[AWK] handeling data spread on multiple lines

Hello all,

first off great forum.

Now for my little problem.

Using RHEL 5.4 and awk. Been doing code since a few month. So just starting.

My problem is handeling data on multiple lines.

Code:

{
if ($1 != LASTKEY && h["canonicalName"] ~ /.*\/s_fr_[a-z]/)  {
        checkgecos( h["unixname"], h["gecos"] ) 
        h[unixname]=""
        h[gecos]=""
}
if ($2 == "gecos" || $2 == "unixname" || $2 == "canonicalName") {
        h[$2] = $3
}
LASTKEY = $1
}

This code handles great the following data:

toto1:unixname:toto1
toto1:uid:4567
toto1:gecos:Toto Toto
toto1:canonicalName:us.bla.bla.bla
bob2:unixname:bob2
bob2:uid:7676
....

But i can't figure out how to handle this kind of data spread on multiple lines (ex: sudo.log file)

Mar 9 17:24:28 : toto : TTY=pts/2 ; PWD=/home/toto ; USER=root
; COMMAND=/bin/cat /var/log/sudo.log

Of course to add more problem... It can be spread on more then 2 lines...

Jan 29 12:10:50 : toto : TTY=unknown ; PWD=/home/toto ; USER=root ;
COMMAND=/bin/nice find / /export /boot blablabla -mount
-type f -name catalina.jar -o -name license.bea -o -name weblogic.jar -o
-name httpd -o -name config.nice

Tried with a while and getline to get second line but that didn't seem to do the trick.

What are you guy's tricks for handleling multiple line data?

Below an example of what I mean. The first attempt does what I want; the second doesn't, because bash assumes a line break means the end of an individual "command unix". Is there some way that I can convince bash to parse out, eg, to the closing parenthesis? I'm thinking this would allow for...
