I wanted to share this very easy, quick and efficient way to concatenate several PDF files into a single file – this is a recapitulation of racin's post found at Matthew Skala's home page:
sudo apt-get install pdftk cd <folder containing your pdf's> pdftk *.pdf cat output all.pdf
That's all folks!
The actual process took ca. 1 second. Make sure you have named your files so that they are merged in the right order, e.g. 01_file-for-page-1.pdf, 02_file-for-page-2.pdf, etc.
I never use smilies, but there are exceptions that prove the rule
