The shell problem of the user's work:

Problem Description:

You need to intercept the certificate encoding information for the following command output:

#openssls_client-showcerts-connect192.168.0.111:443|sed-ne '/-begincertificate-/,/-endcertificate-/ P ' (The following is the certificate's output information, expected: to save the first-----begincertificate-----to-----endcertificate-----The region between the encoding to a file, the second egincertificate-----to-----endcer Tificate interval to save another file, at the same time do not use the method of fetching rows ...) What the command displays is Oldboy.log.

The recent weekly at least 4 days of class, time is very tight, here the old boy teacher only to a simple implementation, in fact, a lot of ways, sorry partners.

Simple answer:

[root@oldboytraining~]# cat oldboy.log----begincertificate-----
