problem in scripting

Question

when I am executing this on the command line:

awk 'BEGIN{OFS=FS=","}$3~/^353/{print}' axeM10_20110510100219_59.DAT_353 >log

it executes vey nicely without taking much time and instantly gives me the output file.

but when I am including this in a shell script :

#!/usr/bin/ksh

for i in *.DAT_353
do
awk 'BEGIN{OFS=FS=","}$3~/^353/{print}'  ${i} > ${i}_changed >/dev/null
done

exit

the script is generating a 0 byte files. may I know what is the problem here?

Answer 1

Remove >/dev/null because that is where your stdout is being redirected to.
