Am 01. Feb, 2017 schwätzte Nathan so: moin moin,
You mentioned grep, but did you try 'strings' ? Does that even exist any more?
Yeah, strings is useful, but in this case I specifically need to check the binary content, so strings pulling the text out for me doesn't solve the primary issue. strings was useful for testing. As cat -v and grep --text. Perhaps I should just throw the image through aalib :). ciao, der.hans

Each server should be generating a PDF that looks exactly the same as from all the other servers. The PDF generation includes sticking in a few timestamps and possibly some hostnames or other dynamic content. The dynamic content eliminates the option of just using checksums to verify the output file is the same from all of the web servers. Any suggestions on how I can write a command line check. Needing to install a script would be far less than ideal in this situation. Funnily enough, needing to install a package would be less of an issue in this particular case, especially something in CentOS 6. Me being me, I did try to just grep out the lines with timestamps :). That didn't quite work :(. That probably indicates the files aren't as exactly the same as I hope. I didn't see a pdf2sanity tool. pdf2text won't really work as I need to verify the graphic content and hopefully the PDF wrapper. ciao, der.hans
