在fi中的特定行后添加空行

Question

有人能帮我吗？我想在带有“------BEGIN RSA PRIVATE KEY-----”的行之后添加空行（enter），在带有“------END RSA PRIVATE KEY-----”的行之前添加空行（enter）

文件中的所有数据都不是静态的，所以我认为可以使用sed或python根据行数（行数总是相同的）来完成。。。你知道吗

这是我的文件（使用vi和“set nu”命令打开）：

 38 -----END RSA PRIVATE KEY-----'

Answer 1

“\n”在python中添加新行，用于在字符串中添加新行

Answer 2

以下内容可能对您有所帮助。你知道吗

awk '/BEGIN RSA/{$0=$0 ORS} /END RSA/{$0=ORS $0}1' Input_file

如果您想将输出保存到输入文件本身，请在上面的命令中附加> temp_file && mv temp_file Input_file。你知道吗

Answer 3

多种方式，例如使用awk：

awk '/-----END RSA PRIVATE KEY-----/ { print "" }
{ print }
/-----BEGIN RSA PRIVATE KEY-----/ { print "" }' origfile.txt >result.txt

Vi也可以编写脚本来打开文件，添加两行并关闭（至少Vim可以）
