copyq:tldr:ccc41

This command uses a program called "copyq" to copy a JPEG image file.

Here is a breakdown of the command:

• "copyq" is the name of the program or utility being executed.
• "copy" is the command or action being performed by the program.
• "image/jpeg" is the format or MIME type of the file that is being copied.
• "<" is a redirection operator that takes the contents of the file indicated next and feeds it as input to the command.
• "${image-jpg}" is a variable or placeholder that represents the path or location of the JPEG file you want to copy.

So, in summary, this command tells the "copyq" program to copy the contents of the JPEG file specified by the variable "${image-jpg}" as image/jpeg format.
