Delete a file if 0 bytes

[beaster]

I need to add to my script, the function to delete a file if it is in fact a file size of zero. The file name is alarm_sms.txt

Can anyone help out?

Thanks,
Beaster

Use this test (negated) :-
-s filename

True if filename exists and has a size greater than zero.

Eg:
# Check file exists ...
if [ -f file ]; then
# Check it's size is not greater than 0 ...
if [ ! -s file ]; then
rm file
fi
fi

I used this in my script, before as response was listed here: What do you think?

find /home/beaster/alarm_program/alarm_sms -size 0 -exec rm {} \;

It works, but it's a bit like using a sledgehammer to crack a nut. You can achive the same by saying ...

[ -s /home/beaster/alarm_program/alarm_sms ] || rm /home/beaster/alarm_program/alarm_sms

Assuming the file alarm_sms.txt is in the directory /home/beaster/alarm_program, then I'd try :-

find /home/beaster/alarm_program -name "alarm_sms.txt" -size 0 -exec rm {} \;
