The given command nu --commands "${echo 'nu is executed'}"
has two main components:
-
nu
: It is the name or path of an executable program or script. -
--commands "${echo 'nu is executed'}"
: This part of the command passes a string argument to the program or script being executed (nu
in this case).Within this argument, there is a subcommand enclosed in single quotes (
'nu is executed'
):echo 'nu is executed'
. Theecho
command is used to print the specified message to the standard output. In this case, it will displaynu is executed
. The output ofecho
is then enclosed within double quotes ("${...}"
), which allows it to be expanded and treated as a single argument.So, when the command
nu --commands "${echo 'nu is executed'}"
is executed, it will run thenu
program or script and provide the outputnu is executed
as the value of the--commands
argument. The behavior of thenu
program or script with this command depends on its specific implementation and purpose.
