Parsing a file with different patterns
I have a text file like this , where the same set of three lines repeat with different values.
Code:
INFO:  processing now 03/25/2015-00:06:05 03/25/2015-00:16:04
------Invoking myexe table=table1 
INFO  25-03 00:20:26,801 - Finished processing (I=0, O=57, R=57, W=57, U=0, E=0)
INFO:  processing now 03/25/2015-00:20:09 03/25/2015-00:25:04
------Invoking myexe table=table2 
INFO  25-03 00:20:26,801 - Finished processing (I=0, O=57, R=59, W=57, U=0, E=0)

0
Now my requirement is to parse this file and create an output like this.
Code:
 03/25/2015-00:06:05 03/25/2015-00:16:04  table1 W=57
 03/25/2015-00:20:09 03/25/2015-00:25:04 table2 W=57

As each line has a different pattern, I am not sure how to do this in a single shot. Please help. .

securetty

SECURETTY(5)						     Linux Programmer's Manual						      SECURETTY(5)

NAME

       securetty - file which lists terminals from which root can log in

DESCRIPTION

       The file /etc/securetty contains the names of terminals (one per line, without leading /dev/) which are considered secure for the transmis-
       sion of certain authentication tokens.

       It is used by (some versions of) login(1) to restrict the terminals on which root is allowed to login.  See login.defs(5) if  you  use  the
       shadow suite.

       On  PAM	enabled  systems,  it  is  used  for  the  same purpose by pam_securetty(8) to restrict the terminals on which empty passwords are
       accepted.

FILES

       /etc/securetty
