The "rev" command is used to reverse the characters of each line of a file or input provided through the standard input. For example, if the input is "hello world", then the output of the "rev" command would be "dlrow olleh". Some common options for the "rev" command are: - -V or --version: displays the version information and exits
- -h or --help: displays the help information and exits
- -n: do not output the trailing newline
- -r: reverse the entire string instead of each line in the input
- -s: specify a separator character to use (default is newline) An example usage of the "rev" command is: ```
echo "hello world" | rev
