- | ===== [[checking_file_existence]] Checking file existence ===== | ||
- | |||
- | &deprecated_use_net | ||
- | |||
- | You may use following [[guide_automation_advanced#wsh|Windows script host JavaScript code]] (''example.js''): | ||
- | |||
- | <code javascript> | ||
- | // Configuration | ||
- | |||
- | // Remote file search for | ||
- | var FILEPATH = "/home/user/myfile.dat"; | ||
- | // Session to connect to | ||
- | var SESSION = "session"; | ||
- | // Path to winscp.com | ||
- | var WINSCP = "c:\\program files\\winscp\\winscp.com"; | ||
- | |||
- | var filesys = WScript.CreateObject("Scripting.FileSystemObject"); | ||
- | var shell = WScript.CreateObject("WScript.Shell"); | ||
- | |||
- | var logfilepath = filesys.GetSpecialFolder(2) + "\\" + filesys.GetTempName() + ".xml"; | ||
- | |||
- | var p = FILEPATH.lastIndexOf('/'); | ||
- | var path = FILEPATH.substring(0, p); | ||
- | var filename = FILEPATH.substring(p + 1); | ||
- | |||
- | var exec; | ||
- | |||
- | // run winscp to check for file existence | ||
- | exec = shell.Exec("\"" + WINSCP + "\" /log=\"" + logfilepath + "\""); | ||
- | exec.StdIn.Write( | ||
- | "option batch abort\n" + | ||
- | "open \"" + SESSION + "\"\n" + | ||
- | "ls \"" + path + "\"\n" + | ||
- | "exit\n"); | ||
- | |||
- | // wait until the script finishes | ||
- | while (exec.Status == 0) | ||
- | { | ||
- | WScript.Sleep(100); | ||
- | WScript.Echo(exec.StdOut.ReadAll()); | ||
- | } | ||
- | |||
- | if (exec.ExitCode != 0) | ||
- | { | ||
- | WScript.Echo("Error checking for file existence"); | ||
- | WScript.Quit(1); | ||
- | } | ||
- | |||
- | // look for log file | ||
- | var logfile = filesys.GetFile(logfilepath); | ||
- | |||
- | if (logfile == null) | ||
- | { | ||
- | WScript.Echo("Cannot find log file"); | ||
- | WScript.Quit(1); | ||
- | } | ||
- | |||
- | // parse XML log file | ||
- | var doc = new ActiveXObject("MSXML2.DOMDocument"); | ||
- | doc.async = false; | ||
- | doc.load(logfilepath); | ||
- | |||
- | doc.setProperty("SelectionNamespaces", | ||
- | "xmlns:w='http://winscp.net/schema/session/1.0'"); | ||
- | |||
- | var nodes = doc.selectNodes("//w:file/w:filename[@value='" + filename + "']"); | ||
- | |||
- | if (nodes.length > 0) | ||
- | { | ||
- | WScript.Echo("File found"); | ||
- | // signalize file existence to calling process; | ||
- | // you can also continue with processing (e.g. downloading the file) | ||
- | // directly from the script here | ||
- | WScript.Quit(0); | ||
- | } | ||
- | else | ||
- | { | ||
- | WScript.Echo("File not found"); | ||
- | WScript.Quit(1); | ||
- | } | ||
- | </code> | ||
- | |||
- | Run the script with command: | ||
- | <code> | ||
- | cscript /nologo example.js | ||
- | </code> | ||
- | |||
- | Following batch file shown how to continue with processing based on file exitence: | ||
- | <code> | ||
- | cscript /nologo example.js | ||
- | if errorlevel 1 goto error | ||
- | |||
- | echo File exists, do something | ||
- | rem Do something | ||
- | exit | ||
- | |||
- | :error | ||
- | echo Error or file not exists | ||
- | </code> | ||
- | |||
- | Alternatively you can continue with the processing directly in JavaScript code as suggested by respective comments. | ||
- | |||
- | ===== [[local_move_after_successful_upload]] Moving local files to different location after successful upload ===== | ||
- | &deprecated_use_net | ||
- | |||
