How can I check, if on remote server directory is empty or have files?
I have a script, which is supposed to run 1 day of the month, connect to remote server certain directory, find files, tar the, and copy

Code:
  
 find . -ctime -1 | tar -cvf transfer_dmz_start_monthly.tar *${Today}*.*;
 if [ $? != 0 ]
then
        echo "Cannot create a tar file, the terminated abnormaly"
        exit 1
fi
gzip transfer_dmz_start_monthly.tar
  
 /usr/bin/scp ${DESTSERVNAME}:${MONTH_DEST_DIR}/${TARGZFILE} ${LOCL_FILES_DIR}/cool_${Today}/monthly

Now problem was changed
I have to check if directory has files for Today's day. If not - exit, if yes, then logic above.

Is below code will work?

Code:
 if [ `ls | wc -l` = 0 ]
then
   exit
 else

find . -ctime -1 | tar -cvf transfer_dmz_start_monthly.tar *${Today}*.*;

 fi

Or you can find something better.
I am on AIX and have no bash
BTW, it will always have archived files , which I don't need. I.e. probably
Code:
 ls ${Today}

Thanks for contribution

bf_tar

BF_TAR(1)						    Bogofilter Reference Manual 						 BF_TAR(1)

NAME

       bf_tar - shell script to write a tar file of a bogofilter directory to stdout

SYNOPSIS

       bf_tar [-r] [-R] bogofilter_directory

DESCRIPTION

       bf_tar bundles a bogofilter working directory in tar format and copies it to standard output (your console, or where you redirect it, see
       EXAMPLES below).

OPTIONS

       The -r option causes bf_tar to remove inactive log files after the archive has been written successfully. The default is to leave log
       files.

       The -R option causes bf_tar to remove inactive log files before the archive is written. This may reduce chances that the resulting archive
       is recoverable should it become damaged. The archive may be smaller though. The default is to leave log files.

EXIT STATUS

       The script exits with status code 0 if everything went well, and nonzero if it encountered trouble.

EXAMPLES

       o   bf_tar ~/.bogofilter > outfile.tar

	   Writes a standard .tar file containing the essential files from ~/.bogofilter to outfile.tar.

       o   bf_tar ~/.bogofilter | gzip -9 -c > outfile.tar.gz

	   Writes a gzipped .tar.gz file containing the essential files from ~/.bogofilter to outfile.tar.gz.

       o   bf_tar `pwd`/mydirectory > outfile.tar

	   Prepend $(pwd)/ or `pwd`/ if you want to specify an absolute path instead of a relative path.

NOTES

       This script is meant for use with Berkeley DB based bogofilter versions.

       This script requires a SUSv2 compliant pax utility.

       This script expects a SUSv2 compliant shell. Solaris systems should have the SUNWxcu4 package installed (when bogofilter is configured) so
       that /usr/xpg4/bin/sh can be used.
