   Hey Tony!   
      
    TL> Well, having the CRC32 implemented would make my script more   
    TL> universal.   
      
   From what I've read thus far I seriously doubt there is such a thing as   
   'universal' when it comes to crc32.  However I did find at least one workable   
   solution (c source) that I slightly modified so that the internal printf only   
   outputs the crc32 8 character hex (0-9,A-F) checksum.  At the moment it is   
   only used by my fidonet account as I am sure that is the only place it might   
   ever get used and that is debatable.  However not having a common file(s) we   
   can test this idea with is the current holdup.  Anyhow it is around 5   
   milliseconds faster then the bash printf of cksum and the output is 32 bit   
   hex.  Your milage will vary.   
      
    TL> I'd br hsppy to use the Perl option, if I could find it for   
    TL> Raspian.   
      
   Do you currently use Raspian for fidonet?  The c source, if it turns out to be   
   compatible with the accepted method, would probably be a better option.   
      
    TL> we have to work with the TIC specs here.   
      
   Says who?  ;-)   
      
   Life is good,   
   Maurice
