This command is a shell command that uses the echo
command to print the value of the variable ${input}
to the file descriptor specified by the value of the variable $${{name}[1]}
.
Let's break down the command step by step:
-
${input}
: This is a shell variable. The value of this variable will be printed by theecho
command. -
"${input}"
: The value of the${input}
variable is enclosed in double quotes. This is done to ensure that any special characters or spaces in the value are preserved during the echo command. -
>&"$${{name}[1]}"
: This portion has two parts:-
$${{name}[1]}
: This is a shell variable${name}
followed by[1]
. It is enclosed in double dollar sign$$
to escape the first dollar, so that it is treated as a literal dollar sign. The[1]
indicates that we want the second element of the array variable${name}
(assuming${name}
is an array variable). -
>&
: This is a redirection operator in the shell.>&
redirects the standard output of the command (echo "${input}"
in this case) to the specified file descriptor.
-
So, overall, the command takes the value of the ${input}
variable, encloses it in quotes to preserve special characters, and then redirects the output to the specified file descriptor, which is determined by the value of the array variable ${name}[1]
.
