Parse file contents in perl...
Hi,

I have the file like this:

Code:
#Contents of file 1 are:

Dec 10 12:33:44 User1 Interface: Probe

Dec 10 12:33:47 uSER1 SOME DATA

Dec 10 12:33:47 user1 Interface: MSGETYPE

Dec 10 12:34:48 user1 ID: 10.

Dec 10 12:33:55 user1 Interface: MSGTYPE

Dec 10 12:33:55 user1 Id: 9

Dec 10 13:09:44 user1 Method: Push down

Dec 10 13:16:15 User1 Idlist: 12:10:102:100

I should parse this file and retrieve only MSGETYPE. The output is as shown below.

Code:
Dec 10 12:33:55 user1 Interface: MSGTYPE

Dec 10 12:33:55 user1 Id: 9

Dec 10 13:09:44 user1 Method: Push down

Dec 10 13:16:15 User1 Idlist: 12:10:102:100

The file will contain many MSGTYPE but it should parse only the above output lines.

How can i get the above output?

Regards
