Code:
{ if(CONDITION = strcondition(COND)) print CONDITION"|"$147"|"$15"|"$16"|"$17"|"$4 }

Hi,

Before I post i store the condition in a variable as like below(in 2 steps) and after that i merged in the same awk as per above snippet, however the problem statement remains the same where iam unable to execute the if statement with dynamically formed condition.
Code:
CON=`echo ""|/usr/bin/awk -v COND=${CONDITIONS} -F"," 'function strcondition(h,  i,F,v,b,dec) {F=split(h,v,",");for(i=1;i<=F;i++) {split(v[i],b,"=");dec=(dec != "") ? dec""sprintf(" %s == \"%s\" &&",lookup(b[1]),b[2]) : sprintf("%s == \"%s\" &&",lookup(b[1]),b[2]);} sub(/[ &&\t\r\n]+$/, "", dec);return dec;} function lookup(l,  f,ar){ar[1]="$1";ar[2]="$4";ar[3]="$60";ar[4]="$17";ar[5]="$4";if (l in ar) {return ar[l];}} { print(strcondition(COND))}'`

/usr/bin/awk -v CONDITION="${CON}" 'BEGIN{FS=","}{ if (CONDITION) {print CONDITION"|"$147"|"$15"|"$16"|"$17"|"$4} }' Record_${FILEDATE}.dat

Hi rdrtx1, It works perfectly. Many thanks for your support.

Hi ,

I have simplified the solution and sharing the final solution for others.
Code:
CONDITIONS="1=CT,2=US_10,3=CT_US_10"

awk -v CONDITION="${CONDITIONS}" -F, 'BEGIN { c=split(CONDITION, cons, ","); for (i=1; i<=c; i++) { split(cons[i], cs, "="); field=lookup(cs[1]); gsub("[\"]", "", cs[2]); conditions[field]=cs[2];}}
function lookup(l,  ar){ar[1]="1";ar[2]="4";ar[3]="60";ar[4]="17";ar[5]="4";if (l in ar) {return ar[l];}}
{
n=0;
for (i in conditions) if ($(i)==conditions[i]) n++;
if (n==c) print CONDITION"|"$147"|"$15"|"$16"|"$17"|"$4;
}
' Record_${FILEDATE}.dat

Then you should consider properly formatting your code, so others can easily read it.

Thanks.

more simple?
Code:
CONDITIONS="1=CT,4=US_10,60=CT_US_10"

awk -v CONDITIONS="${CONDITIONS}" -F, '
BEGIN { c=split(CONDITIONS, cn, "[=,]"); }
{n=0;
for (i=1; i<=c; i+=2) if ($cn[i]==cn[i+1]) n+=2;
if (n==c) print $0;
}' file

Thats cool rdrtx1. However anxious to see how OR condition works as below are AND conditions.

In our example the below conditions are treated as AND conditions and file got processed.
Code:
CONDITIONS="1=CT,2=US_10,3=CT_US_10"

converted to
Code:
CONDITIONS="1=CT,4=US_10,60=CT_US_10"

Can you please throw some light on how to work with AND,OR conditions together if the condition comes dynamically from user input. Below is an example.

Code:
CONDITIONS="(1=CT or 2=US_10) and 3=CT_US_10 and 4="
