The hexdump command converts any file to hex values.
But what if I have hex values and I want to reverse the process, is this possible?
There is a similar tool called xxd
. If you run xxd
with just a file name it dumps the data in a fairly standard hex dump format:
# xxd bdata
0000000: 0001 0203 0405
......
Now if you pipe the output back to xxd
with the -r
option and redirect that to a new file, you can convert the hex dump back to binary:
# xxd bdata | xxd -r >bdata2
# cmp bdata bdata2
# xxd bdata2
0000000: 0001 0203 0405
