Manual steps
top -b -n 1 -p `ps -eaf |grep -v grep |grep radars-lnx |awk {'print $2'}` |grep `ps -eaf |grep -v grep |grep radars-lnx |awk {'print $2'} ` |awk {'print $2" "$10" "$11'}
output as below
root 1.0 412:24.56
刚刚尝试了如下所示的regexp..print（“outlines”，outlines）regnew=re.search（r'（[a-z]+）（[0-9]+\[0-9]|[0-9]。（[0-9].*），outlines）print（regnew.group（1））print（regnew.group（2））print（regnew.group（3））root 1.0415:03.49 print（regnew.group（1）+++regnew.group（2）+regnew.group（3））o/p根目录1.0 415:08.08，但预期的输出没有使用regexp作为手动命令，因此输出正确且有空格。
