This is a 2 part question.

Scenario: This script is on a cronjob. If a folder does not exist, the system sends us an email that opens a ticket which notifies us that the folder is not available. We manually have to log in and remove the preceding folder atm.

I would like for us to be able to execute the script manually and remove the preceding folder by pressing "Y" or to continue by pressing the "Enter" key, while we are logged in and execute the script manually.

This is what I have so far ...

 #-- check to see if cache folder exists
 echo "Checking to see if ...";
 echo "$wDir/$client%//.ftp-vendor-scripts/cache exists ... "; echo ""; >> "$log"

 if [ ! -d "$wDir"/"$client%/"/.ftp-vendor-scripts/cache ]; then
 echo "Directory - $wDir/$client%//.ftp-vendor-scripts/cache DOES NOT exists - Failed ..." >> "$log";

 if [ ******** this script is being executed manually ******* ]; then
 echo "Would you like to delete the $wDir/$client%//.ftp-vendor-scripts folder?"
 echo "Press "Y" to delete the $wDir/$client%//.ftp-vendor-scripts."
 echo "Press "Enter" to continue without deleting the .ftp-vendor-scripts folder."
 else
 echo "Directory - $wDir/$client%//.ftp-vendor-scripts/cache DOES NOT exists - Failed ..." | mail -s "$wDir/$client%//.ftp-vendor-scripts/ca$
 fi

 else
 echo "Directory - $wDir/$client%//.ftp-vendor-scripts/cache exists - Success ..." >> "$log";
 fi

You need something like this:

#!/usr/bin/env sh

if [ -t 1 ]
then
 interactive=1
else
 interactive=0
fi


if [ "$interactive" -eq 1 ]
then
 printf "interactiven"

 while true
 do
 printf "Rm directory? "
 read -r reply
 if [ "$reply" = "y" ]
 then
 printf "directory will be removedn"
 break
 elif [ "$reply" = "n" ]
 then
 printf "directory will not be removedn"
 break
 else
 printf "Uknown reply - it must be either y or nn"
 fi
 done

else
 printf "non interactiven"
fi

The above script is POSIX-compliant and checked for errors with shellcheck. It will check if it runs in interactive or non interactive mode, possibly via cron and will act accordingly. I've tested it with bash, dash, Busybox ash and FreeBSD.
