用每个文件的L10字符7-11中的值替换多个文件中的模式

Question

大家好，

我想知道您是否可以帮助我处理UNIX命令/命令集，这些命令修改当前目录中的所有".mos“文件(其中只包含文本行)如下:我想用.mos替换每个文件的"ExternalENodeBFunction=1”条目

ID是从每个文件的第10行字符7-11读取的.我知道我可以使用sed命令来用其他字符串替换模式，或者使用awk命令，但是我不知道/理解如何用特定的字符串位置替换模式。

非常感谢你的帮助，

卡特林

PS --我添加了一个带有输入和期望输出的图片。

输入：

Answer 1

你想要的是这样的东西：

awk '
NR < 10 {
    buf[NR] = $0
}
NR == 10 {
    eNBId = $2
    for (i=1; i<NR; i++) {
        sub(/ExternalENodeBFunction=[0-9]+/,"ExternalENodeBFunction="eNBId,buf[i])
        print buf[i]
    }
    print
}
NR > 10 {
    sub(/ExternalENodeBFunction=[0-9]+/,"ExternalENodeBFunction="eNBId)
    print
}
' file

但是它显然没有经过测试，因为您没有提供任何我们可以进行测试的示例输入/输出。

Answer 2

sed ': load
# load lines (1 by 1) until Not last one
   $ !{N;b load
      }
# keep a copy into holding buffer
      h
# Extracting the number to substitute
   s/^\([[:alnum:][:blank:][:punct:]]*\n\)\{9\}.\{6\}\(....\).*/\2/
# add all the line after this (1st line is the number)
   G
: repl
# replace last occurence of External with the new reference
   s/^\(....\)\(.*\)\(ExternalENodeBFunction=\)1\([^0-9]\)/\1\2\3\1\4/
# if replacement occur, (re)try another one
   t repl
# cleanning by removing first number (4 digit + 1 new line)
   s/.....//
   ' YourFile

• 使用这个sed查找(或循环中的grep )将为您提供所有要转换的文件。
• 假设有第10行包含信息(这里的脚本不是安全的，但可能很容易)
• 需要在内存中加载文件(两次)，所以不是最好的大型文件(不知道.mos的平均文件大小，希望它不是1GB)
• 假设文件没有由外部结束以更改(如果需要可以修改)，如样例中所示
