Silly example, but might help.
#! perl -slw
use POSIX qw(:errno_h :sys_wait_h);
use constant {
RET_SUCCESS => 1,
RET_FAILURE => 0,
};
sub check_process_signal {
my $sig = shift;
if ( WIFEXITED($sig) ) {
print q{process normal exit};
return RET_SUCCESS;
} elsif ( WIFSIGNALED($sig) ) {
print q{process terminated because of signal};
return RET_FAILURE;
} elsif ( WIFSTOPPED($sig) ) {
print q{process is stopped};
return RET_FAILURE;
}
return RET_SUCCESS;
}
my $pid = #run your command however....
waitpid( $pid, 0 );
if ( check_process_signal( $? ) ) {
## success...
} else {
## failure ...
}
Coded on the fly sorry if there are any errors.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
