how many pages will my text files print on?

numpages() { echo $(($(wc -l $* | sed -n 's/ total$//p')/60)); }
This gives a very rough estimate of how many pages your text files will print on. Assumes 60 lines per page, and does not take long lines into account.

  • 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."

What Others Think

This is a bit shorter, only using awk: numpages() { awk 'END{print int(NR/60)}' "$@"; } awk reads through the file, then has an END condition to print NR (number of records (lines)). It's tempting to add a "+1" to the end, though. If the files are less than 60 lines in total, both our commands print: 0 !
