Hi All,
Does anyone know how to get at the PDF version for a directory of PDF files. I need to list these out for an internal customer to comply with Documentum. I've tried the get-metainfo.ps1 that has been posted. Also checking get-method but don't see how I can get to it yet. Any ideas??
Thanks in advance for any help.

How do I find the version info? By right clicking on the 'file | properties' or by opening it in a pdf reader and then do 'file | properties? |

Shay/Hal,
Thanks for your responses.
I came up with the line below which worked OK.
dir Y:\*.pdf|select name, @{n="Version";e= {(gc $_ |select-string "%PDF-*").tostring().substring(5,3)}}|ft -auto |

What errors did you get? Should end up with something like this...
Name Version
---- -------
14-010-01.pdf 1.3
14-010-02.pdf 1.3
28-060-03.pdf 1.3
28-057-05.pdf 1.3 |

I only get the name coulmn, for the value I get this error:
Select-Object : You cannot call a method on a null-valued expression.
It works only if I change 'gc $_ ...' to gc '$_.fullname ...'
Plus, it takes ton of time to complete and I have only 6 files in the directory.
Check this project, see if can help: http://pdfsharp.com/PDFsharp/

Not sure why you had to use fullname an I didn't...
There's probably a more efficient way to do it but this got the customers request taken care of.
If I have to do this again I'll probably try to tweak performance.
Are your PDF files large. Since we're using get-content to extract the %PDF part of the file for version I think it makes since that if the files are large it wll take a while. I went through 1806 files in about 15-20 minutes but the files were averaging probably 500K. |

The PDF files I tested were ~5mb. |

I found that if you add the '-totalCount 1' to get-content (instead of reading the entire file) then the command perform much faster. Can you conform that it works on your PDF files:
dir Y:\*.pdf | select name, @{n="Version";e= {( cat $_.fullname -totalCount 1 | select-string "%PDF-*").line.substring(1)}} | ft -auto |

Thanks Shay. That's smokin fast now. I didn't catch that the %PDF was in the 1st line of the PDF files.
It was taking 15-20minutes before to get through the 1800+ files and now less than a minute:)
That's a good one-liner to keep around:)
Thanks again for your help. |
