Hi, thanks for helping me, i try to explain it the best i can,

AWK FILE : match_files2_o.awk

BEGIN { printf "%-5s|%-10s|%-9s|%-9s|%-9s|%-70s|%-9s|%-s\n","Count", "VT", "Date", "Time","From","Alert Message","Instance",""}
NR == FNR {
x[$1,$7]
y[FNR] = $2
next
}
!(($1,$7) in x) {
if (y[FNR]) {
$2 = y[FNR]
}
{ printf "%-5s|%-10s|%-9s|%-9s|%-9s|%-70s|%-9s|%-s\n", $1, $2, $3, $4, $6, $7, $8, ""}
}

FILE 2: managed_event_log.170108

##My Comments: in OUTPUT line with $7="kaz/switch/bin/ifstart for KAZUAT1 TOO MANY PROCESSES" exist but $2is null [ should be 13432013 - $2 from FILE 2 ]
## line where $7="isr/switch/bin/ifstart for ISRUAT3 TOO MANY PROCESSES 102802" have $2=13432030 instead of null [ becouse this line is not present in FILE 2]

##I see that for those 2 lines $1 is same and $7 is similar [ maybe this is the reason ]

First, the output I get is different than yours
(I suppose that there are some characters that disappear
with the copy/paste):

Code:
$ cat match_files2_o.awk 
BEGIN { printf "%-5s|%-10s|%-9s|%-9s|%-9s|%-70s|%-9s|%-s\n","Count", "VT", "Date", "Time","From","Alert Message","Instance",""}
NR == FNR {
x[$1,$7]
y[FNR] = $2
next
}
!(($1,$7) in x) {
if (y[FNR]) {
$2 = y[FNR]
}
{ printf "%-5s|%-10s|%-9s|%-9s|%-9s|%-70s|%-9s|%-s\n", $1, $2, $3, $4, $6, $7, $8, ""}
}

I think that you _don't_ want to set $2 based on the record number.
I feel like that the join key is only $7, am I missing something?

Code:
$ cat match_files2_o.awk 
BEGIN { 
  printf "%-5s|%-10s|%-9s|%-9s|%-9s|%-70s|%-9s|%-s\n",
  "Count", "VT", "Date", "Time","From","Alert Message","Instance",""
}
NR == FNR {
  x[$1,$7]
  y[$7] = $2
  next
}
($1,$7) in x {
 next 
}
$7 in y {
    $2 = y[$7]
}
{ printf "%-5s|%-10s|%-9s|%-9s|%-9s|%-70s|%-9s|%-s\n", 
    $1, $2, $3, $4, $6, $7, $8, "" }

This could be rewritten as:

  "Count", "VT", "Date", "Time","From","Alert Message","Instance",""
}
NR == FNR {
  x[$1,$7]
  y[$7] = $2
  next
}
!(($1,$7) in x) {
  if ($7 in y)
    $2 = y[$7]
  printf "%-5s|%-10s|%-9s|%-9s|%-9s|%-70s|%-9s|%-s\n", 
    $1, $2, $3, $4, $6, $7, $8, "" }

Thanks again Radoulov,
Last awk program works perfecly fine, this is what i need,
can you tell me how to substitute $2 and $3 from file2 to file1, so then VT and STAT will be display from file2 rest of the code will have same logic.

$ cat managed_event_log.170108
12~13432013~OPEN~ 17-01-08~10:02:32~2~KAZUAT1~kaz/switch/bin/ifstart for KAZUAT1 TOO MANY PROCESSES 001459~emeflxci~FLEX_daemons~SWITCH:KAZ:T01~CRITICAL~~100
12~13432030~CLOSE~ 17-01-08~10:02:32~1~KAZUAT1~ifreader_KZ for KAZUAT1 NOT EXIST 001459~emeflxci~FLEX_daemons~SWITCH:KAZ:T01~CRITICAL~~100

