####################################################################################################

## SNIPPET: ss core cron jobs

## we hardcode this permissions reset snippet into ss core cron jobs for redundancy ##
## chmod 700 means only the root/sudo users can execute ss core bash scripts ##

## reset permissions ##
chown root:root /var/www/ss* ## must be root:root
chmod 0700 /var/www/ss* ## 0700 means root can execute

chown root:root /var/www/bash/ss* ## must be root:root

#### 12-Cron-Monthly: Delete Lock File #############################################################
####################################################################################################

## here we delete the lock file associated with this cron job to clear the cron queue ##
## this is technically not necessary but we do it anyway for extra security ##

## delete lock file ##

#### 12-Cron-Monthly: Touch Timestamp File (End Script) ############################################
####################################################################################################

## this is a dummy timestamp file that will remember the last time this script was run ##
## it can be useful for developer reference and is sometimes used by SlickStack ##

## script timestamp ##
