You can just use

You could try something like:
你可以尝试这样的事情：
find . -name "*.java" -exec cat {} \; | wc -l
回答by Malvolio
My suggestions would be
我的建议是
- Use a
findcommand as in Barti's answer to locate all the files - Use
sedor something to strip out all the comments - Don't do it at all
- 使用
findBarti's answer 中的命令来定位所有文件 - 使用
sed或某物去除所有评论 - 根本不要这样做
SLOC is a very, very misleading way to measure software. Bill Gates said it was like estimating the quality of an aircraft by weight, and it may be the only helpful thing he ever said.
SLOC 是一种非常非常具有误导性的衡量软件的方法。比尔盖茨说这就像用重量来估计一架飞机的质量，这可能是他说过的唯一有用的话。

Already been answered, just giving another way using awkwhich you'll definitely have.
已经回答了，只是提供另一种awk你肯定会使用的方法。
cat *.ext | awk 'BEGIN{i=0;} {i++;} END{print "Lines ", i}'
cat *.ext | awk 'BEGIN{i=0;} {i++;} END{print "Lines ", i}'
I only also suggest this because it can be easily edited to add patterns (such as comments) for lines that you don't want to count.
我也只是建议这样做，因为它可以很容易地编辑为您不想计算的行添加模式（例如注释）。

This will count empty lines as well, but it's easy. Go to the specific directory you wanna check and do
这也将计算空行，但这很容易。转到您要检查并执行的特定目录
find . | wc
