Storing a variable?
I'm writing a bash shell script to backup several mysql databases. This script will run on a daily basis and send a copy to a remote FTP repository. The filenames are in the format DATE.backup.sql. How do I store the DATE variable so I can delete/move/etc the file on the FTP server the next time the script runs?

Code:
#!/bin/bash

DATE=$(date +%d%b%y_%k.%M.%S)

cd /web/.hhome/mysql.backup/data
mysqldump -ubackup -ppassword --databases db1 db3 > $DATE.backup.sql

gzip -9 $DATE.backup.sql

crypt key < $DATE.backup.sql.gz > $DATE.backup.sql.enc.gz
rm -rf $DATE.backup.sql.gz

ftp -inv ftp.somehost.com<<ENDFTP
user hoover90 password
put $DATE.backup.sql.enc.gz
bye
ENDFTP

I can use pretty much any method, but it has to be done within this bash script.

Thanks!

atf-sh

ATF-SH(1)						    BSD General Commands Manual 						 ATF-SH(1)

NAME

     atf-sh [-s shell] -- interpreter for shell-based test programs

SYNOPSIS

     atf-sh script

DESCRIPTION

     atf-sh is an interpreter that runs the test program given in script after loading the atf-sh(3) library.

     atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by ATF_SHELL.  atf-sh executes the inter-
     preter, loads the atf-sh(3) library and then runs the script.  You must consider atf-sh to be a POSIX shell by default and thus should not
     use any non-standard extensions.

     The following options are available:

     -s shell	  Specifies the shell to use instead of the value provided by ATF_SHELL.

ENVIRONMENT

     ATF_LIBEXECDIR    Overrides the builtin directory where atf-sh is located.  Should not be overridden other than for testing purposes.
     ATF_PKGDATADIR    Overrides the builtin directory where libatf-sh.subr is located.  Should not be overridden other than for testing purposes.
     ATF_SHELL	       Path to the system shell to be used in the generated scripts.  Scripts must not rely on this variable being set to select a
		       specific interpreter.

EXAMPLES

     Scripts using atf-sh(3) should start with:

	   #! /usr/bin/env atf-sh

     Alternatively, if you want to explicitly choose a shell interpreter, you cannot rely on env(1) to find atf-sh.  Instead, you have to hardcode
     the path to atf-sh in the script and then use the -s option afterwards as a single parameter:

	   #! /path/to/bin/atf-sh -s/bin/bash

ENVIRONMENT

     ATF_SHELL	  Path to the system shell to be used in the generated scripts.
