What is the syntax to redirect the output of a command to a file?

The syntax to redirect the output of a command to a file is achieved using the greater-than symbol followed by the filename. When using this syntax, the command's standard output is directed into the specified file. If the file does not exist, it will be created. If it already exists, its content will be overwritten with the new output from the command.

This method is essential for saving outputs of commands into files for later examination or for logging purposes. The correct answer illustrates a standard practice in Linux command-line operations for file handling.

The other options provided do not correctly represent the syntax for redirecting command output. For example, using the double greater-than symbol indicates appending output to a file instead of overwriting it, while formatting options such as "output command to filename" do not adhere to any recognized command syntax in Linux. The use of a pipe symbol in one of the options signifies the use of the output of one command as the input to another command rather than redirecting to a file.
