How can I diff 2 files while ignoring differences in hexadecimal values within?

I have 2 files, they are different versions of the same thing. However, one has different hexadecimal values, memory addresses, than the other.

Is there a diff command or a filter I can use to diff with so that the output will only be lines that are different after ignoring different hex values?

# diff output I would like to filter: - .. 0x000000010e428bb4 _swift_stdlib_bridgeErrorToNSError + 388", - .. 0x000000010e3f0347 swift_dynamicCast + 2455", - .. 0x000000010e3f051a swift_dynamicCast + 2922", + .. 0x00000001013f2bb4 _swift_stdlib_bridgeErrorToNSError + 388", + .. 0x00000001013ba347 swift_dynamicCast + 2455", + .. 0x00000001013ba51a swift_dynamicCast + 2922",

Solution

  • Just use sed to rewrite the hex numbers. Something like:

    sed 's/0x[0-9a-f]*/HEX/g'

    Which given input like:

    .. 0x000000010e428bb4 _swift_stdlib_bridgeErrorToNSError + 388",

    Results in:

    .. HEX _swift_stdlib_bridgeErrorToNSError + 388",

    You could combine this with your diff statement like (assuming bash):

    diff <(sed 's/0x[0-9a-f]*/HEX/g' file1) <(sed 's/0x[0-9a-f]*/HEX/g' file2)
