Would #! /bin/sh - shebang prevent from execution on other operating systems? How to create shell agnostic portable script?

If I include a shebang line in my script like following #! /bin/sh Would it prevent from execution on other operating systems like Windows which may not have sh in bin folder? Is this better to omit shebang line to make a portable script? How to write a operating system agnostic, shell agnostic, portable script which would execute in the same way in all operating systems or shells? If the script has to be executed the same way on Mac OS, Windows, Ubuntu, any other Linux or any other operating systems? --- Assumptions. I assume to prepare a script for a workshop where workshop participants may use different operating systems and may have different shells; I share preparation notes to install all needed tools like jq, sed, sfdx, curl and I assume the script would run the same way on all machines and all the operating systems. I assume workshop participants mainly use Mac OS, Windows, Ubuntu. Also I assume that participants may install Git Bash tool on Windows if there is no posix compatible shell. --- The script itself unwrap2.sh verbose=$1 # deploy data cloud Data Kit sf project deploy start -d dc # unwrap Data Kit components x=$(sf apex run -f scripts/unwrap.apex --json | jq '.result.logs' -r) x1=${x#*EXECUTION_STARTED} x2=${x1#*Result is \(success): } if [[ "$verbose" = "verbose" ]];
