how to convert a file to hex and store it into another file

I make the output filename different from the original filename so we can later compare the results with the original file. The -plain option is used again to indicate that the input hex file is in plain format. This uses the -r or -revert option for reverse operation. Without the -p it would convert the text to a 16-bit word oriented traditional hexdump format, which is arguably easier to read but less compact and therefore less suitable as a transmission format and slightly harder to reverse. The -p or -plain option makes xxd use 'plain' hex format with no spaces between pairs of hex digits (i.e. This writes a hex encoding of the data in test.txt into new file test.hex. So push stack depth and 1, compare and execute, and for last element, again add the hex value and print.How to easily convert to/from plain machine-readable hexadecimal dataĮxplanation: $ xxd -plain test.txt > test.hex.d sr x Duplicate macro and push, now stack has 2 copies, pop and store top copy to register, pop and execute 2nd copy.Now the macro is in register 'r', and will execute as long as stack depth greater than 1. Useful in comparison to stack depth (z) pushed earlier. z The current top of stack now has the stack depth.It never gets used, just a way to get rid of the top of sack. sa Pop and store top of stack in register 'a'.p Print current top of stack, without popping.More explicitly I could do dc -e '10i' -f file -e '16 i 8000000' This happens after reading the file, so the file was read in base 10. -f file push contents of file to the stack.julia can be installed natively in fedora,ubuntu.

Hexadd requires integer as input so we convert strings (output of eachline) to Int with parse(Int,'string') and use that in our function. hex( value, pad) converts a value to hex, and adds padding as needed.It should be easier to read multiline: function hexadd(x) Using julia $ julia -e 'function hexadd(x) hex(( x + 0x80000000),8) end output = open('output.txt','w') open('test.txt') do inputfile for num in eachline(inputfile) write(output,'$(hexadd(parse(Int,num))) ') end end'
