[SOLVED] wanting to process v-card data

So, have you tried the file command on your dat file (the one that contains binary data)?

Not yet! I'm still "researching" while I

recover from knee surgery

The beauty of the *nix world is that your can learn about so much.

Tried the following:

Code:

prompt$  base64  <file1.png  >file1.b64
prompt$  base64 --decode  <file1.b64  >file1.dat
prompt$  file  file1.dat

file1.dat: PNG image data, 227 x 171, 8-bit/color RGB, non-interlaced

I also tried:

Code:

prompt$  base64  <file1.jpg  >file1.b64
prompt$  base64 --decode  <file1.b64  >file1.dat
prompt$  file  file1.dat

file1.dat: JPEG image data, JFIF standard 1.01

Clearly, there are bits in the decoded data that will inform 'file' about the
format of the original image.

So my utility needs to

extract the base64 blob
decode the base64 blob to a bit file
run the 'file' command against the bit file
grab the output of 'file' to learn the format
rename the bit file with the proper file type value

Thanks to all,
