Code:
$ awk 'FNR == NR{v[$1]=$2; next} FNR==1 {n=$2=v[$3]+1} FNR==2 || $3=="All_Total" {$2=n}1' FS=: file1 FS=\| OFS=\| file2

Code:
Sale|11|London|3|28022018
Approval|11
Agent1|12|abc|abc|
Agent2|12|abc|abc|
Agent3|12|abc|abc|
Final|11|All_Total

Hello Aia,RudiC,

Yes this code works find to update file2. Hope can I update the file1 with the increase count ?

E.g. Since we have updated file2 to
Code:
Sale|11|London|3|28022018
 Approval|11
 Agent1|12|abc|abc|
 Agent2|12|abc|abc|
 Agent3|12|abc|abc|
 Final|11|All_Total

File1 should be increment to 11 as well.

e.g.
Code:
London:11

Can somebody suggest quick way?

Try
Code:
awk '
NR == FNR       {TR[$1] = $2
                 SQ[NR] = $1
                 next
                }
FNR == 1        {CITY = $3
                 for (n=split(PLINES, TMP); n; n--) LINES[TMP[n]]
                 TR[CITY]++
                 while (SQ[++n]) print SQ[n] ":" TR[SQ[n]] > "TEMPFILE"
                }

$1 == "Final" ||
FNR in LINES    {$2 = TR[CITY]
                }
1
' FS=: file1 FS=\| OFS=\| PLINES="1|2" file2

and then rename TEMPFILE to file1.

Can the above code from RudiC be modified to cater to below file2 as well?

file1:
Code:
LONDON:5500
NEWYORK:4500
AMSTERDAM:3500

file2:
Code:
"MKTG",LONDON,"EXPENSE",20160606,20160606,5000
"EMPLOYEE1",XXXX,"XXX","XXX"," ,"D","",1000
"EMPLOYEE2",XXXX,"XXX","XXX"," ,"D","",1000
"EMPLOYEE3",XXXX,"XXX","XXX"," ,"D","",1000
"EMPLOYEE4",XXXX,"XXX","XXX"," ,"D","",1000
"EMPLOYEE5",XXXX,"XXX","XXX"," ,"D","",1000
"FINAL",4,TOTAL_EXPENSE,YYYYYYYYY

I want to do the same thing.
1. Read "LONDON" from file 2 i.e. second field. The field separator is comman (,) instead of pipe.
2.Read file1 to find the count for LONDON i.e. 5500.
3. Update 6th field in the file2 i.e. 5000 to 5501
4. Update the file1 with 5501 (i.e. increament the counter by one)

Contrary to pervious file which has pipe delimiter and also i needed to update three rows.. here i need to update only single row i.e. the first row in the file.

Thanks

You've changed your requirements several times and not have shown us that you have made any attempt at all to modify code that you've been given to meet your newly added requirements.

Why don't you try making some of these changes on your own, show us what you have tried, and let us know if you get stuck getting the output you want.

We want to help you learn how to do things like this on your own. If you're given code that you don't understand, ask the person who gave it to you to explain how it works. We are not here to act as your unpaid programming staff.

Not at all Don. Here is the code... i am trying to execute. The requirement is same just different fields and row numbers.

Getting the city : LONDON

Code:
var1=`awk 'FNR=NR {print $2}' FS=, file2 | head -1`

Getting: the counter
Code:
var2=`grep $var1 file1 | awk '{print $2}' FS=:`

increment counter y 1
Code:
var3 = $((var2+1))

So now.. i have the inceased counter, and also the city for which I need to replace the counter.

I can replace the increased counter file 1 by using below:

Code:
awk -F\| '{gsub($var1':'$var2,$var1':'$var3,$1);}1' OFS=\: file1



But how can I replace the value in file2? Now give that RudiC solution is more efficient and neat.... i chose to use that. But If I know how to replace in file1 (field 6).. i can use mine too as I have got most of the value in variables now.

Wouldn't it have been nice to see your attempt with awk?

Howsoever, try
Code:
awk '
NR == FNR       {TR[$1] = $2
                 SQ[NR] = $1
                 next
                }
FNR == 1        {CITY = $2
                 $6 = ++TR[CITY]
                 while (SQ[++n]) print SQ[n] ":" TR[SQ[n]] > "TEMPFILE"
                }
1
' FS=: file1 FS=, OFS=, file2
"MKTG",LONDON,"EXPENSE",20160606,20160606,5501
"EMPLOYEE1",XXXX,"XXX","XXX"," ,"D","",1000
"EMPLOYEE2",XXXX,"XXX","XXX"," ,"D","",1000
"EMPLOYEE3",XXXX,"XXX","XXX"," ,"D","",1000
"EMPLOYEE4",XXXX,"XXX","XXX"," ,"D","",1000
"EMPLOYEE5",XXXX,"XXX","XXX"," ,"D","",1000
"FINAL",4,TOTAL_EXPENSE,YYYYYYYYY
cat TEMPFILE 
LONDON:5501
NEWYORK:4500
AMSTERDAM:3500
