dumping binary file

hexdump -v -e '/1 "%X\n"' binary.file > binary.file.dump

Dumps the contents of the binary file to the text file. Each byte of the binary file corresponds to one line id the text file. Each byte of the binary file is represented by a hexadecimal number in the text file.

setting blocks of disk images to zero

((dd count\=208 if\=image.iso) && (dd count=1 if=/dev/zero && (dd skip=209 if=image.iso))) > image2.iso

Creates a copy of the file called image.iso and saves the result to the file image2.iso; instead of the 209th block of the original file, zeros will be saved to the destination file. The block size is 512 bytes.

exploring the strings contained in a binary file

strings image.iso | less
