sed多行搜索例子（跨行搜索）

for i in {1..15}
do
    let num=$i;
    let c=$i+1
    if [[ $i -lt 10 ]] ;then
        v=0$i
    else
        v=$i
    fi
    if [[ $c -lt 10 ]] ;then
        cc=0$c
    else
        cc=$c
    fi

    echo v=$v
    echo cc=$cc

    cat en2 |sed  -n  '/'$v'-[A][.]/p' >> ok/$v.txt
    cat en2 |sed  -n '/'$v'-[A|B][.]/{:a;n;/'$cc'-[A|B][.]/!p;/'$cc'-[A|B][.]/!ba}' >> ok/$v.txt
    
done

 cat en2 |sed  -n '/'$v'-[A|B][.]/{:a;n;/'$cc'-[A|B][.]/!p;/'$cc'-[A|B][.]/!ba}' >> ok/$v.txt
解释一下

     

 -n 默认不打认所有

'$v'-[A|B][.]为开始标记正则 

'$cc'-[A|B][.] 为结束标记正则

/'$cc'-[A|B][.]/!p; 在两标记之间的行的处理方式，打印除结束标志所在行以外的所有行

:a;n;  :a意为自定义标签名 n;意为提交读取下一行。

!ba意为 !意为找取了结束标记 b意为跳出循环 a是前面自定义标签名:（如果找不到结束标签则继续跳到:a）
