Hi,

here is the piece of code where i am getting error:

Code:

for i in DCP KIVR CCCD
do
        ${i}_A=`grep "2014-07-14 06" $DATA_DIR/${i}_hourly_paya.txt|awk -F '|' '{printf "%-10d\n",$2}'`



	if [[ ! -n "${${i}_A}" ]]
	then
        echo 2014-07-14 06 0 >> $DATA_DIR/${i}_hourly_paya_TMP.txt
        else
        echo 2014-07-14 06 ${${i}_A} >> $DATA_DIR/${i}_hourly_paya_TMP.txt
        fi
done

output:

$ ./san_tst.sh
./san_tst.sh: line 4: syntax error at line 12: `!' unexpected

could someone please help?

Hi,

why are you trying to use such a convoluted identifier for your local variable. Can you not do something like:

Code:

for i in DCP KIVR CCCD
do
        a=`grep "2014-07-14 06" $DATA_DIR/${i}_hourly_paya.txt|awk -F '|' '{printf "%-10d\n",$2}'`



	if [[ ! -n "$a" ]]
	then
        echo 2014-07-14 06 0 >> $DATA_DIR/${i}_hourly_paya_TMP.txt
        else
        echo 2014-07-14 06 $a >> $DATA_DIR/${i}_hourly_paya_TMP.txt
        fi
done

There may be other issues but that's what jumped out first.
