You can also do a find filename -size 0. If you return the filename, the
file has zero blocks.

I am looking to resolve an issue we have with a particular script.
using a unix script, I need to determine if a file exists and if the size of
the
file is zero bytes. using ftp, we put a file a file on a server then we use
get
to retreive the same file back. we do this to ensure that the file has been
sent
successfully. once the file is gotten back, using get, we compare the
original
file to the get file. we then use if to see if the file was successfully
send
and received back. if the file is not gotten back, we email the necessary
people of the error. if the files are different sizes, we email the
necessary
people that the file sizes do not match and that the ftp process needs to be
done again. all of the above steps work fine.
the issue we face is when we ftp a zero byte file and receive the same file
back
the if statement we're using sees the zero byte file as none existant and
therefore an email is sent saying that the ftp process failed when in fact
it
didn't. it just sent and received a zero byte file. a zero byte file is
not a
failed process.
finally...the question...
can a unix scripting guru assist me in the code that checks if a file is a
zero
byte file?
thanks in advance...Roy
below is the current portion of the script that checks for errors:
put file1 'file1'
get 'file1' check_file
bye
!EOF
# First if statement will check to see if the check file exists
if test ! -s "check_file"
then
# if the file does not exist, send the failed message and exit the program
echo Failed to pull a check file back from the FTP
echodo /usr/ucb/mail -s ftp_of_file1.FAILED `cat $EMAIL/fail.list` <
$EMAIL/fail.msg
