In the following code, Im trying to imbed many statements in a single awk statement. But it gives an error on that,

for i in `less usage_types_dwh.txt`
do
cd /u01/app/evident/analysis_lab/usg_type
grep $i svc_type.txt | head -1 | awk 'BEGIN {FS=","} {print $1 "==" $2  ":" $3 ":" $4;
yesterday=$4;
day_before_yesterday=$3;
diff=day_before_yesterday-yesterday;
print "difference:" diff;
divide_by_2=day_before_yesterday/2;
print "Divide:" divide_by_2;
if ( divide_by_2 > 100 )
{
if ( divide_by_2 < diff )
{
print "****PERCENTAGE DECREASE****";
usg_type=$1;
divide_by_yes=diff/day_before_yesterday;
perc=divide_by_yes*100;
perc=perc*-1;
print "$usg_type | $perc %| $yesterday" >> /u01/app/evident/analysis_lab/ali/my_scripts/decrease_50_usagetypes.txt;
}
}
}'
cd /u01/app/evident/analysis_lab/ali/my_scripts
done

What am I doing wrong?

Hi

As a start, have a look at this line:

print "$usg_type | $perc %| $yesterday" >> /u01/app/evident/analysis_lab/ali/my_scripts/decrease_50_usagetypes.txt;

Should be more like:

print usg_type "|" perc "%|" yesterday >> "/u01/app/evident/analysis_lab/ali/my_scripts/decrease_50_usagetypes.txt"

Please post the error.
