|

|
|
The \fBrev\fP 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 then allocating the memory for the file may be unsuccessful.
