[Whitehorse_1]

admins,

how can I find files of size "zero" bytes using "if".,

if [ -? file1 ]; then
echo "This is a ZERO byte file"; fi

Hey

check this: man test
-s file True if file exists and has a size greater than
zero.

Hi,,

I just require the opposite of wat you said, files with "ZERO size". "-s" finds non-zero files.

You reverse it with:
if [ ! -s file1 ]; then

Watch out for the "file doesn't exist gottcha when reversing the condition

! -s will PASS if

file *doesn't exist or file exist and is 0 bytes

Ok:
if [ -f file1 -a ! -s file1 ]; then
