-.SH "NAME"
-parallel \- run programs in parallel
-.SH "SYNOPSIS"
-.HP \w'\fBparallel\fR\fB\-\-\fR\ 'u
-\fBparallel\fR [options] [command]\fB\-\-\fR [argument\ \&.\&.\&.]
-.HP \w'\fBparallel\fR\fB\-\-\fR\ 'u
-\fBparallel\fR [options]\fB\-\-\fR [command\ \&.\&.\&.]
-.SH "DESCRIPTION"
-.PP
-\fBparallel\fR
-runs the specified command, passing it a single one of the specified arguments\&. This is repeated for each argument\&. Jobs may be run in parallel\&. The default is to run one job per CPU\&.
-.PP
-If no command is specified before the \-\-, the commands after it are instead run in parallel\&.
-.SH "OPTIONS"
-.PP
-\fB\-j maxjobs\fR
-.RS 4
-Use to limit the number of jobs that are run at the same time\&.
-.RE
-.PP
-\fB\-l maxload\fR
-.RS 4
-Wait as needed to avoid starting new jobs when the system\*(Aqs load average is not below the specified limit\&.
-.RE
-.PP
-\fB\-i\fR
-.RS 4
-Normally the command is passed the argument at the end of its command line\&. With this option, any instances of "{}" in the command are replaced with the argument\&.
-.RE
-.PP
-\fB\-n\fR
-.RS 4
-Number of arguments to pass to a command at a time\&. Default is 1\&. Incompatible with \-i
-.RE
-.SH "EXAMPLE"
-.PP
-.HP \w'\fBparallel\ sh\ \-c\ "echo\ hi;\ sleep\ 2;\ echo\ bye"\ \-\-\ 1\ 2\ 3\fR\ 'u \fBparallel sh \-c "echo hi; sleep 2; echo bye" \-\- 1 2 3\fR
-.PP
-This runs three subshells that each print a message, delay, and print another message\&. If your system has multiple CPUs, parallel will run some of the jobs in parallel, which should be clear from the order the messages are output\&.
-.PP
-.HP \w'\fBparallel\ \-j\ 3\ ufraw\ \-o\ processed\ \-\-\ *\&.NEF\fR\ 'u \fBparallel \-j 3 ufraw \-o processed \-\- *\&.NEF\fR
-.PP
-This runs three ufraw processes at the same time until all of the NEF files have been processed\&.
-.PP
-.HP \w'\fBparallel\ \-j\ 3\ \-\-\ ls\ df\ "echo\ hi"\fR\ 'u \fBparallel \-j 3 \-\- ls df "echo hi"\fR
-.PP
-This runs three independent commands in parallel\&.
-.SH "EXIT STATUS"
-.PP
-Its exit status is the combination of the exit statuses of each command ran, ORed together\&. (Thus, if any one command exits nonzero,
-\fBparallel\fR
-as a whole will exit nonzero\&.)
