SED问题
我需要打印11月份包含11或12月份包含12行的所有行。
我的两个问题是:
到目前为止我所拥有的:
sed -n -e '/11/,/12/p' datebook
档案datebook

如何告诉搜索在第4列中查看哪些日期?
这表明您应该使用awk
因为sed
没有字段的概念。 awk
解决方案将是
awk -v FS=":" '$4 ~ /^1[12]\/.*/{print}' datebook
<强>输出强>

解密解决方案
FS=":"
将字段/列分隔符设置为冒号。$4
代表输入文件中的第四列,即mm/dd/yy
~
中的$4 ~ /^1[12]\/.*/
表示我们正在进行正则表达式匹配
^
表示字符串的开头[12]
可以匹配一两个。/
分隔,因此您需要转义任何文字/
,如\/

您似乎想要选择行第三个冒号后的第一个字符为11/
或12/
的行(因为数据格式似乎是Y2K之前的US格式日期为mm/dd/yy
符号)。所以你写道:
$ sed -n '/^\([^:]*:\)\{3\}1[12]\//p' datebook

$
^
在一行开头匹配; \([^:]*]:\)
部分查找一系列零个或多个非冒号后跟冒号; \{3\}
需要其中3个;之后1[12]\/
要求11/
或12/
; p
打印。
我观察到最初的陈述说“11月份包含11或12月份包含12”,但您的第一个编号问题是“价值11和12”。这些是矛盾的;给定的日期字段只能以一个或开始,而不是两个。我认为'或'就是你想要的。
