使用终端将文本拆分为常规重复文本字符串之间的文件

  • 772

我在固定时间间隔内有几段文本，我正尝试使用 shell 将其解析为单独的文件。该文件的格式如下：

<Line delimiter>
The lines of text to extract
<Line delimiter>
Other lines that are to be extracted but
also have an unpredictable length
<Line delimiter>
...
...
<Line delimiter>
and so forth

我正在尝试一个Split命令并在行之间进行 grepping，如下所示：

for line in $(grep -n 'Line Delimiter' target.txt | cut -d ':' -f 1); do split -l $line target.txt  ; done

此外，这个带有头部 | 尾部管道的装置似乎是本例中一个很有说服力的解决方案。我对此进行了更多的搜索，并进行了几次其他尝试，但我觉得这应该相对容易，但要完成这项壮举超过 1 次迭代却很困难。任何帮助都提前谢谢了。

    简单的例子希望有帮助

    $ cat input.txt
<Line delimiter>
The lines of text to extract
<Line delimiter>
Other lines that are to be extracted but
also have an unpredictable length
<Line delimiter>
these should also go...
into another file ...
<Line delimiter>
and so forth
$
$ #repeat the split as many times as the match is made
$ csplit -q input.txt '/<Line delimiter>/' '{*}'
$
$ # file xx00 is empty as the first occurence of <Line delimiter> is line 1   
$ cat xx01
<Line delimiter>
The lines of text to extract
$ cat xx02
<Line delimiter>
Other lines that are to be extracted but
also have an unpredictable length
$ cat xx03
<Line delimiter>
these should also go...
into another file ...
$ cat xx04
<Line delimiter>
and so forth
