有没有办法将sed脚本的每个匹配结果分别提取到一个文件中？
Is there a way to extract each matching result of a sed script to a file each?
我的文件结构如下所示，只是包含更多部分：

目前，我正在使用以下包含 sed 函数的 bash 脚本将每个数据段从一个 SCN 提取到整个之间没有字符的行：
sed -n '/^SCN/,/^\s*$/p' LOG.TXT > Junction-Links.txt
这会产生以下输出：
SCN DD1251 At Glasgow Road - Kilbowie Road

我的问题是，是否可以将每个匹配模式保存到一个单独的文件（即 SCN DD1251 的文件、SCN DD1271 的文件等）而不是将它们全部保存到一个组合文件中？
理想情况下输出应该是这样的：
- SCN DD1251.txt
- SCN DD1271.txt
- SCN DD1301.txt
- SCN DD1351.txt
SCN DD1251.txt 仅包含以下内容：

你可以使用 csplit:
csplit -z -f 'SCN DD' Junction-Links.txt '/^\s*$/' '{*}'
尽管这会生成名为 'SCN DD00'、'SCN DD01'、'SCN DD02' 等的文件。如果
你有超过 100 个文件，你可以添加 -n 3 以使用三位数填充
在输出文件中。
在每个 Unix 机器上的任何 shell 中使用任何 awk：
$ awk '/^SCN/{close(out); out=" "".txt"} {print > out}' file
$ head SCN*
==> SCN DD1251.txt <==
