This command is used to pass the value of the variable "message" as input to the "msg" command along with another variable called "select".
Here's a breakdown of what each part of the command does:
-
"echo "${message}"" - The "echo" command is used to display the value of the variable "message". By enclosing ${message} in double quotes, any spaces or special characters in the value of "message" will be preserved when it is echoed. This will be the output of the echo command.
-
"|" - The pipe symbol "|" is used to redirect the output (echoed value of "message") from the previous command (echo) as input for the next command (msg).
-
"msg ${select}" - The "msg" command is likely a custom command for sending a message or notification. The variable ${select} is being passed as an argument to this command, and it presumably determines the destination or recipient of the message.
By using this command, the value of the "message" variable is passed as input to the "msg" command, along with the value of the "select" variable. The exact functionality and purpose of the "msg" command will depend on the specific context or program it is used in.
