pdftk is a nifty little tool kit for Adobe PDF documents that decrypt, encrypt, join, remove pages, uncompress, repair, burst, and rotate .pdf files. I use it simply to rotate documents by 90 or 180 degrees from time to time. It is available via yum:
~>
sudo yum install pdftk
Press 'y' when
prompted to install the programs and any additional dependencies. After it is installed, source your ~/.bashrc
file: ~>
source ~/.bashrc
You are now ready to use pdftk. If you
need help with the syntax, type: ~>
pdftk --help
Rotating an entire PDF
document to 180 degrees, for example, can be done with the following
command: ~>
pdftk [input].pdf cat 1-endS output [output].pdf
As an application to quickly
tweak PDF documents, I find it to be very useful.
