<p> Hello.</p>
<p> </p>
<p> When I have installed my rpm package from some YUM repository with simple PERL script:</p>
<p></p>
<p>#!/usr/bin/perl</p>
<p>$| = 1;</p>
<p>open (CMD, "yum -y install mypackage 2>&1 |");</p>
<p>while (<CMD>)</p>
<p>{</p>
<p> print "$_";</p>
<p>}</p>
<p>close (CMD);</p>
<p></p>
<p> Output of script is displayed piece by piece (it is buffering). Output postinstall script is displayed before output of information about package's installation. See script output below. </p>
<p> But a<a name="b"></a>f<a name="b"></a>t<a name="b"></a>e<a name="b"></a>r<a name="b"></a> <a name="b"></a>i<a name="b"></a>n<a name="b"></a>s<a name="b"></a>t<a name="b"></a>a<a name="b"></a>l<a name="b"></a>l<a name="b"></a>a<a name="b"></a>t<a name="b"></a>i<a name="b"></a>o<a name="b"></a>n<a name="b"></a> <a name="b"></a>o<a name="b"></a>f<a name="b"></a> <a name="b"></a>t<a name="b"></a>h<a name="b"></a>e<a name="b"></a> <a name="b"></a>p<a name="b"></a>a<a name="b"></a>c<a name="b"></a>k<a name="b"></a>a<a name="b"></a>g<a name="b"></a>e<a name="b"></a> <a name="b"></a>f<a name="b"></a>r<a name="b"></a>o<a name="b"></a>m<a name="b"></a> <a name="b"></a>t<a name="b"></a>h<a name="b"></a>e<a name="b"></a> <a name="b"></a>s<a name="b"></a>h<a name="b"></a>e<a name="b"></a>l<a name="b"></a>l<a name="b"></a> <a name="b"></a>I<a name="b"></a> <a name="b"></a>h<a name="b"></a>a<a name="b"></a>d<a name="b"></a> <a name="b"></a>n<a name="b"></a>o<a name="b"></a> <a name="b"></a>s<a name="b"></a>u<a name="b"></a>c<a name="b"></a>h<a name="b"></a> <a name="b"></a>a<a name="b"></a> <a name="b"></a>p<a name="b"></a>r<a name="b"></a>o<a name="b"></a>b<a name="b"></a>l<a name="b"></a>e<a name="b"></a>m<a name="b"></a>. </p>
