I suggest reading up on the
test- command (this is effectively what
[..] is). You have many possibilities to formulate various conditions on when and when not to run a script, you just need to implement them. It is far easier and in the long run less time-consuming for you to learn that (takes about 10 minutes) than to ask over and over again like you are doing now.
But first you should define what "script fails" means: does it exit with a non-zero return code? Does it write a log with an error message? Does it (not) produce a file? The secret of writing good scripts is to first make up your mind what
exactly you want to do and under which conditions, then to define
exactly what it is you want to do: "i need a file today" is less exact than "i need a file every second friday of the month" and this in turn is less exact than "i need a file every second friday only if this other file is up to date execpt for ....". Nobody here knows what you need as well as you do, so do your work first and we will gladly help with the rest.
I hope this helps.

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.
If the init script file does not exist, the script tries to use legacy actions. If there is no suitable legacy action found and COMMAND is
one of actions specified in LSB Core Specification, input is redirected to the systemctl. Otherwise the command fails with return code 2.
FILES
/etc/init.d
The directory containing System V init scripts.
ENVIRONMENT
LANG, TERM
The only environment variables passed to the init scripts.
