标题：如何打开二进制文件 内容： 1Linux环境xxd命令如何编辑/修改二进制文件xxd工具虽然不能直接修改二进制文件，但xxd -r参数可把Hexdump文本转成二进制内容。 convert (or patch) hexdump into binary. 因此，对于要修改的二进制文件，可以先转为Hexdump文本，再通过xxd -r命令把Hexdump文本转为二进制文件。 [mycc@wen*z:~]$ xxd file1. binary0000000: 1234 0001 0000 0000 2022 0103 9900 000c . 4. .. .. . . .. .. .0000010: 22f9 0100 0041 3106 1992 6741 3106 1992 . .. .A1. .. gA1. .. 0000020: 6700 00f7 0100 001f 0933 0900 0000 0310 g. .. .. .. .3. .. .. .0000030: 4800 0000 7156 0559 71fb 0102 2c01 0130 H. .. qV.
