xclip: Copy the output from a command to a given X11 selection area.

echo

$ echo 123 | xclip -selection ${select}

try on your machine

This command is used to send the value "123" to the clipboard using the xclip tool. The | symbol is called a pipe and it is used to pass the output of the preceding command (echo 123) as input to the following command (xclip -selection ${select}).

In this case, the echo command is used to print the string "123" to the standard output, which is then piped to the xclip command. The xclip command is responsible for taking the input value and copying it to the clipboard.

The option -selection specifies the type of selection to use. The value ${select} is a placeholder indicating that the actual selection type should be passed as an argument when using this command. The actual value of ${select} could be "primary" for the primary selection, "clipboard" for the clipboard, or other selection types supported by xclip.
