try on your machine
The given command is executing the "jpegtran" command-line tool, which is used for manipulating JPEG images. Here's a breakdown of the command:
- "jpegtran": This is the name of the command-line tool being executed.
- "-rotate": This is an option or flag for the "jpegtran" command that specifies the rotation operation.
- "${select}": This is a placeholder for a rotation value. It should be replaced with an angle in degrees (e.g., 90, 180, etc.) to determine the rotation angle for the image.
- "${path-to-image-jpg}": This is a placeholder for the path to the input JPEG image file that you want to rotate.
- ">": This is a redirection symbol that specifies the output of the command should be saved to a file.
- "${path-to-output-jpg}": This is a placeholder for the desired path and file name where you want to save the rotated JPEG image.
To use this command, you need to replace the placeholders with appropriate values. For example:
jpegtran -rotate 90 input.jpg > output.jpg
This will rotate the "input.jpg" image by 90 degrees clockwise and save the result as "output.jpg".

never run a command you are not sure if it is safe.
