Thanks for your advice. I think your code really works. I implemted code in master_script like this :
#!/bin/sh
echo "start to backup database"
./db_backup.sh
rc=$?
echo "db_backup.sh returned ${rc}"
if [[${rc} -eq 0 ]]
then
echo "database backup successful"
./log_backup.sh
else
mail -s " database backup Unsuccessful rc=${rc}"
myemail@yahoo.com </dev/null
exit 1
fi
after db_backup-1 completed. testing exit failed. here is the error message. Please advice.
db_backup.sh returned 0
./master_script.sh[14]: [[0: not found.
database backup failed
mail: illegal option -- s
usage: mail [+] [-epqr] [-f file]

service(8) System Manager's Manual service(8)
NAME
service - run a System V init script
SYNOPSIS
service SCRIPT COMMAND [OPTIONS]
service --status-all
service --help | -h | --version
DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working
directory set to /.
The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the
invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and
stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start
command.
service --status-all runs all init scripts, in alphabetical order, with the status command.
EXIT CODES
service calls the init script and returns the status returned by it.
FILES
/etc/init.d
The directory containing System V init scripts.
ENVIRONMENT
LANG, TERM
The only environment variables passed to the init scripts.
SEE ALSO
/etc/init.d/skeleton,
update-rc.d(8),
