Linux 统计代码行数的代码

统计文件行数（单个文件）：

wc -l file

例如：
homer@ubuntu:~/workspace/android/game$ wc -l lgameandroid2dactivity.java
906 lgameandroid2dactivity.java

统计目录所有文件行数（全部目录）：

find . -name *.java | xargs wc -l

例如：

homer@ubuntu:~/workspace/android$ find . -name *.java | xargs wc -l
    817 ./game/core/lhandler.java
    140 ./game/core/lflicker.java
    ...
    515 ./game/utils/collection/arraymap.java
    162 ./game/utils/collisionutils.java
    178 ./game/utils/numberutils.java
  68753 total

统计目录并按行数排序（按行大小排序）：

 find . -name *.java | xargs wc -l | sort -n

homer@ubuntu:~/workspace/android$ find . -name *.java | xargs wc -l | sort -n
     25 ./game/action/sprite/collidable.java
     26 ./game/core/graphics/component/collisionquery.java
     27 ./game/core/graphics/filter/imagefilter.java
     28 ./game/lmode.java
     ...
   1467 ./game/core/geom/path2d.java
   1919 ./game/core/graphics/screen.java
   2417 ./game/core/graphics/device/lgraphics.java
   3050 ./game/core/geom/affinetransform.java
  68753 total

统计目录并按行数排序（按行文件名排序）：

find . -name *.java | xargs wc -l | sort -k2

homer@ubuntu:~/workspace/android$ find . -name *.java | xargs wc -l | sort -k2
    210 ./game/action/actioncontrol.java
    116 ./game/action/actionevent.java
     34 ./game/action/actionlistener.java
     ....
    178 ./game/utils/numberutils.java
    342 ./game/utils/recordstoreutils.java
     58 ./game/utils/screenutils.java
    650 ./game/utils/stringutils.java
