Bash脚本产生空文件

Question

I have created a script so I can search for 0kb files in a certain path, the output is to be redirected to a text file and then emailed. The script works except that the fie is empty either when it's emailed or when it's viewed after the script runs.

if [[ -n $(find /path/to/files/ -type f -empty -mmin +2) ]] then
> /tmp/output.txt ; mail -s "subject" -a /tmp/output.txt "email@address"
rm /tmp/ftr_output.txt
fi   

Not sure if I missed something so any help would be appreciated.

Thanks

I guess you want something like this:

# Save find results in a text file
find /path/to/files/ -type f -empty -mmin +2 > /tmp/output.txt

# Check that the text file isn't empty (meaning no results from find)
if [ -s /tmp/output.txt ]
then
    # Send the text file along with an email
    mail -s "subject" -a /tmp/output.txt "email@address"
fi
# Remove the text file
rm /tmp/output.txt
