将一个目前下面的文件，根据文件名前缀分散到不同的文件夹，比如 a12.jpg -> a/1/a12.jpg, b287.jpg -> b/2/b287.jpg 此方法用于处理由于最初设计上传文件夹没有分层次导致一个目录文件过多的问题。可以将一个目录下面的文件分散到子目录中
require "fileutils"
root_dir = "/Users/jason/Downloads/images"
Dir.chdir(root_dir)
puts Dir.pwd
Dir.glob("**/*.{jpg}").each do |fname|
tfname = fname.split("/").last
if fname.match("[small|large|normal]_")
tfname = fname.split("_").last
end
p1,p2 = tfname[0,1],tfname[1,1]

Xcode 编译的时候自动修改 App 的 Build 为 Git 的 commit 次数，同时根据不同的 Build 模式，给 build 号加特别的后缀
GIT=/usr/bin/git
INFO_PLIST=$BUILT_PRODUCTS_DIR/$WRAPPER_NAME/Contents/Info.plist
BUILD_SUFIX=""
if [ $CONFIGURATION == Debug ]
then
BUILD_SUFIX="D"
