How to reverse a string in command line
command
echo 'hello world' | revresult
dlrow ollehrev
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.
