直接wc -c卡死了。

不对。

参数不对。

102928
➜ src git:(master) find . -type f -exec cat {} + | wc -c
30604953 看起来像是，但是不确定是否真的是对的：
- 总行数：102928 ？
- 10万行？
- 总字符个数：30604953 ？
- 3000多万？个字符
➜ src git:(master) find . -type f -exec wc -l {} \; | awk '{total += $1} END {print total}'
102928
➜ src git:(master) find . -type f -exec wc -c {} \; | awk '{total += $1} END {print total}'
30604953 还是这个数。

17万字符？倒是很像。

去看了看：

12万个字符？
感觉比较像。
14881 ./appendix/reference.md
1.4万个字符
13928个非空字符
和上面的 14881 很像。
后来去看了看，感觉是：把空格，换行等内容，也算进去了。
【总结】
目前，暂时用：
find . -name '*.md' | xargs wc -m
可以统计出，每一个md的Markdown文件的字符character个数，并且给出总数。
关于wc的用法，详见：
