How can I create a Finder alias in a bash script that reads arguments from the command-line?

I'd like to write a bash script that takes 2 inputs:

1. path to actual file
2. path of a Finder alias file (not a unix link) to be created that refers to 1.

The bash script should pass these inputs to an automation script that creates the alias.

I've seen How to use AppleScript in a bash script to create an alias for an app? but I have not been able to adapt it for my goal.

How can I do this?

Solution 1:

With minimal error handling:

#!/bin/sh

[ -f "$1" ] || exit 1
[ "$2" ] || exit 1

alias=$(basename "$2")

/usr/bin/osascript <<EOF
tell application "Finder"
    set myapp to POSIX file "$1" as alias
    make new alias to myapp at Desktop
    set name of result to "$alias"
end tell
EOF

mv ~/Desktop/"$alias" "$2"