- | WinSCP does not support move command for local files. Instead you can combine WinSCP script with batch file: | ||
- | |||
- | <code winscp> | ||
- | option batch abort | ||
- | option confirm off | ||
- | # Connect | ||
- | open mysession | ||
- | # Upload the files | ||
- | put *.* | ||
- | </code> | ||
- | |||
- | Launch the above script from batch file like the one below: | ||
- | |||
- | <code> | ||
- | winscp.com /script=example.txt | ||
- | if errorlevel 1 goto error | ||
- | |||
- | echo Upload succeeded, moving local files | ||
- | move *.* c:\backup\ | ||
- | exit | ||
- | |||
- | :error | ||
- | echo Upload failed, keeping local files | ||
- | </code> | ||
- | |||
- | ===== [[synchronize_any_local_file]] Shortcut to synchronize any local directory with remote directory ===== | ||
- | |||
- | You may want to have a script that synchronizes any local directory with a same-named subdirectory of fixed remote path, e.g.: | ||
- | * ''c:\www\gallery'' with ''/home/user/www/gallery''; | ||
- | * ''c:\documents and settings\username\www\forum'' with ''/home/user/www/forum''. | ||
- | |||
- | Such a script is particularly useful for integrating with Windows Explorer's 'Send To' menu. | ||
- | |||
- | First create wrapper batch file to store the paths you want to synchronize into environment variables (change ''/home/user/www/'' to remote path root you want to synchronize against): | ||
- | <code> | ||
- | winscp.com /script=example.txt /parameter %1 "/home/user/www/%~n1%~x1" | ||
- | </code> | ||
- | |||
- | The script ''example.txt'' may look like: | ||
- | |||
- | <code winscp> | ||
- | # Being intended for interactive session, we are not enabling batch mode | ||
- | # Connect | ||
- | open mysession | ||
- | # Synchronize paths provided via environment variables | ||
- | synchronize remote "%1%" "%2%" | ||
- | </code> | ||
- | |||
- | Then you can make a shortcut to the batch file: | ||
- | * When placed on desktop, you can drop any local directory to it to start synchronization; | ||
- | * When placed to ''c:\documents and settings\username\sendto'', you can use //Send To > Your Shortcut// from context menu of any local directory. | ||
- | |||
- | ===== [[auto_compress_download]] Automatically compress files before download ===== | ||
- | Following script compresses selected files into tar/gzip archive and downloads it: | ||
- | |||
- | <code winscp> | ||
- | option batch abort | ||
- | option confirm off | ||
- | open mysession | ||
- | cd %1% | ||
- | call tar -czf /tmp/archive.tar.gz %2% | ||
- | lpwd | ||
- | get -delete /tmp/archive.tar.gz | ||
- | exit | ||
- | </code> | ||
- | |||
- | Launch the above script from batch file like the one below, which automatically decompresses the archive: | ||
- | |||
- | <code> | ||
- | winscp.com /script=example.txt /parameter %* | ||
- | if errorlevel 1 goto error | ||
- | |||
- | echo Retrieving files succeeded | ||
- | gzip -d archive.tar.gz | ||
- | tar -xf archive.tar | ||
- | del archive.tar | ||
- | exit | ||
- | |||
- | :error | ||
- | echo Retrieving files failed | ||
- | </code> | ||
- | |||
- | Example of running the batch file to download all files under ''/home/user/www'': | ||
- | |||
- | <code> | ||
- | example.bat /home/user/www *.* | ||
- | </code> | ||
- | |||
- | The batch file needs Windows ports of ''gzip'' and ''tar'' tools. You can get them from [[http://sourceforge.net/projects/unxutils/|UnxUtils]] project. | ||
