help parsing txt with awk
Hi all

I would need some help to introduce 'break' lines into the following
data by using awk:

original data:
Code:
RECORD 1000 aaa xxxxxx
RECORD 1001 aaa xxxxxx
RECORD 1002 bbb xxxxxx
RECORD 1003 bbb xxxxxx
RECORD 1004 bbb xxxxxx
RECORD 1005 ccc xxxxxx
RECORD 1006 ccc xxxxxx
RECORD 1007 ddd xxxxxx
RECORD 1008 ddd xxxxxx
RECORD 1009 ddd xxxxxx
RECORD 1010 ddd xxxxxx
RECORD 1011 eee xxxxxx
RECORD 1012 eee xxxxxx
RECORD 1013 eee xxxxxx
RECORD 1014 eee xxxxxx

desired output:
Code:
RECORD 1000 aaa xxxxxx
RECORD 1001 aaa xxxxxx
RECORD 1002 bbb xxxxxx
RECORD 1003 bbb xxxxxx
RECORD 1004 bbb xxxxxx
RECORD 1005 ccc xxxxxx
RECORD 1006 ccc xxxxxx
break
RECORD 1007 ddd xxxxxx
RECORD 1008 ddd xxxxxx
RECORD 1009 ddd xxxxxx
RECORD 1010 ddd xxxxxx
break
RECORD 1011 eee xxxxxx
break
RECORD 1012 eee xxxxxx
break
RECORD 1013 eee xxxxxx
break
RECORD 1014 eee xxxxxx
break

The point is that I'm not able to process it properly
with awk, so I would need some help...

Code:
awk '{ if( $3 ~ /ddd/ )                                     
       { while ( $3 == "ddd" )                               
         { getline; print $0 }                             
           print "break"
         }                             
       else if( $3 ~ /eee/ )
         { print $0 }
       else { print $0 }
     }' file.dat > new_file.dat

Thanks in advance.

LEARN ABOUT POSIX

kpasswd

kpasswd(1)							   User Commands							kpasswd(1)

NAME

       kpasswd - change a user's Kerberos password

SYNOPSIS

       /usr/bin/kpasswd [principal]

DESCRIPTION

       The  kpasswd command is used to change a Kerberos principal's password. kpasswd prompts for the current Kerberos password, which is used to
       obtain a changepw ticket from the KDC for the user's Kerberos realm. If kpasswd successfully obtains  the  changepw  ticket,  the  user	is
       prompted twice for the new password, and the password is changed.

       If the principal is governed by a policy that specifies the length and/or number of character classes required in the new password, the new
       password must conform to the policy. (The five character classes are lower case, upper case, numbers, punctuation, and  all  other  charac-
       ters.)

OPERANDS

       The following operand is supported:

       principal

	   Change  the	password  for the Kerberos principal principal. Otherwise, the principal is derived from the identity of the user invoking
	   the kpasswd command.

FILES

       /tmp/ovsec_adm.xxxxxx

	   Temporary credentials cache for the lifetime of the password changing operation. (xxxxxx is a random string.)

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWkrbu			   |
       +-----------------------------+-----------------------------+
       |CSI			     |Enabled			   |
       +-----------------------------+-----------------------------+

SEE ALSO

       SEAM(5)

BUGS

       If kpasswd is suspended, the changepw tickets may not be destroyed.
