你知道你目前的项目代码有多少行吗？有多少个文件吗？有多少个文件夹吗？。。。^o(∩∩)o…哈哈，这个很简单，一句shell就搞定了，效率还非常之高:
1,统计你项目的.rb 结尾的代码行数，去掉空格
find . -type f -name "*.rb" | xargs cat | grep -v ^$ | wc -l
当然你还可以添加去掉注释
2,统计项目文件所有行数，包括空行
find . -type f | xargs cat | wc -l
3，统计项目有多少个文件
find . -type f | wc -l
4，统计项目有多少个文件夹
find . -type d | wc -l
5，找出项目下.rb 结尾的文件行数最大的一个(由小到大排序)
find . -type f -name "*.rb" | xargs wc -l | sort -n
6，自由发挥
总之find 命令结合 xargs 很强大的说
这些都是基本的用法，例如上面想得到tar.gz 等压缩包的内容就难了，那么可以借助cloc(perl库)得到更详细的信息,各种文件类型的行数，注释，空行等等信息:
ubuntu 安装:
sudo apt-get install cloc
使用:
wxianfeng@ubuntu:/usr/local/system/projects/redmine_1_0_3$ cloc . 6455 text files. 3119 unique files. 1035 files ignored. http://cloc.sourceforge.net v 1.09 T=13.0 s (204.8 files/s, 25293.4 lines/s) ------------------------------------------------------------------------------- Language files blank comment code scale 3rd gen. equiv ------------------------------------------------------------------------------- Ruby 2076 33371 44800 178357 x 4.20 = 749099.40 YAML 197 1299 691 44512 x 0.90 = 40060.80 Javascript 105 1963 2111 12461 x 1.48 = 18442.28 Ruby HTML 241 716 29 4862 x 4.00 = 19448.00 CSS 22 366 102 1889 x 1.00 = 1889.00 HTML 15 120 3 627 x 1.90 = 1191.30 Perl 2 80 98 233 x 4.00 = 932.00 SQL 3 17 2 96 x 2.29 = 219.84 XML 1 0 0 9 x 1.90 = 17.10 ------------------------------------------------------------------------------- SUM: 2662 37932 47836 243046 x 3.42 = 831299.72 -------------------------------------------------------------------------------
另外 rails 中已经封装了一个rake 任务，用来统计的，瞧瞧:
wxianfeng@ubuntu:/usr/local/system/projects/wxianfeng_com$ rake stats (in /usr/local/system/projects/wxianfeng_com) +----------------------+-------+-------+---------+---------+-----+-------+ | Name | Lines | LOC | Classes | Methods | M/C | LOC/M | +----------------------+-------+-------+---------+---------+-----+-------+ | Controllers | 2422 | 1978 | 36 | 215 | 5 | 7 | | Helpers | 858 | 712 | 0 | 103 | 0 | 4 | | Models | 3360 | 2661 | 55 | 447 | 8 | 3 | | Libraries | 1203 | 884 | 30 | 143 | 4 | 4 | | APIs | 436 | 353 | 17 | 23 | 1 | 13 | | Functional tests | 16 | 12 | 2 | 0 | 0 | 0 | | Unit tests | 16 | 12 | 3 | 0 | 0 | 0 | | Model specs | 2094 | 1680 | 1 | 24 | 24 | 68 | | View specs | 249 | 200 | 0 | 12 | 0 | 14 | | Controller specs | 3507 | 2734 | 2 | 37 | 18 | 71 | | Helper specs | 53 | 39 | 0 | 0 | 0 | 0 | | Library specs | 15 | 11 | 0 | 0 | 0 | 0 | +----------------------+-------+-------+---------+---------+-----+-------+ | Total | 14229 | 11276 | 146 | 1004 | 6 | 9 | +----------------------+-------+-------+---------+---------+-----+-------+ Code LOC: 6588 Test LOC: 4688 Code to Test Ratio: 1:0.7
