In computing , “ dd ” is a common program for Unix and Unix-like operating systems whose primary purpose is to "convert and copy a file." [ 1 ] On Unix, device drivers for hardware (such as hard disks ) and special device files (such as /dev/zero and /dev/random ) appear in the file system just like normal files; dd can also read from (and in some cases write to) these files. As a result, dd can be used for tasks such as backing up the boot sector of a hard drive, and obtaining fixed amount of random data. The dd program can also perform conversions on the data as it is copied, including byte order swapping and conversion to and from the ASCII and EBCDIC text encodings. [ 2 ]

Improve your scripts argument processing wih getopt and getopts. Both "getopt" and getopts are tools to use for processing and validating shell script arguments. They are similar, but not identical. More confusingly, functionality may vary from place to place, so you need to read the man pages carefully if your usage is more than casual.
