标题: 有关系统日志的筛选的请教

--------------------------------------------------------------------------------


例如 我的日志中有类似这样的记录

**** *** **　ip1 *****
＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
**** *** **　ip1 *****
＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
**** *＊＊＊＊＊＊** **　ip1 *****
**** **＊＊＊＊＊＊＊＊＊＊**　ip1 *****

**** *** **　ip2 *****
＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
**** *** **　ip2 *****
＊＊＊＊＊＊＊＊＊
＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
**** *** **　ip2 *****

上万行的日志,每行和每行之间的日志不是规则化的，不直接符合正则表达的要求
我怎样把日志中所有相关的ＩＰ筛选出来，然后去掉重复的，并且将ＩＰ排序？？

try

1. grep -oiE '([0-9]+\.){3}[0-9]+' file | sort -u
