I am trying to write a script to delete the files with a particular name on the FTP server. I dont want to delete all the files with *.txt extension. The file name would be like


I am trying to do something like this.

cd FolderName
mdelete *.txt --- here I want to pass a wild card to delete only files with a particular name and not all files with a .txt extension

This will be a unattended batch script scheduled to run everyday. I am not very familiar with the programming languages. Please provide a simple solution if possible. Thanks

* are only valid at the end of the string with mdelete.

So then what would be needed to be done to achieve my goal?

If there are no files with extensions other than txt for the pattern you want, you might be able to do something like:

mdelete 20110915_*.*

wait you say you want to delete all files EXCEPT the ones with .txt extenstion?

if so lets say the "name" you mention above is potato then it would be

mdelete potato*

There are files with extensions other than txt. I want to add the wild card of the filename

eg mdelete filename_*.txt

The pattern for the file is DATE_FileName.txt
 eg: 20110915_Myfile.txt

I want to add "Myfile" as the wildcard
The date part will change everyday and the rest of the filename would be the same.

There are other files with the extension of txt and with other extensions.

Thanks for the help. I appreciate it.

You could do this with a Robo-FTP script configured to run as a Windows Service.  This way the operating system will automatically restart the job whever the computer reboots.

This example script will delete all the files named with your date-based wildcard pattern calculated using the date 3 days ago.  It is designed to execute immediately the first time you run it and then at 10pm every night after that:
;; Find the date 3 days ago
SET myDate = %date 
DATESUB yesterday 3      

;; Parse date as string with "-" character as delimiter
;; then rearrange the values to change the name pattern 
SETEXTRACT month = yesterday "-" 1
SETEXTRACT day = yesterday "-" 2
SETEXTRACT year = yesterday "-" 3
SET MyWildcard = "20" + year + month + day + "*.txt"

;; delete all files that match name wildcard pattern
FTPLOGON "" /user="UserID" /pw="Secret"
FTPCD "/subfolder"

;; wait until 10pm
PAUSE /until=22:00
GOTO start

Open in new window

Of course you'll need to modify the login information on line 14 and the name of the remote site's subfolder on line 15 but otherwise it should be good to go.  It is a modified version of this:

The only way to reliably perform that via (standard) FTP is to get the directory listing, filter the files you want to delete, and generate delete commands for each file name.

Qlemo is correct.  If you look at the protocol trace log this is exactly how the Robo-FTP script I posted above does it't work.

If you can connect via SFTP, then the open source PuTTY client includes PSFTP, and it does support delete commands like:

del foo*.txt

Like Robo-FTP, not free, but another FTP scripting tool that does support wildcard deletes.

I just did
mdelete *pattern*.* and it delete all the files containing the "pattern"
I did not think it would be that straightforward.

Thanks experts for all your comments. I appreciate the help.,
