help in awk script
Hi mates,

I have this code which is returning error as shown below, what am trying to do is create a sub array from each line the grep returns a line and check for valur and print the whole line.

Code:
#!/bin/sh
for i in `cat list`
do
        grep -iw $i dump| awk '{print $0"\n"}'|awk -F 'BEGIN { FS="\n" }
                                    {array1 [NR]=$1 }
                                    END {
                                         for (i=1;i<=NR;++i)
                                         N=split(investigate,core," ")
                                         for (j=1;j<=N;++j)
                                        if (core[3] == "Hello" ) { printf "%s\n",core[k] }
                                        }'
done

It throws following error :

Code:
awk: illegal reference to array investigate
 record number 2
awk: illegal reference to array investigate
 record number 4
awk: illegal reference to array investigate

Please guide as to what could be wrong ?...

Some problems with your script:
  • You're using 3 undefined variables in your awk command: investigate, k and N.
  • The call of awk (twice) and grep within a loop is not efficient, probably you can get the output with one awk command.
Can you post the input file and the desired output?

My bad
Iam sorry franklin the script should have been this :

Code:
#!/bin/sh
for i in `cat ugname`
do
        grep -iw $i logs | awk '{print $0"\n"}'|awk -F 'BEGIN { FS="\n" }
                                    {array1[NR]=$1 }
                                    END {
                                         for (i=1;i<=NR;++i)
                                         N=split(array1,core," ")
                                         for (j=1;j<=N;++j)
                                        if (core[3] == "Hello" ) { printf "%s\n",core[N] }
                                        }'
done

What iam actually trying to do is that, scripts greps certain keywords in log file and prints certain fields within the returned line .

Thnks in advance

You can't split an array and we can't give a correct answer without the input file and the desired output.

Hi
Hi Franklin/All,

So i'll try give you more info on this (though i may not be able to be exhaustive). We have a backup tool running, which does file system backup and db backup for clients grouped into 2 categories according to their locations, and it logs messages file with statements like starting/ restarting groups whenever it starts and restarts (manual intervention). Besides it also logs failure of backup for a particular client in particular group. Also a group typically consist of 1 - 30 clients generally.

Following is an example :

Code:
Dec  1 18:00:01 server root: NetWorker savegroup: (info) starting  goupx (with 23 client(s))

Dec  2 11:01:01 server root:  NetWorker savegroup: (notice) goupx completed, total 23 client(s), 0 Hostname(s) Unresolved, 0 Failed, 23 Succeeded.

Dec  2 18:00:02 server root:  NetWorker savegroup: (info) starting  groupy (with 23 client(s))

Dec  3 12:41:40 server root: NetWorker savegroup: (alert) groupy completed, total 23 client(s), 0 Hostname(s) Unresolved, 1 Failed, 22 Succeeded. (clientA Failed)

Dec  3 18:00:02 server root: NetWorker savegroup: (info) starting  groupy (with 23 client(s))

Dec  4 15:13:10 server root:  NetWorker savegroup: (notice) groupy completed, total 23 client(s), 0 Hostname(s) Unresolved, 0 Failed, 23 Succeeded.

Dec  4 18:00:02 server root:  NetWorker savegroup: (info) starting  groupE (with 23 client(s))

What we have to do is process this messages log file and tell whether clientA in groupy failed 1 time or 2 time or 0 time or n times.

Besides if a group starts and finishes with 0 failures as soon as it starts then its a skip , as backup never happened for those client in that group because of configuration set on the backup server for the client, though group may start everyday same time. **(explained further down)

So far i have this code. It greps failure groups from failures fail and grep them again on messages file for details, it analyzes them, if completed statement then check, number of failures, if not zero prints the failure clients with group name. This kind of analysis is done with the help of array, which is an array of each word in line, we get from grepping the group from messages file (stored in investigate).

Code:
for i in `cat ugname`
do
grep -iw $i messages |tail -20| awk -F 'BEGIN { FS="\n" }
                                {investigate[NR]=$1 }
                                END {
                                        for (i=NR;i>=1;--i) {
                                        k=split(investigate[i],core," ")
                                        if (core[13] == "completed," && core[20] == "0")
                                        {
                                        print core[12]"\tcompleted"
                                        break
                                        }
                                        else  {
                                                x=24
                                                while ( x < k ) {
                                                print core[x]"\t"core[12]
                                                ++x }
                                                }
                                                                }
}'

The output is stored in a file temporarily and then counted for repeated words in the output giving failure counts for repeated line.

So i need someone helping me in identifying a skip ie a group starting at dec 25 00:00:00 and ending at dec 25 00:01:00 , reporting a completed statement with 0 failures.

Thanks in advance

Just using nawk or gawk do the below:-

Code:
nawk  '/starting/{grp=$10 ; next}
($0 ~ grp) && /completed/{a[grp]=a[grp]"\t"$17" "$18" "$1 " "$2" "$3}
END{for (i in a) {print i,"--->",a[i]} }
' file.txt


Code:
o/p:-

groupy --->     1 Failed, Dec 3 12:41:40        0 Failed, Dec 4 15:13:10
goupx --->      0 Failed, Dec 2 11:01:01

Is this the expected o/p that you desire???
