我是awk和 的新手sed。我有以下几行，如果它与模式不匹配，我想将它向上移动。
文件：
company name
address line
city, state, zip
extra info
company name
address line
city, state, zip
extra info
company name
address line
city, state, zip
extra info
......它就这样继续下去
想使用模式匹配 'company name' 。如果该行没有“公司名称”，则向上移动该行。
期望的输出：
company name, address line, city, state, zip, extra info
company name, address line, city, state, zip, extra info
company name, address line, city, state, zip, extra info
...然后继续
谢谢你的帮助
