create an ascii hexdump from binary or text files

, to take a look into format details like line endings, with sfk hexdump for Windows, Mac OS X, Linux and Raspberry Pi.
- download the free Swiss File Knife Base from Sourceforge.
- open the Windows CMD command line, Mac OS X Terminal or Linux shell.
- OS X : type mv sfk-mac-64.exe sfk and chmod +x sfk then ./sfk
- Linux: type mv sfk-linux-64.exe sfk    and chmod +x sfk then ./sfk
  OS X and Linux syntax may differ, check the help within the tool.
sfk hexdump [options] dir .ext1 .ext2 .ext3
sfk ... +hexfile

create human-readable hexdump of binary data.

   -showle  highlights line end characters CR and LF.
            this is default with pure text data.
            you may also add "le" to the command name.
   -nole    do not highlight line end characters.
   -wide    dumps 32 input bytes per line.
   -lean    dumps 16 input bytes per line.
   -post    reduced format e.g. for forum posts
   -min     minimal format with alnum only text
   -nofile  or -nofilenames does not list the filename(s).
   -rawname prints filename without :file prefix
   -pure    lists flat hex characters:
   -hexsrc  lists hex comma separated values:
   -decsrc  lists decimal comma separated values:
   -nolf    do not add linefeeds with -pure, -hex/decsrc.
   -raw     same as -nofile -pure -nolf.
   -off[set] n1    dump from offset n1 to file end.
                   n1 can be negative, for example
                   -off=-100 dumps last 100 bytes of file.
   -last n1        same as -offset -n1
   -offlen n1 n2   dump from offset n1 only n2 bytes.
   -notrail     no trailing comma "," at end of hex/dec src
   -norectrail  no trailing comma at end of every src record
   -recsize n   only with -hex/decsrc, -pure or -flat:
            change no. of input bytes dumped per record.
            with default output format, use -wide instead.
   -maxdump=n   dump only first n bytes of incoming data.
   -flat        no hexdump, print characters as they come.

  command chaining support

 since sfk 1.8.4 +hexdump uses text or binary input data
 from previous commands, but no filename lists:
   sfk xed in.dat +hexdump
     dumps chain data produced by xed
   sfk select mydir +hexdump
     dumps filename characters, but not file contents

 to read file contents use +hexfile instead:
   sfk select mydir .dat +hexfile
     dumps contents of files selected by a command

 sfk fhexdump  - same as hexfile
 sfk hexdumpb  - same as "sfk hexdump -nole" for binary
 sfk hexdumple - same as "sfk hexdump -showle" for text
 sfk postdump  - same as "sfk hexdump -post" for forums

  see also
 sfk hextobin  - convert hex dump back to original data.

web reference

 sfk hexdump in.dat
     dump contents of in.dat
 sfk hexdumple mydir .txt
     dump contents of all .txt files in mydir
     with highlight of (CR)LF line endings
 sfk sel mydir .txt +hexfilele -maxdump=128
     similar to above, first selecting files
     then dumping only first 128 bytes per file.
 sfk hexdump -offlen 4221566976 96 part1.avi
     dumps 96 bytes from offset 4221566976 within part1.avi
 sfk hexdump -offlen 0xFBA00000 0x60 part1.avi
     the same as above, but using hexadecimal numbers
 sfk echo foo +atow +hexdump -pure -off 2
     convert string to UCS2 wide chars, then
     dump this without the 2 bytes BOM header
 sfk postdump test.dat +toclip
     put test.dat contents into clipboard for posting
 sfk hexdump in.dat +view
     show hexdump in the depeche view text browser.
     works with files up to 4 mb with dview lite.
 sfk hexdump -pure -recsize=500 in.dat
     create a hexdump with 500 bytes per record.
 sfk hexfind in.dat -bin "/a1a2a3a4/"
     search byte sequence 0xa1a2a3a4 within in.dat
 sfk xhexfind in.dat "/\xa1\xa2\xa3\xa4/"
     same as above using xhexfind and simple expressions

   check if a script file contains just UNIX LF line endings,
   or DOS CR/LF format:

   sfk hexdump -showle thescript.bat

   >6364202E 2E0A726D 202D7266 20746D70< cd ...rm -rf tmp 00000000

   the result shows that the script is in UNIX format (just LF 0x0A,
   no CR/LF 0x0D0A).
