Python同步文件

最近在做python开发，研究了技术大牛写的脚本，在他的脚本上做了优化。优化脚本已在做过测试还是挺好用的，如果你觉得不错就直接拿到生产用吧。

先直接放代码出来：

---------------------------------------------------------------------------------------------------------

import re,shutil,os,sys,filecmp

diffFilesList = []

def commpare(dir1,dir2):

    cmpobs=filecmp.dircmp(dir1,dir2)

    dir1_only=cmpobs.left_only

    dir1_diff=cmpobs.diff_files

    [diffFilesList.append(os.path.join(os.path.abspath(dir1),a)) for a in dir1_diff]

    [diffFilesList.append(os.path.join(os.path.abspath(dir1),a)) for a in dir1_only]

    if len(cmpobs.common_dirs) > 0:

        for a in cmpobs.common_dirs:

            commpare(os.path.abspath(os.path.join(dir1,a)),os.path.abspath(os.path.join(dir2,a)))

    return diffFilesList

def main():

    if len(sys.argv) < 3:

        print "Plese use %s sourcedir backdir" % sys.argv[0]

        sys.exit()

    else:

        dir1=os.path.abspath(sys.argv[1])

        dir2=os.path.abspath(sys.argv[2])

    ifMakeDir = True

    while ifMakeDir:

        diffFilesList = []

        destinationFiles = []

        ifMakeDir=False

        sourceFiles=commpare(dir1,dir2)

        for a in sourceFiles:

            destinationFile=re.sub(dir1,dir2,a)

            destinationFiles.append(destinationFile)

            if os.path.isdir(a):

                if not os.path.exists(destinationFile):

                    os.makedirs(destinationFile)

                    print "Make dir %s" % destinationFile

                    ifMakeDir=True

    destinationFiles = []

    sourceFiles=[]

    sourceFiles=commpare(dir1,dir2)

    [ destinationFiles.append(re.sub(dir1,dir2,a)) for a in sourceFiles]

    for a,b in zip(sourceFiles,destinationFiles):

        if os.path.isfile(a):

            print "Copy file %s to %s" % (a,b)

            shutil.copyfile(a,b)

    #print sourceFiles,destinationFiles

if __name__ == '__main__':

    main()

简单说明下脚本：

    简单说明下脚本，脚本对源数据与目的数据做对比，有差异的文件做替换和新增，对目录做新增。但对于目的数据多余的目录和文件，脚本不错处理。希望使用脚本的人能根据自己的场景灵活运用。
