Getting Full File Path of Just Opened File in Mac OS Terminal using a Script

Introduction

If you're a Mac OS user working in the terminal, you might find yourself needing to get the full file path of a file you just opened. This can be particularly useful when working with scripts that require the full file path as an input.

In this article, we'll explore how to write a script that retrieves the full file path of a just-opened file in Mac OS Terminal. We'll cover key concepts, provide detailed context, and include subtitles, paragraphs, and code blocks to help you understand and implement the solution.

Key Concepts

To retrieve the full file path of a just-opened file in Mac OS Terminal, we'll use the following concepts:

1. AppleScript: A scripting language developed by Apple that allows you to automate tasks and interact with the operating system.
2. osascript: A command-line tool that allows you to run AppleScript code from the terminal.
3. Environment Variables: Variables that contain information about the system and environment in which a script is running.

Retrieving the Full File Path

To retrieve the full file path of a just-opened file in Mac OS Terminal, we'll write an AppleScript that uses the path to command to get the file path of the frontmost Finder window. We'll then use the osascript command to run the AppleScript from the terminal.

Here's an example AppleScript that retrieves the full file path of the frontmost Finder window:

tell application "Finder"
    set theFile to (POSIX path of (item 1 of (get selection)))
end tell

set theText to theFile

This AppleScript first tells Finder to get the selection (i.e., the currently selected file or folder). It then gets the POSIX path of the first item in the selection (i.e., the full file path of the file or folder). Finally, it sets the theText variable to the full file path.

To run this AppleScript from the terminal, we can use the osascript command like this:

osascript -e 'tell application "Finder" to set theFile to (POSIX path of (item 1 of (get selection)))' -e 'set theText to theFile'

This command uses the -e flag to specify the AppleScript code to run. The first -e flag specifies the code to get the selection and the full file path, and the second -e flag specifies the code to set the theText variable.

Using Environment Variables

To make the full file path available to other scripts or commands, we can set an environment variable using the export command. For example, we can modify the previous osascript command to set the FILE_PATH environment variable like this:

FILE_PATH=$(osascript -e 'tell application "Finder" to set theFile to (POSIX path of (item 1 of (get selection)))' -e 'set theText to theFile' -e 'return theText')

This command uses command substitution ($(...)) to set the FILE_PATH variable to the output of the osascript command.

Using the Full File Path in a Script

Now that we have the full file path available as an environment variable, we can use it in a script. For example, we can modify a .sh script to accept the full file path as an argument and print it to the console like this:

#!/bin/bash

echo "The full file path is: $FILE_PATH"

This script uses the echo command to print the full file path to the console.
