[hylafax-users] faxing multiple documents using sendfax & STDIN

[Ross McKerchar <it@xxxxxxxxxxxx>]

Hello,

I have successfully setup a custom program that sends faxes by piping 
postscript (or pdf) into sendfax via STDIN, roughly equivalent to doing 
"cat test.ps | sendfax -d test@000 " in a bash shell.

However, I would like to be able to sendmail multiple seperate PS or PDF 
documents in this manner. I have naively tried simpling concatenating 
the two documents (i.e. "cat test1.ps test2.ps | sendfax -d test@000") 
but I unsuprisingly get an email telling me the job as failed - sendfax 
understandably gets confused after reading the 1st  '%%EOF' marker.

Is there any delimiter I can insert to allow sendfax to accept multiple 
documents via the standard input? I have tried quite hard to avoid 
writing temporary files to disk in my setup and it would be a shame to 
have to use them now. I had a quick scan of sendfax.c++ but didn't see 
anything obvious, although that is most likely attributed to my poor C++ 
skills.

For a bit of background, this is part of a wider setup I have spent a 
fair bit of time on which performs faxing of MS Office documents via an 
email gateway. Once I get it all setup I'll post a wee howto as I'm 
aware this is an often requested feature.

regards,
