Example use: ./bin2hex binary_file_1 | ./hex2bin - > binary_file_2. diff -s binary_file_1 binary_file_2. This works with busybox, but hex2bin is unfortunately limited by the maximum length of the argument given to xargs, so this method will only work for small files (less than 32 KiB on my desktop system). Share.
So if your ibase is 2, then if you set your obase to 10, it won't do anything, as 10 in binary is 2. Hence you need to use hexadecimal notation. So binary to decimal would be (watch that obase is A) Binary to decimal: $> echo 'ibase=2;obase=A;11110001011010'|bc. 15450.
Okay, in the light of what you have said and what I understood, I have a couple of suggestions to you. The first one, converts each hex line into a new binary line and puts a line break at the end of each line. here is that solution: len=${#line} binline="". index=1. while [ ${index} -le ${len} ] do.
I don't think there's a reasonable (and reasonably fast) way to convert hexadecimal to binary using only POSIX tools. It can be done fairly easy in Perl. The following script converts hexadecimal to binary, ignoring any input character that isn't a hexadecimal digit. It complains if an input line contains an odd number of hexadecimal digits.
The best way to understand this is that everything is binary. What you are trying to do is produce an ascii string of binary digits that represent the binary of the original ascii codded message. Therefore it is irrelevant that the original is ascii coded (well almost, as long as it is). Now you just need a tool that can print the binary as text.
Because you are setting the input base first, then when you set the output base, the 16 will be interpreted according to the input base (2). It appears that the 6 in 16 is simply interpreted is a binary 1 bit in this case, and so the output base gets set to binary 11 or decimal 3.
Binary test data 1GB, discussed here, is created by. dd if=/dev/urandom of=sample.bin bs=64M count=16 Split by byte position. Please, see the thread about this here. I think this is the most appropriate way to do the split if the byte offset is fixed. You need to determine the locations of the first two event headers and count the size of the ...
If the data you're viewing is mostly text with occasional binary, you might find the -v option to cat(1) convenient: $ printf 'here is\x00\x01some text\x15\x16with the odd bit\x80\x81of binary mixed in' | cat -v here is^@^Asome text^U^Vwith the odd bitM-^@M-^Aof binary mixed in Non-printing bytes ≤ 0x7f are displayed with control-character ...
Before everything though it must go through little endian to big endian conversion (I may be confusing the two but my example below should clarify) EXAMPLE: Hex Value: 0080 After Conversion: 8000. Hex Value: 9800 After Conversion: 0098. Hex Value: 1234 After Conversion: 3412. I believe that this is a 16 bit hex variable as it is always 4 digits.
"binary" isn't an encoding (character-set name). iconv needs an encoding name to do its job. The file utility doesn't give useful information when it doesn't recognize the file format. It could be UTF-16 for example, without a byte-encoding-mark (BOM).
