Command Result

What happens when it runs

Shell behavior

Primary Effect

Writes to file. The command sends content into the output file instead of printing the final result to the terminal.

Terminal Expectation

A successful run is usually quiet. Verify the destination file after execution rather than expecting visible stdout.

Troubleshooting

One of the input files does not exist

Solution: Check each input path before running the command.

The destination file or directory is not writable

Solution: Verify write permissions on the target path and parent directory.

Shell redirection points to the wrong file

Solution: Double-check the output path before executing, especially when overwriting with >.

Command Breakdown

sudo: Base Command; The executable that performs this operation. Here it runs Arptables Save before the shell applies any redirect operators.
>: Output Redirection; Writes the command output to the output file, replacing any existing content.
<path/to/file>: Destination Path; The file that receives the final written output.
