Redirect stderr

${command}

$ ${command} 2> ${file}

try on your machine

This command consists of two parts, command and file.

${command} refers to a variable or placeholder that represents the specific command you want to execute. It could be any valid command or script.

2> is a redirection operator in Unix-like systems that redirects the error output (stderr) of the command. In this case, it redirects error messages to a file, not to the regular output (stdout).

${file} is another variable or placeholder that represents the name or path of the file where the error output will be redirected. It could be any valid file name or path.

Putting it all together, this command executes ${command} and redirects any error output it produces to ${file}. This allows you to separate and capture error messages separately from the regular output.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
