假如有个perl脚本，名字是mail.pl<br /><br />#&#33;usr/bin/perl -w<br /><br />..<br />sendattachmail;<br />..<br /><br />sub sendattachmail {<br />  open(SENDMAIL, &quot;|$sendmail&quot;);   <br />  print SENDMAIL $reply_to;<br />  print SENDMAIL $subject;<br />  print SENDMAIL $to;<br />  print SENDMAIL &quot;Content-type: text/plain\n\n&quot;;<br />  print SENDMAIL $content;<br />  close(SENDMAIL);<br />}<br /><br /><br />另外一个perl脚本，假如叫test.pl，它调用mail.pl<br /><br />mail.pl;<br /><br />我的问题是，怎么写代码，才能在test.pl中判断sendmail是否成功？<br />超级感谢，帮帮忙！<br />
