# Use this script to combine multiple scripts into one script for deploying to a remote machine or management system like Workspace ONE UEM

# Directions:
# create an array of files to combine
# example: files=("bashFunctionLibrary.sh" "bashFunctionLibrary.sh")
# decide on a destination file name
# example: destination="fullScript.sh"
# run the script
# example: ./prepScript.sh "${files[@]}" "$destination"
# Notice how you must use the "${files[@]}" syntax to pass the array to the script


# take lines from the sfiles starting at ###SOF### and ending at ###EOF### and add them to the dfile
# if the dfile does not exist it will be created
# if the dfile does exist it will be overwritten

# note - do not include teh shebang line in the source files since it will be added to the destination file automatically

# $1 - source files array
# $2 - destination file
