rev: Reverse an entire file and print to `stdout`.

$ rev ${filename}

try on your machine

The command "rev ${filename}" is used to reverse the characters in a file named "filename" and display the result in the terminal or command prompt.

Here's how it works:

"rev" is a command-line utility in Unix-based systems that reverses the characters in a file. It reads the file line by line, reverses each line, and outputs the reversed lines.
"${filename}" is a placeholder for the actual file name. In order to use this command, you need to replace "${filename}" with the name or path of the file you want to reverse.

For example, if you have a file named "example.txt" and you want to reverse its content, you would use the command "rev example.txt". The command will read the content of "example.txt", reverse the characters in each line, and display the result in the terminal or command prompt.
