NAME         top

       rev - reverse lines characterwise

SYNOPSIS         top

       rev [option] [file...]

DESCRIPTION         top

       The rev utility copies the specified files to standard output,
       reversing the order of characters in every line. If no files are
       specified, standard input is read.

       This utility is a line-oriented tool and it uses in-memory
       allocated buffer for a whole wide-char line. If the input file is
       huge and without line breaks than allocate the memory for the
       file may be unsuccessful.

OPTIONS         top

       -V, --version
           Display version information and exit.

       -h, --help
           Display help text and exit.
