ExifTool – Chack Meta Data Of Images Using Linux & Termux


ChackMeta Data Of Images – In this article, we will discover various ways to read, write, and manipulate data with metadata recorded in various file types. To achieve this, we will be using a tool known as “ExifTool”. EXIF is a summary of the Variable Image File Format and is the standard for adding metadata to certain types of files.

ExifTool was developed by Phil Harvey. It is Perl’s independent library combined with the command line implementation full of reading, writing and decryption metadata in a wide range of files, especially JPEG images. This metadata may include a host of information such as camera performance, file type, permissions, file size, etc., although it provides additional information about the image, such as exposure, shutdown speed and whether flash is turned on or not. ExifTool probably gives us an easy way to extract metadata from files, as it is free and is an open source program.

Therefore, we have included a tool in our system. Let’s take a closer look



Usage of Exiftool Termux & Linux :-

To remove all file metadata, we just need to execute the command given below:

exiftool (filename)

From the image below, you can see that we have all the information taken from our image file from the most basic to advanced. ChackMeta Data Of ImagesChackMeta Data Of ImagesHowever, if we need to capture the id and exif tags in the Hexa-Decimal format, or we need to use the following command:

exiftool -H (filename)

From the image below, we can see that there is a lot of information stored inside these Exif tags.ChackMeta Data Of Images

View Common Meta-Data Information :- Exiftool

Now execute the command below that will provide us with the exit of standard Exif tags for an image file.

exiftool -common (filename.jpg)




GPS Locatio Co-ordinates Information :-

The photographs we capture using our smartphones or camera have GPS coordinates embedded. Photos taken with our mobile phones or camera have GPS links embedded as metadata in image files. To find this, we just need to turn off the command given below. ChackMeta Data Of Images.

 exiftool  (filename) | grep GPS 




View Meta Data Using Specific Keywords :-

The following command will help us extract the metadata information associated with certain keywords.

 exiftool  "-*keyword*" (filename)


Saving outputs in Multiple Format :- Exiftool

We can also export our exifdata to a text file similar to an HTML output. To accomplish this, we just need to do the following instructions

 exiftool (filename) > (outputexif.txt)

Additionally, we can also monitor our output by opening it in any text editor or by simply using a command

 cat (filename)

View ExifData from a Video file :-

ExifTool not only extracts metadata from the jpg file format but can read and write to various files. To find out more click here.

We will now extract all metadata details from the mp4 video file. To extract this, we will use the basic exiftool command i.e.

 exiftool (filename.mp4)


Removing Meta-Data Information :-

We’ve only extracted or decrypted EXIF ​​data so far, but what if we want to delete or delete all metadata from the image file? Just issue a command below, let’s see how this works:

exiftool -all= (filename)

Displays 1 uploaded image files. EXIF data for “test.jpg” successfully deleted. Although we may try to remove metadata from “test.jpg” again, this is why we get the basic image information and some of it is deleted.ChackMeta Data Of Images

The conclusion

This was a complete guide to the use of Exiftool as a metadata extractor. It is easy to use and easy to use due to its use of a simple command line. It has therefore become one of the best tools for extracting metadata data from various file formats.
