shell script to run through all MainWP sites performing security scan

sec-scan.sh

# cd into the root of your MainWP dashboard site
#   Note: your wordpress install may be at a different location on your web host
#   This example is an apache host where I ssh into the root of the server
cd ../var/www/html
# run wp-cli command to list all your MainWP child sites
wp mainwp sites
# output looks like this (withou the # symbol - that is a comment indicator)

# to process all my sites I build a loop that tracks trough each site
#  by number. Fo each site it will run the command
#  wp mainwp-sucuri scan <site number> where
#  <site number> is repalce by each number in the list. 
# When entering the loop at the command line in the BASH shell your
#   Unix host will/should respond with the > symbol indicating it is 
#   expecting the script to continue with another command
#   When the BASH shell sends the 'done' command the loop os executed. 
for i in 1 3 4 5 7 8 11 13 14 16 17 18
> do
> wp mainwp-sucuri scan $i
> done

# This will cycle through all of the listed sites running the Sucuri Scan. 
# Check the security scan tab on the Manage Sites page 
# MainWP › Sites › site1.com › Security Scan
#
# To run the sucuri scan on one or two sites, enter the
#   scan command with only a single site number like so:
#    wp mainwp-sucuri scan 1  
#    wp mainwp-sucuri scan 2   

Working on automating this.
Plan to run the output of the wp mainwp sites command into a temp file,

wp mainwp sites > testfile

Next to run the formatted output through a grep / awk / cut with the correct regex to generate the listing of site numbers alone.

Almost there with these regex's

1. "^| \d{1,2} -works in regex tester, not in bash
2. cut -c3-4 textfile | grep -E "^| [0-9]{1,2}|"

The next iteration would only run the scan on site that have not been scanned in x days.

Update:

Commented out documentation lines and added instructions.
All lines preceded by a '#' are comments and are not executed by the command processor on the host.
