linux - 如何同步两个文件的内容

Question

我想同步两个文件的内容，File1 & File2

这两个文件的共同内容很少。

• File2 是主文件。
• File1 是普通文件。

文件2：

# cat File2

    [default]
host = XXXX

<i>[monitor:///server/dev-01/log/*.log*]</i>

index = main

disabled = false

sourcetype = serverlog

文件1：

# cat File1

    [default]
host = XXXX

<i>[monitor:///server/cat-01/log/*.log*]</i>

index = second

disabled = false

sourcetype = server-logs

必需的：

# cat File2


    [default]
host = XXXX

<i>[monitor:///server/dev-01/log/*.log*]</i>

index = main

disabled = false

sourcetype = serverlog

<i>[monitor:///server/cat-01/log/*.log*]</i>

index = second

disabled = false

sourcetype = server-logs
