看来要加强汉语言的学习

哈哈 经常看见 大天使 很快的错误理解LZ的意思。

此方法无法对日期进行一个按照月与日进行递增，只能显示特定的字段，离我想要的结果还是有点距离，不过仍然谢谢这位兄弟给与的帮助！

try:

1. awk '{d=mktime(gensub("-"," ","g",$1)" 00 00 00");for(i=1;i<=30;i++){$1=strftime("%F",d+86400*i);print > "sn"sprintf("%02d",i)}}' urfile

复制代码

未测试

1. awk '$1=="2009-03-28"{sub($1,"2009-03-29");print >"sn01"}$1=="2009-03-30"{sub($1,"2009-04-01");print >"sn02"}$1=="2009-01-31"{sub($1,"2009-04-01");print >"sn03"}$1=="2009-02-30"{sub($1,"2009-04-01");print >"sn03"}$1=="2009-03-31"{sub($1,"2009-04-01");print >"sn03"}' file

你好，你提供给我这条语句已经比较符合我的需求了，可是有一个问题，就是，为啥执行该条语句后，会在我的日志文件中多加了一列，时间变成了以下格式：

还请各位多多指教！

这个不是代码加进去的吧，是你的编辑器带的行号吧。
直接 cat 的结果就是这样？

1970-03-02这个字段，本身的日志文件是不存在的！就是执行了你那台awk命令之后就出现了！

不知道你的环境，自己调试调试吧：

1. $ cat urfile
