<title>DESCRIPTION</title>
<para><command>mispipe</command> pipes two commands
together like the shell does, but unlike piping in the
shell, which returns the exit status of the last command;
when using mispipe, the exit status of the first command
is returned.
</para>
<para>
Note that some shells, notably <command>bash</command>,
do offer a pipefail option, however, that option does not
behave the same since it makes a failure of any command in
the pipeline be returned, not just the exit status of the
first.
</para>
</refsect1>
<refsect1>
<title>EXIT STATUS</title>
<para>The exit status of the first command. If the process
terminated abnormally (due to a signal), 128 will be added
to its exit status.</para>
