Python Synchronization files

Recently in Python development, I studied the script written by the technology Daniel and optimized it in his script. Optimization scripts have been tested or very useful, if you think it is good to directly get production use it.

Put the code directly first:

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

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 ()

Look directly at the effect:

8 Directories, 6 files

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

A simple description of the script:

Simple instructions under the script, the script to the source data and the destination data to do the comparison, there are different files to replace and add to the directory to do new. But for the destination data redundant directories and files, the script good processing. People who want to use scripts can be used flexibly based on their own scenarios.

Just started to write a blog, write more hasty, follow-up will share more vivid articles!
