fish: Execute specific commands from `stdin`.

${echo

$ ${echo "echo 'fish is executed'"} | fish

try on your machine

This command is using a shell pipeline in a bash environment. Let's break it down step by step:

${echo "echo 'fish is executed'"}: This is command substitution syntax in bash. The content within ${} is evaluated and the result is substituted in place. In this case, the command being evaluated is echo "echo 'fish is executed'". So, the result of this command substitution would be echo 'fish is executed'.
|: This is known as the pipe symbol and it is used to connect two commands in a pipeline. It takes the output from the preceding command and feeds it as input to the succeeding command.
fish: This is a command to execute the fish shell. In this case, the output of the previous command substitution is being passed as input to the fish shell.

Putting it all together, the purpose of this command is to execute the fish shell and pass the command echo 'fish is executed' as input to it. Therefore, when you run this command, it will print the phrase "fish is executed" in the fish shell.
