coproc:tldr:de3e5

This command sets up a coprocess, a named pipe that allows communication between a shell script and a background command. Here is a breakdown of the components of the command:

1. coproc: This is the keyword used to establish a coprocess in the shell script.

2. ${name}: name is a variable that holds the name of the coprocess. It can be any valid variable name that you want to use to refer to this specific coprocess.

3. { ${command1; command2; ---}; }: The curly braces {} define a group of commands that will run in the coprocess. The individual commands inside the curly braces are separated by semicolons. command1, command2, etc., are actual commands that will be executed in the coprocess.

So, when this command is executed, it creates a coprocess named ${name} (could be any variable name you choose) and runs the specified commands within the curly braces as the code executed by the coprocess.

Note that the coprocess runs in the background, allowing the main shell script to continue executing its commands while also being able to communicate with the coprocess through the named pipe.
