[问与答] 有没有比较好用的比较 pdf 文件的命令行工具?

发表于

本来找到一个 https://github.com/vslavik/diff-pdf

brew install diff-pdf
diff-pdf 1.pdf 2.pdf -v
page 0 has 16174 pixels that differ
page 0 differs
1 of 1 pages differ.

结果,这个工具只能在 macOS 上面正常运行,在 win 下面,diff-pdf 1.pdf 2.pdf -v 后,是没有输出的。这样我们就没有办法根据是否有 diff ,进行相应的处理了。而且,这个 git repo ,没有 issue 页面,没办法提交问题

大家有没有好用的命令行工具,可以用来比较 pdf 的。谢谢!
