This script want to download every day (at night) xsceneries of the fgfs ftp server. Like in my case with my isp, 10 MB downloadedat night is counted as 5 MB.Define the different variables before executing this script! Otherwise itprobably not work. Place this script as an cron job task and give it the job toexecute it every 2 days for example. Similar is possible with the 'tasks' onMicrosoft Windows. Version: 0.1############ TODO: ############- Finish this script!- Almost done, need to test -> Get an content list of the ftp server to download.- Find another way, without using wget, with ftplib probably.##"""###### Defining the different variables## Numbers of download at a day(night)number_downloads = 1# Path of the sceneries downloaded#download_dir = "./downloaded/"download_dir = "/mnt/backup/fgfs_stuff/additional_sceneries/"# Utility to download the sceneriesdownloader_tool = "/usr/bin/wget --directory-prefix=%s" % (download_dir)# The FTP server addrftpserver_download_path = "ftp.flightgear.org"# The dir on the FTP serverftpserver_path_dir = "/pub/fgfs/Scenery-0.9.10"# Concatenated server download path (for downloading with wget)server_download_path = "ftp://" + ftpserver_download_path + ftpserver_path_dir# File with info of the sceneries to download#fgfs_sceneries = "./to_download.txt"fgfs_sceneries = "/home/david/Docs/fgfs_docs/sceneries_downloader/to_download.txt"# File with info of the sceneries already download#already_downloaded_file = "./already_downloaded.txt"already_downloaded_file = "/home/david/Docs/fgfs_docs/sceneries_downloader/already_downloaded.txt"# Countercounter = 0######"""If the download list text file not exist, get the content of the ftp'server_download_path' and put it in an txt file.Actually an list of files are already done manually but need somethings better,for when there an new fgfs version."""###if not download_list#ftp geek manual command :-) Need to automatisate it!# Then remove these not needed colums#cat filename | awk '{ print $9 }' > newfile"""# Try:# file(fgfs_sceneries, "r")#if(ExceptErro: = file not found)# do next oneftp = FTP(ftpserver_download_path)# Identify to the ftp server default, i.e : user anonymous, passwd anonymous@ftp.login()# Change the current directoryftp.cwd(ftpserver_path_dir)# Get the content of the ftp dir an put it in an varftpfiles = ftp.nlst()ftp.close()# Append each item to an text file ('fgfs_sceneries')for item in ftpfiles: write_newfile = file(fgfs_sceneries, "a") write_newfile.write('\n' + item.rstrip()) write_newfile.close()"""# Else the download list existe### print "The download list detected""""Read an item of the 'fgfs_sceneries' file first open the file to read(r)If to_download file is empty, probably nothings more to download"""to_download = file(fgfs_sceneries, "r")# If to_download file is empty, probably nothings more to download# Read the file into a list then print it# when counter are egual to x stop itfor item in to_download: if(counter < number_downloads): counter += 1 # Increment counter by one print "Ready to download item %s file %s" % (counter, item) # Download the item # With wget (probably to remove wiht wget!) #os.popen("%s %s/%s" % (downloader_tool, server_download_path, item)) # Do it with ftplib! ftp = FTP(ftpserver_download_path) ftp.login() # Change the current directory ftp.cwd(ftpserver_path_dir) # Get the item ftp.retrbinary('RETR %s' % item, open('%s' % item, 'wb').write) ftp.close() # Once downloaded add the item of $fgfs_sceneries to $already_download write_already_downloaded_file = file(already_downloaded_file, "a") write_already_downloaded_file.write('\n' + line.rstrip()) write_already_downloaded_file.close() # Remove the downloaded item of $fgfs_sceneries fp = open(fgfs_sceneries, "r") lines = fp.readlines() fp.close() del lines[0] # Delete firt line fp = open(fgfs_sceneries, "w") fp.writelines(lines) fp.close() ## print "Downloaded item %s done" % (line.rstrip()) # rstrip to remove \n after 'line'# Close the opened fileto_download.close()
