Question

我的脚本格式如下。

在我的示例中，我需要搜索“ Probable Cause:Unspecified”，一旦发现，则需要用下面的第四行替换行。

实际输出为：

Serial : blah blah blah
A-TYPE: blah blah blah
O-type: blah blah blah
instance: blah blah blah
fault: blah blah blah
sev: blah blah blah
Probable Cause: Unspecified reason
ack: blah blah blah
time: blah blah blah
Specific Event MOC: blah blah blah
cause: blah blah blah
Specific Problem: blah blah blah

，然后将找到的字符串“可能的原因：未指明的原因” Probable Cause替换为Specific Event MOC

需要最终输出：

Serial : blah blah blah
A-TYPE: blah blah blah
O-type: blah blah blah
instance: blah blah blah
fault: blah blah blah
sev: blah blah blah
Specific Event MOC: Unspecified reason
ack: blah blah blah
time: blah blah blah
Probable Cause: blah blah blah
cause: blah blah blah
Specific Problem: blah blah blah

请帮助

Answer 1

这是2次通过awk解决方案：

awk 'BEGIN{FS=OFS=":"}
FNR == NR {
   r[FNR]=$1
   next
}
/^Probable Cause:/ {
   $1 = r[FNR+3]
   n=FNR
}
FNR == n+3 && /^Specific Event / {
   $1 = r[FNR-3]
} 1' file file

Serial : blah blah blah
A-TYPE: blah blah blah
O-type: blah blah blah
instance: blah blah blah
fault: blah blah blah
sev: blah blah blah
Specific Event MOC: Unspecified reason
ack: blah blah blah
time: blah blah blah
Probable Cause: blah blah blah
cause: blah blah blah
Specific Problem: blah blah blah

说明：

BEGIN块将输入和输出字段分隔符设置为:
FNR == NR：第一次处理文件时
r[FNR]=$1：按键存储第一列作为记录编号
next：移至下一条记录
现在awk将第二次处理文件
/^Probable Cause:/：当我们在记录中找到此文本时
$1 = r[FNR+3]：将第一列设置为当前记录前面的第三条记录的第一列
n=FNR：将当前记录存储在变量n
FNR == n+3 && /^Specific Event /：当前记录为n+3时，我们以Specific Event开头的行
$1 = r[FNR-3]：将第1列设置为当前当前第3条记录的第1列

您在'd'中的数据，由gnu sed;

Config.set('graphics', 'multisamples', '0')

    def fill(self, dt):
        for i in range(30):

            self._rows["row"+str(i)] = weakref.ref(row)

    def store(self):
        #loop that will access each textinput and print its content
        print("textinput content by id or coordinates x, y")

class ShipmentsScreen(Screen):
    pass

sm = Builder.load_string(kv)

class TestApp(App):
    def build(self):
        return sm

if __name__ == '__main__':
    TestApp().run()

在一行中匹配后，用第N行中存在的字符串替换
