Thanks
Regards,

Code:

awk -F"|" ' NR == FNR { arr[$1]=1; next } !arr[$1] { print "Errorr" ;exit } END { print "Success" } ' filea fileb

Thank you very much anbu23 for your reply but my requirement is something different.
its like

FILE A

223|xls file pattern|ABCD|UUU
245|yyy file mmm|TRHJ|ZZZ

FILE B

disa|yyy|555223
asdf|uuu|627245

now look the 1st field of FILE A is matching with the last 3 number of 3rd field of FILE B...
this is the thing i want to do...

223 == 555223
245 == 627245
i want to match like this...

Thanks
Regards,
Pankaj

Code:

awk -F"|" ' NR == FNR { arr[$1]=$1; next }; $3 !~ arr[$1]"$" { print;exit } END { print "Success" } ' filea fileb

dear anbu23,
thanks a lot...
but can you please explain me your code?

Thankx,
Regards,

Above code doesn't work. Try this

Code:

awk -F"|" ' NR == FNR { arr[$1]=1; next }; 
	    !arr[substr($3, length($3)-2)] { print "Error" ;exit } 
	    END { print "Success" } 
' filea fileb

NR == FNR { arr[$1]=1; next } Keep first field as index and assign one to it. This block is executed till the end of first file.

!arr[substr($3, length($3)-2)] { print "Error" ;exit } Get the last three digit of third field and check whether it is an index in array arr. If not exit the processing.
