SYNOPSIS

9       rev [option] [file...]
10

DESCRIPTION

12       The  rev utility copies the specified files to standard output, revers‐
13       ing the order of characters in every line.  If no files are  specified,
14       standard input is read.
15
16       This  utility  is  a line-oriented tool and it uses in-memory allocated
17       buffer for a whole wide-char line.  If the input file is huge and with‐
18       out line breaks than allocate the memory for the file may be unsuccess‐
19       ful.
