REV(1)                        User Commands                       REV(1)

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

              Display version information and exit.

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