Tar file with newly created file
Hello guys
thanks for this helpful forum.

I'm new to scripting and doing a little script that dump a sql database with some extra files from a VM of the company I'm in, and create a tar archive to be saved on our serve.

How can I have the tarball to be created with the files generated in the same script?
I keep getting: "cannot extract file, archive empty"

I've tried a wait 10 but that doesn't help.

Code:
#!/bin/bash
#
#VARIABLES
#working directory
wd=/opt/fs_db_backup/
if [ ! -d $wd ] ; then
   mkdir $wd
fi
runDate=`date +%d_%m_%y-%H%M%S`
vers=$(/home/leo/bin/leostatus | grep vers | awk '{print $5}' | sed "s,\x1B\[[0-9;]*[a-zA-Z],,g")
#DUMPING THE DATABASE
/usr/local/pgsql/bin/pg_dump -U leo -f $wd/sql
#CREATES FILE NEEDED FOR RESTORATION
touch $wd/version
touch $wd/md5
#populate and change permissions
echo -n $vers >> $wd/version
#respect the order 
cd $wd
md5sum sql >> md5
md5sum version >> md5
chmod -R 640 $wd
#getting everything ready for archive
#mv /opt/fs_db_backup/* /opt/fs_db_backup/tar
#create tar file for backup with absolue path
tar -czvf leo_db_backup-"$runDate".tgz /opt/fs_db_backup/*
#chmod -R 660 leo_db_backup-*
#rsync to server
#rsync -ravptx $tarpath/leo* root@server01/
#weekly retention?

Thank you!

bf_tar

BF_TAR(1)																 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.
