The command jpegtran -flip ${select} ${path-to-image-jpg} > ${path-to-output-jpg}
is a command-line command for flipping or rotating a JPEG image using the jpegtran
tool.
Here is what each part of the command does:
jpegtran
is the name of the command-line tool used to manipulate JPEG files.-flip
is an option or flag provided tojpegtran
which specifies that the image should be flipped vertically.${select}
is a variable that should be replaced with the specific parameters or arguments required by thejpegtran
tool. The purpose of this variable depends on how it is defined or used in the context where this command is used.${path-to-image-jpg}
is another variable that should be replaced with the path to the input JPEG image file that you want to flip.>
is a redirection operator that is used to redirect the output of the command to a file instead of displaying it on the command-line interface. In this case, it means redirecting the output of thejpegtran
command to a file.${path-to-output-jpg}
is a variable that should be replaced with the path and file name of the output JPEG image file where the flipped image will be saved.
In summary, this command flips a specified JPEG image vertically using the jpegtran
tool and saves the flipped image to another JPEG file specified by the ${path-to-output-jpg}
variable. The ${select}
variable and its purpose depend on how it is implemented in the specific context where this command is used.
