如何获取 Mac OS 或 Windows 10 文件夹下所有 PDF 文件的字数

Question

I know some way to getting word count for a single PDF Files, but I have a folder which contains 500+ PDF files so I would like to know if there is a faster way to get the word count for all of them without opening every single file and do the copy past stuff like that.

I'm using macOS Catalina 10.15.5, If there is a solution for Windows 10 that also fine for me.

Answer 1

I just launched following command on my Windows machine:

Prompt>dir *.txt /S

There was an enormous output, and at the end, there was:

     Total Files Listed:
            3620 File(s)     93.074.638 bytes
               0 Dir(s)  410.585.006.080 bytes free

Edit after first comment
PDF is a format, which is made to be human-readable, not computer-readable, so doing some parsing and making some calculations on it, just using some simple computer commands, I don't believe it is even possible.

Answer 2

You can use pdfgrep which you can install with homebrew using:

brew install pdfgrep

Then your command to count the words in all the files will be:

pdfgrep -c -P  "\b.*\b"  *.pdf

Sample Output

Arduino Wireless Communication With the HC-12.pdf:512
sample.pdf:0
simple.pdf:4
text.pdf:22

The -P means to use PCRE , or "Perl Compatible Regular Expressions" wherein \b signifies a word boundary - ie the start or end of a word.
