The command you provided is for using the jpegoptim
program with multiple image files.
jpegoptim
is a command-line utility that is used to optimize JPEG files. It works by reducing the file size of JPEG images without significantly affecting the image quality. One common optimization technique applied by jpegoptim
is progressive encoding.
The options and arguments used in this command are as follows:
--all-progressive
: This option tellsjpegoptim
to convert the input images to progressive JPEG format. Progressive JPEGs load in a series of scans, which allows web browsers to display a low-resolution version of the image quickly and then gradually improve the image quality. This option can help in achieving faster image loading on websites.${image1-jpeg}
,${image2-jpeg}
,${imageN-jpeg}
: These are placeholders for the actual image file paths or filenames. You need to replace them with the specific paths or filenames of the JPEG images you want to optimize. You can list multiple images separated by spaces.
For example, if you have three JPEG image files named "image1.jpeg", "image2.jpeg", and "image3.jpeg" in the current directory, you can optimize them all and convert them to progressive JPEGs using the following command:
jpegoptim --all-progressive image1.jpeg image2.jpeg image3.jpeg
Make sure you have jpegoptim
installed on your system before using this command.
