait
2$
2$ parallel 'my_slow_command < workfile{} > /tmp/logfile{}' \
::: {1..100}
3$ lateral start -p 0 # yup, it will just queue tasks
3$ for i in $(seq 1 100); do
3$ lateral run -- command_still_outputs_but_wont_spam inputfile$i
3$ done
3$ lateral config -p 10; lateral wait # command output spam can commence
3$
3$ for i in $(seq 1 100); do
3$ echo "command inputfile$i" >> joblist
3$ done
3$ parallel -j 10 :::: joblist
3$
3$ echo 1 > /tmp/njobs
3$ parallel -j /tmp/njobs command inputfile{} \

=head2 DIFFERENCES BETWEEN with-this AND GNU Parallel
The examples from https://github.com/amritb/with-this.git and the
corresponding GNU B<parallel> command:
with -v "$(cat myurls.txt)" "curl -L this"
parallel curl -L ::: myurls.txt
with -v "$(cat myregions.txt)" \
"aws --region=this ec2 describe-instance-status"
parallel aws --region={} ec2 describe-instance-status \
:::: myregions.txt
with -v "$(ls)" "kubectl --kubeconfig=this get pods"
ls | parallel kubectl --kubeconfig={} get pods
with -v "$(ls | grep config)" "kubectl --kubeconfig=this get pods"
ls | grep config | parallel kubectl --kubeconfig={} get pods
with -v "$(echo {1..10})" "echo 123"
parallel -N0 echo 123 ::: {1..10}
Stderr is merged with stdout. B<with-this> buffers in RAM. It uses 3x
the output size, so you cannot have output larger than 1/3rd the
amount of RAM. The input values cannot contain spaces. Composed
commands do not work.
B<with-this> gives some additional information, so the output has to
be cleaned before piping it to the next command.
