The command "exiftool -All= ${filename1 filename2 ---}" is used to remove all metadata from one or multiple files using a tool called ExifTool.
Here's a breakdown of the different components of the command:
-
"exiftool": This is the actual command-line tool called ExifTool. It is used for reading, writing, and manipulating metadata information in various file formats.
-
"-All=": This is an option or argument provided to the ExifTool command. The "-All=" argument tells ExifTool to remove all metadata from the specified file or multiple files.
-
"${filename1 filename2 ---}": This part of the command specifies the file or files from which you want to remove the metadata. You can provide one or more filenames separated by spaces. The "---" is used to indicate the end of the file list if you want to add more files afterward.
For example, if you want to remove all metadata from a single file named "image.jpg," you would use the command: "exiftool -All= image.jpg".
If you want to remove metadata from multiple files, you can provide their filenames separated by spaces, like this: "exiftool -All= file1.jpg file2.jpg file3.jpg".
