Check for file size is zero or not.

Shell Programming and Scripting
1

I have following script on AIX/KSH

if [[ -s file1 ]] ; then
echo "filename exists and is > 0 bytes"
else
echo "filename does not exist or is zero length"
fi

It is not working. What is wrong here???

2

if its KSH the write
if [ not if [[
so
if [ ! -s file1 ] ; then

3

if [ -s file1 ] ; then
echo "filename exists and is > 0 bytes"
else
echo "filename does not exist or is zero length"
fi

This also does not work..

It worked, my file name had path and it was a different file,,,,
