The easiest way to split and merge pdf files in linux

I scanned some documents to .pdf format but, I wanted to email them all in one .pdf file.

The easiest way to split, merge or edit pdf files in linux is to use pdftk.

sudo apt-get install pdftk

or

sudo aptitude install pdftk

or

sudo yum install pdftk

depending on what flavour of linux you have.

pdftk is quite powerful but, here are a few examples.

Split a multi-page pdf into separate files:

pdftk largepdfile.pdf burst

results in a number files like 0001.pdf, 0002.pdf, etc.

Merge files into one PDF file:

pdftk *.pdf cat output largepdfile.pdf

or

pdftk file1.pdf file2.pdf file3.pdf cat output largepdfile.pdf
