dd seem an unfriendly command, but if you start to use it,
you’ll see that it’s a powerful command able to do many
different things, backup a partition, CD or USB stick for
example or do some simple tests on the speed of your disks or
your CPU. The man page say: dd is an application that will
“convert and copy a file” But let’s see some trick with it. The
GNU clone of dd is part of fileutils package, and i’d say that
any Linux should have it installed. Unlike most Unix commands,
dd uses a keyword=value format for its parameters. The dd
utility copies the specified input file to the specified output
with possible conversions. The standard input and output are
used by default. The input and output block sizes may be
specified to take advantage of raw physical I/O. Sizes are
specified in bytes; a number may end with k, b, or w to specify
multiplication by 1024, 512, or 2, respectively. Numbers may
also be separated by x to indicate multiplication. So the basic
options are: if= file Specifies the input path. Stan
