REV(1) User Commands REV(1)
rev - reverse lines characterwise
rev [option] [file...]
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.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.
