Prerequisites

Before installing ExifTool on your Ubuntu system, ensure you have the following:

Ubuntu System: This guide applies to various versions of Ubuntu, including LTS releases.
Sudo Privileges: Administrative access is required to install packages.
Basic Terminal Knowledge: Familiarity with terminal commands will be helpful.

Step 1: Update Your System

Start by updating your system’s package index to ensure you have the latest information about available packages. Open your terminal and run the following command:

sudo apt update

Step 2: Install ExifTool

ExifTool is available in the default Ubuntu repositories, making installation straightforward. To install ExifTool, run the following command:

sudo apt install exiftool

Once the installation is complete, you can verify it by checking the version:

exiftool -ver

You should see the installed version number displayed in the terminal.

Step 3: Basic Usage of ExifTool

Now that you have ExifTool installed, let’s explore some basic commands to get you started.

1. Viewing Metadata

To view the metadata of a file, use the following command:

exiftool yourfile.jpg

Replace yourfile.jpg with the path to your image file. ExifTool will display all available metadata associated with that file.

2. Editing Metadata

You can modify metadata using ExifTool. For example, to change the title of an image, use:

exiftool -Title=”New Title” yourfile.jpg

This command updates the title metadata field of yourfile.jpg to “New Title”.

3. Batch Processing

ExifTool allows you to process multiple files at once. For instance, to change the title of all JPEG files in a directory, you can use:

exiftool -Title=”New Title” *.jpg

This command will update the title for all JPEG files in the current directory.

4. Removing Metadata

To remove specific metadata from a file, use the -all= option:

exiftool -all= yourfile.jpg

This command removes all metadata from yourfile.jpg. Use this with caution, as it permanently deletes the metadata.

5. Copying Metadata Between Files

You can also copy metadata from one file to another. For example, to copy all metadata from source.jpg to destination.jpg, use:

exiftool -TagsFromFile source.jpg destination.jpg

This command copies all metadata from the source file to the destination file.

6. Extracting Specific Metadata

If you only want to view specific metadata tags, you can specify them directly. For example, to view the camera model used to take a photo, use:

exiftool -Model yourfile.jpg

Step 4: Advanced Features

ExifTool offers a wide range of advanced features for more experienced users. Here are a few examples:

Creating Reports: You can generate detailed reports of the metadata in a specific format:

exiftool -csv -r /path/to/directory > metadata_report.csv

This command will create a CSV report of all metadata in the specified directory.

Conditionally Writing Metadata: You can write metadata based on certain conditions using Perl expressions. For example, to set a common copyright notice for all files in a directory:

exiftool -Copyright=”Your Copyright Notice” -ext jpg /path/to/directory

This command sets the copyright field for all JPEG files in the specified directory.
