目前，我正在使用以下包含 sed 函数的 bash 脚本将数据的每个部分从一个 SCN 提取到整体之间的无字符行：

sed -n '/^SCN/,/^\s*$/p' LOG.TXT > Junction-Links.txt

这会产生以下输出：

我的问题是，是否可以将每个匹配模式保存到单独的文件中（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

使用 SCN DD1251.txt 仅包含以下内容：

在每个 Unix 机器上的任何 shell 中使用任何 awk：

$ awk '/^SCN/{close(out); out=$1" "$2".txt"} {print > out}' file

您可以使用 csplit：

csplit -z -f 'SCN DD' Junction-Links.txt '/^\s*$/' '{*}'

虽然这会使文件命名为“SCN DD00”、“SCN DD01”、“SCN DD02”等。如果您有超过 100 个文件，您可以-n 3在输出文件中添加使用三位填充。
