I want to convert binary data to hexadecimal, just that, no fancy formatting and all. hexdump seems too clever, and it "overformats" for me. I want to take x bytes from the /dev/random and pass them on as hexadecimal.
Preferably I'd like to use only standard Linux tools, so that I don't need to install it on every machine (there are many).

Use xxd as a filter within an editor such as vim(1) to hexdump a region marked between 'a' and 'z'. Use xxd as a filter within an editor such as vim(1) to recover a binary hexdump marked between 'a' and 'z'.
Objective: Convert a number in decimal representation to hexadecimal format in a shell script. So, let’s say that we have a variable d that has a value of 255 (decimal). To convert the representation to hex, we can use one of the following methods. The first method is by using bc.
For binary to hexadecimal use: xxd tool in linux and for binary to decimal you can use qalculate tool. For help regarding xxd type xxd --help or man xxd in Linux. Show activity on this post.
To convert the representation to hex, we can use one of the following methods. The first method is by using bc. Note that the obase tells bc the base of the output number. The input base is by default 10 or decimal.
Summary: Use the Format-Hex cmdlet to produce hexadecimal output. How can I use Windows PowerShell to put data in a binary key in the registry?
Perhaps use xxd:
% xxd -l 16 -p /dev/random 193f6c54814f0576bc27d51ab39081dc Watch out!
hexdump and xxd give the results in a different endianness!
$ echo -n $'\x12\x34' | xxd -p 1234 $ echo -n $'\x12\x34' | hexdump -e '"%x"' 3412 Simply explained. Big-endian vs. little-endian :D
