NAMErev − reverse lines characterwise
SYNOPSISrev [option] [file...]
DESCRIPTIONThe 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 then allocating the memory for the file may be unsuccessful.
OPTIONS−h, −−help Display help text and exit. −V, −−version Print version and exit.
