The command "youtube-viewer -${7}" is likely used to execute a program or script called "youtube-viewer" with an argument specified as the value of the variable "${7}".
In most cases, "$" is used in command line interfaces to represent a variable. The variable name "7" is appended to the "$" sign, resulting in "${7}". The value of this variable is then passed as an argument to the "youtube-viewer" program or script.
The exact functionality of the "youtube-viewer" program or script and what the variable "${7}" represents would depend on the context or specific implementation. To fully understand the command and its purpose, more information about the program, script, and the significance of the variable "${7}" would be needed.