$ cat all_event_log.170108
14~~~ 17-01-08~10:02:32~2~KAZUAT1~kaz/switch/bin/ifstart for KAZUAT1 TOO MANY PROCESSES 001459~emeflxci~FLEX_daemons~SWITCH:KAZ:T01~CRITICAL~~100
12~~~ 17-01-08~10:02:32~1~KAZUAT1~ifpoll_KZ for KAZUAT1 NOT EXIST 001459~emeflxci~FLEX_daemons~SWITCH:KAZ:T01~CRITICAL~~100

OUTPUT:
Count|VT |Stat| Date |Time |From |Alert Message |Instance |
14 |13432013 |OPEN| 17-01-08|10:02:32 |KAZUAT1 |kaz/switch/bin/ifstart for KAZUAT1 TOO MANY PROCESSES 001459 |emeflxci |
12 | |NONE| 17-01-08|10:02:32 |KAZUAT1 |ifpoll_KZ for KAZUAT1 NOT EXIST 001459 |emeflxci |

Also please explain how this works:
if ($7 in y) # if found $7 in array y then replace $2 by y[$7] ? but why before y[$7] = $2 ? i'm confuse Smilie
$2 = y[$7]
# 18  
Old 01-18-2008
But we have another problem here: the primary key ($1,$7)
is not unique in managed_event_log.170108:
12,KAZUAT1 for both records. We have to add another element
(field?) to the key, it has to be unique. Which part of $8 can be considered ("TOO MANY PROCESSES", "NOT EXIST" or something
else)?
# 19  
Old 01-18-2008
Yes i know that now our primary key will be $8
so now awk will looks like that:
BEGIN {
printf "%-3s|%-10s|%-4s|%-9s|%-9s|%-9s|%-70s|%-9s|%-s\n", "Cnt", "VT", "STAT", "Date", "Time","From","Alert Message","Instance",""
}
NR == FNR {
x[$1,$8]
y[$8] = $2
z[$8] = $3
next
}
!(($1,$8) in x) {
if ($8 in y)
$2 = y[$8]
$3 = z[$8]
printf "%-3s|%-10s|%-4s|%-9s|%-9s|%-9s|%-70s|%-9s|%-s\n", $1, $2, $3, $4, $5, $7, $8, $9, "" }

It's working!!!! Smilie
Thanks

Hi,

I have stumbled upon many awk scripts which does merging of information from 2 files. I tried to use some of them for my task, but nothing really helped me in accomplishing my desired output Smilie
Here is what I am try to do ....
I have 2 files - main.txt and alternate.txt. Contents of main.txt is as given below -
A123|msg a 1|date a 1|other info a 1
B234|msg b 1|date b 1|other info b 1
C123|msg c 1|date c 1|other info c 1
D456|msg d 1|date d 1|other info d 1
.....
and so on

Contents of alternate.txt is as given below -
B234|1.1|msg b 2|remarks 1
B234|1.2|msg b 3|remarks 2
D456|1.1|msg d 2|remarks 1
D456|1.2|msg d 3|remarks 2
D456|1.3|msg d 4|remarks 3
D456|1.4|msg d 5|remarks 4
..... and so on.

Common key between the above files is column 1 (A123, B234, etc.). I want to consolidate the information available in the 2 files such that the result is as given below -

A123|msg a 1|date a 1|other info a 1
B234|msg b 1|date b 1|other info b 1
B234|1.1|msg b 2|remarks 1
B234|1.2|msg b 3|remarks 2
C123|msg c 1|date c 1|other info c 1
D456|msg d 1|date d 1|other info d 1
D456|1.1|msg d 2|remarks 1
D456|1.2|msg d 3|remarks 2
D456|1.3|msg d 4|remarks 3
D456|1.4|msg d 5|remarks 4

Basically, for every record which is present in main file, if there are any entries in alternate file, print those records subsequently in the result file. Any help with this is highly appreciated.

Thanks and Regards,
Vidya

You may try something like this (use nawk or /usr/xpg4/bin/awk on Solaris):

Code:
awk -F\| 'NR == FNR {_[$1] = _[$1] ? _[$1] RS $0 : $0; next }
($1 in _ && $0 = $0 RS _[$1]) || 1' alternate.txt main.txt
