提取“明文” HEX文件使用Perl的头文件 [英] Extracting "plaintext" header from HEX file using Perl

问题描述

使用HEXedit，这就是我所看到的文件，它显示了明文头文件，我想提取并转换为明文文件。 ，它在一个文件中：

  3a40  -  31 65 33 38 00 00 00 00 00 00 00 00 00 00 00 00  - 1e38 ............ 
 3a50  -  00 00 00 00 00 00 00 00 00 00 0a 00 74 00 65 00  -  ............ te 
 3a60  -  78 00 74 00 2f 00 61 00 73 00 63 00 69 00 69 00  -  x.t./.a.s.c.i.i。 
 3a70  -  00 00 18 00 61 00 66 00 66 00 79 00 6d 00 65 00  -  .... affyme 
 3a80  -  74 00 72 00 69 00 78 00 2d 00 61 00 72 00 72 00 -  trix-.arr 
 3a90  -  61 00 79 00 2d 00 62 00 61 00 72 00 63 00 6f 00  -  ay-.barco 
 3aa0  -  64 00 65 00 00 00 64 00 40 00 35 00 32 00 30 00  -  d.e ... d。@。5.2.0。 
 3ab0  -  38 00 32 00 36 00 30 00 30 00 39 00 31 00 30 00  -  8.2.6.0.0.9.1.0。 
 3ac0  -  37 00 30 00 36 00 31 00 31 00 31 00 38 00 31 00  -  7.0.6.1.1.1.8.1。 
 3ad0  -  31 00 34 00 31 00 32 00 31 00 33 00 34 00 35 00  -  1.4.1.2.1.3.4.5。 
 3ae0  -  35 00 30 00 39 00 38 00 39 00 00 00 00 00 00 00  -  5.0.9.8.9 ....... 
 3af0  -  00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  -  ................ 
 3b00  -  00 00 00 00 00 00 00 00 00 00 00 00 00 00 0a 00  -  ... ............. 
  

这是我输出的结果喜欢获得：

$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $'

解决方案

使用 iconv 命令。像这样的东西应该可以工作：

  tail -c +6 input.txt | iconv -f UTF16 -t ASCII> output.txt 
  

然后分割空字节。 p>

Have a file that appears to have plaintext headers in them that I would like to extract and convert to plaintext.

Using HEXedit, this is what I'm seeing, which is in a file:

3a40 - 31 65 33 38 00 00 00 00 00 00 00 00 00 00 00 00 - 1e38............
3a50 - 00 00 00 00 00 00 00 00 00 00 0a 00 74 00 65 00 - ............t.e.
3a60 - 78 00 74 00 2f 00 61 00 73 00 63 00 69 00 69 00 - x.t./.a.s.c.i.i.
3a70 - 00 00 18 00 61 00 66 00 66 00 79 00 6d 00 65 00 - ....a.f.f.y.m.e
3a80 - 74 00 72 00 69 00 78 00 2d 00 61 00 72 00 72 00 - t.r.i.x.-.a.r.r
3a90 - 61 00 79 00 2d 00 62 00 61 00 72 00 63 00 6f 00 - a.y.-.b.a.r.c.o.
3aa0 - 64 00 65 00 00 00 64 00 40 00 35 00 32 00 30 00 - d.e...d.@.5.2.0.
3ab0 - 38 00 32 00 36 00 30 00 30 00 39 00 31 00 30 00 - 8.2.6.0.0.9.1.0.
3ac0 - 37 00 30 00 36 00 31 00 31 00 31 00 38 00 31 00 - 7.0.6.1.1.1.8.1.
3ad0 - 31 00 34 00 31 00 32 00 31 00 33 00 34 00 35 00 - 1.4.1.2.1.3.4.5.
3ae0 - 35 00 30 00 39 00 38 00 39 00 00 00 00 00 00 00 - 5.0.9.8.9.......
3af0 - 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 - ................
3b00 - 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0a 00 - ................

and this is the output I'd like to get:

text/ascii  affymetrix-array-barcode d@52082600910706111811412134550989

解决方案

Try with the iconv command. Something like this should work:

tail -c +6 input.txt | iconv -f UTF16 -t ASCII >output.txt

Then split on the null bytes.
