REV(1) User Commands REV(1) NAME rev - reverse lines characterwise SYNOPSIS rev [option] [file...] DESCRIPTION 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 then allocating the memory for the file may be unsuccessful. OPTIONS -h, --help Display help text and exit. -V, --version Print version and exit. -0, --zero Zero termination. Use the byte '\0' as line separator.
