try on your machine

The command "echo 123 | xsel -ib" can be broken down as follows:

"echo 123": This uses the "echo" command to output the string "123" to the standard output.
"|": This is known as a pipe symbol and it is used to redirect the standard output of the command on the left to the standard input of the command on the right.
"xsel -ib": This is the command that receives the input from the previous echo command via the pipe. "xsel" is a command-line program used to access the X selection system, which is responsible for handling clipboard operations in X11-based systems. The "-ib" option specifies that the input should be set as the primary selection, which is typically the middle-click paste option in X11.

In summary, the command "echo 123 | xsel -ib" takes the string "123" and sets it as the primary selection in the clipboard using the xsel command.
