So I'm trying to loop over a bunch of PDF files, grab their character count and divide that by 5. So output should be something like this:

PDF1.pdf
400

PDF2.pdf
1000

Assuming PDF1.pdf has 2000 characters and PDF2.pdf has 5000 characters. This is what I'm currently doing:

for %%f in (*.pdf) do (
    echo %%~nf.pdf
    pdftotext %%~nf.pdf -enc UTF-8 - | wc -m
)

What I really seek help with, is grabbing the value from wc -m, divide that by 5 and echo it out.

I've tried various things such as SET /A total=(wc -m) / 5 but nothing really seems to work out.

for %%f in (*.pdf) do (
 echo %%~nf.pdf
 for /f %%c in ('pdftotext %%~nf.pdf -enc UTF-8 - ^| wc -m') do set /a words=%%c / 5
 call echo %%words%%
)

should do the trick. Single-quote the command yielding the word-count - note the caret to escape the pipe. Assign the required value to words and use the call echo trick to produce the result.

There are other possibilities...

With decimals...

 for /f %%c in ('pdftotext %%~nf.pdf -enc UTF-8 - ^| wc -m') do set /a words=%%c*2
 call echo %%words:~0,-1%%.%%words:~-1%%.

Multiply by 2=required value *10; show all-bar-last-char, dot, last-char.

  • Hell yeah! That did it. Any clue how I could get it out with decimals? Right now it rounds it down. – MortenMoulder Nov 24 '16 at 13:15
  • The decimals didn't really work. I got `14100.6.` when I should get about `29.1114` in this case. – MortenMoulder Nov 24 '16 at 13:35
  • Er, which case? What was `%%c` to display that? Batch is actually limited to integers. How do you get `29.1114` by dividing an integer by 5? It would mean that `wc` is returning 145.557 words. – Magoo Nov 24 '16 at 13:42
  • 145557 words sounds about right yeah. I tagged this post with bash as well, as I'm using Git Bash to run the commands, otherwise won't `pdftotext` and `wc` work – MortenMoulder Nov 24 '16 at 13:45
  • 145557 gave me 29111.4 using the method I've shown. What thousands/decimal separators are you using? – Magoo Nov 24 '16 at 13:49
  • Ahh dammit, I got it right now. Wrong folder and wrong files!! Sorry, man. Works great! Thanks a lot! – MortenMoulder Nov 24 '16 at 13:50
