<P>Causes 7-Zip to write output data to stdout (standard output stream).</P>
<H4>Syntax</H4>
<PRE class="syntax">
-so
</PRE>
<P>If the -so switch is used with the command that creates archive, it works only
with some archive formats: xz, gzip, bzip2 and tar.</P>
<H4>Examples</H4>
<PRE class="example">
7z x archive.gz -so > Doc.txt
</PRE>
<P>decompresses <SPAN class="filename">archive.gz</SPAN>
archive to output stream and then redirects that stream to
<SPAN class="filename">Doc.txt</SPAN> file.</P>
<PRE class="example">
7z a dummy -tgzip -so Doc.txt > archive.gz
</PRE>
<P>compresses the <SPAN class="filename">Doc.txt</SPAN> file to the 7-Zip standard
output stream and writes that stream to
<SPAN class="filename">archive.gz</SPAN> file.</P>
