  • Rearrange pdf document coming from a simplex document feed scanner, feeded first with odd pages, then with even pages from the end. Needs pdftk >1.44 w/ shuffle. Similar to http://www.commandlinefu.com/commands/view/7965/pdf-simplex-to-duplex-merge where there are 2 separate documents, odd and even

  • Useful if you don't have at hand the ability to automatically create a booklet, but still want to. F is the number of pages to print. It *must* be a multiple of 4; append extra blank pages if needed. In evince, these are the steps to print it, adapted from https://help.gnome.org/users/evince/stable/duplex-npage.html.en : 1) Click File ▸ Print. 2) Choose the General tab. Under Range, choose Pages. Type the numbers of the pages in this order (this is what this one-liner does for you): n, 1, 2, n-1, n-2, 3, 4, n-3, n-4, 5, 6, n-5, n-6, 7, 8, n-7, n-8, 9, 10, n-9, n-10, 11, 12, n-11... ...until you have typed n-number of pages. 3) Choose the Page Setup tab. - Assuming a duplex printer: Under Layout, in the Two-side menu, select Short Edge (Flip). - If you can only print on one side, you have to print twice, one for the odd pages and one for the even pages. In the Pages per side option, select 2. In the Page ordering menu, select Left to right. 4) Click Print. Show Sample Output

    F=136; [[ $(($F % 4)) == 0 ]] && for i in $(seq 1 $(($F/4))); do echo -n $(($F-2*($i-1))),$((2*$i-1)),$((2*$i)),$(($F-2*$i+1)),; done | sed 's/,$/\n/' || echo "Make F a multiple of 4."

  • The pinfo package makes info pages much more bearable. It is a ncurses-based POSIX utility for viewing info and man pages using lynx style keyboard shortcuts and rendering. Links are highlighted blue, the current location of your cursor is red. Navigating and searching are easy. Worth the install.
