I have do download all log files from a virtual directory within a site. The access to virtual directory is forbidden but files are accessible.
I have manually entered the file names to download
dir="Mar"
for ((i=1;i<100;i++)); do
wget http://sz.dsyn.com/2014/$dir/log_$i.txt
done
The problem is the script is not generic and most of the time I need to find out how many files are there and tweak the for loop. Is there a way to trigger wget to fetch all files without me bothering to specify the exact count.
Note:
If I use the browser to view http://sz.dsyn.com/2014/$dir, it is 403 forbidden. I cant pull all the files via browser tool/extension.
First of all check this similar question If this is not what you are looking for, you need to generate a file of URLs within and feed wget. e.g.
wget --input-file=http://sz.dsyn.com/2014/$dir/filelist.txt
wget will have the same problem your browser has: it cannot read the directory. Just pull until your first failure then quit.

I am transferring files through PSFTP to 3rd party server using Batch files. While transferring files, due to buffering issues, files are being broken/not transferred fully.
As a remedy, 3rd party requested us to name each file with '.new' before starting file transfer and remove '.new' once file is transferred fully/successfully.
Please let me know Batch script commands to implement above. Please let me know if you need additional info.
To rename a file, use mv command (or it's ren alias):
put c:\local\path\file /remote/path/file.new
mv /remote/path/file.new /remote/path/file
Though if you are transferring multiple files using a wildcard, this won't help you.
A relatively simple solution for multiple files is using a temporary upload folder. After the upload finishes, you can move all files at once to the target folder:
mput c:\local\path\* /temp/path
mv /temp/path/* /remote/path
For a similar discussion, see also SFTP file lock mechanism.
If you need to use the solution with extensions, you can use WinSCP, as it allows you to automatically use a temporary file name for upload. Though it uses .filepart, not .new extension.
put -resumesupport=on c:\local\path\* /remote/path/
See WinSCP article on Uploading to temporary file name for more details.
The article also shows (a way more complicated) solution using WinSCP .NET assembly that allows you to use even the .new extension.
If you choose to switch to WinSCP, there's a guide for converting psftp script to WinSCP.

There are multiple folders with subfolders and image files on the FTP server. The -R is disabled. I need to dump the recursive directory listing with the path name in a text file. The logic I have till now is that, traverse in each folder, check the folder name if it consists of '.' to verify it as a file or a folder, if its a folder, go in and check for subfolders or files and list them. Since I cannot go with the -R, I have to go with a function to perform traverse each folder.
#!/bin/sh
ftp_host='1.1.1.1'
userName='uName'
ftp -in <<EOF
open $ftp_host
user $userName
recurList() {
path=`pwd`
level=()
for entry in `ls`
do
`cwd`
close
bye
EOF
I am stuck with the argument for the for loop!
Sorry to see you didn't get any replies yet. I think the reason may be that Bash isn't a good way to solve this problem, since it requires interacting with the FTP client, i.e. sending commands and reading responses. Bash is no good at that sort of thing. So there is no easy answer other than "don't use Bash".
I suggest you look at two other tools.
Firstly, you may be able to get the information you want using http://curlftpfs.sourceforge.net/. If you mount the FTP server using curlftpfs, then you can use the find command to dump the directory structure. This is the easiest option... if it works!
Alternatively, you could write a program using Python with the ftplib module: https://docs.python.org/2/library/ftplib.html. The module allows you to interact with the FTP server through API calls.
Dropbox makes it easy to programmatically download a single file via curl (EX: curl -O https://dl.dropboxusercontent.com/s/file.ext). It is a little bit trickier for a folder (regular directory folder, not zipped). The shared link for a folder, as opposed to a file, does not link directly to the zipped folder (Dropbox automatically zips the folder before it is downloaded). It would appear that you could just add ?dl=1 to the end of the link, as this will directly start the download in a browser. This, however, points to an intermediary html document that redirects to the actual zip folder and does not seem to work with curl. Is there anyway to use curl to download a folder via a shared link? I realize that the best solution would be to use the Dropbox api, but for this project it is important to keep it as simple as possible. Additionally, the solution must be incorporated into a bash shell script.
It does appear to be possible with curl by using the -L option. This forces curl to follow the redirect. Additionally, it is important to specify an output name with a .zip extension, as the default will be a random alpha-numeric name with no extension. Finally, do not forget to add the ?dl=1 to the end of the link. Without it, curl will never reach the redirect page.
curl -L -o newName.zip https://www.dropbox.com/sh/[folderLink]?dl=1
Follow redirects (use -L). Your immediate problem is that Curl is not following redirects.
Set a filename. (Optional)
Dropbox already sends a Content-Disposition Header with its Dropbox filename. There is no reason to specify the filename if you use the correct curl flags.
Conversely, you can force a filename using something of your choosing.
Use one of these commands:
curl https://www.dropbox.com/sh/AAbbCCEeFF123?dl=1 -O -J -L
Preserve/write the remote filename (-O,-J) and follows any redirects (-L).
This same line works for both individually shared files or entire folders.
Folders will save as a .zip automatically (based on folder name).
Don't forget to change the parameter ?dl=0 to ?dl=1 (see comments).
OR:
curl https://www.dropbox.com/sh/AAbbCCEeFF123?dl=1 -L -o [filename]
Follow any redirects (-L) and set a filename (-o) of your choosing.
NOTE: Using the -J flag in general:
WARNING: Exercise judicious use of this option, especially on Windows. A rogue server could send you the name of a DLL or other file that could possibly be loaded automatically by Windows or some third party software.
Please consult: https://curl.haxx.se/docs/manpage.html#OPTIONS (See: -O, -J, -L, -o) for more.
I'm trying to find a way to see if a file exists on an ftp site via DOS. I tried a get command on the file hoping that if it didn't exist it wouldn't download it to my local directory. However it seams that it still does, but it's an empty file. This doesn't work for me however because the file I'm looking for is just a empty trigger file so I can't tell the difference.
I would like to dump a listing ls of the ftp directory to a text file on my local drive and so I try
ls > listing.txt.
It creates the listing.txt file locally but it's always empty even though there are files on the ftp site.
What are my options with this?
I have used dir > listing.txt and ls > listing.txt and every time listing.txt is empty even though there are files in the directories I'm running those commands on.
Sorry if I didn't make this clear, but I'm trying to get the listing for an automated process and not simply for my visual when manually doing this.
Unless you're on FreeDOS, you're probably not using DOS. Perhaps you're using ftp.exe in the windows console? If that's the case, don't use a normal file redirect. Instead check here the syntax for ls in the standard Windows ftp client:
ls [RemoteDirectory] [LocalFile]
So you can do a ls . listing.txt to get a list of files in the current remote directory. The listing.txt file will appear in your user directory, e.g. c:\Users\user.
I am attempting to create a dynamic list of files available in an ftp directory. I assume wget can help with this but I'm not really sure how...so my question is:
What is the syntax for retrieving file names from an ftp directory using wget?
Just execute
wget --no-remove-listing ftp://myftpserver/ftpdirectory/
This will generate two files: .listing (this is what you are looking for) and index.html which is the html version of the listing file.
