Check for psftp file upload error in batch file - batch-file

I am trying to upload a file from Windows server to third party server (I do not know OS etc. of this) through windows batch script. I am using PSFTP to upload files. It was working since a long time but since yesterday while uploading files, I am getting 'Network error: connection timed out' and batch script file control is doing further steps after file uploading step.
My requirement is whenever there is a failure to upload a file through psftp command through batch script, system should not proceed further. It should stop executing further steps.
Please let me know how to do this in Windows batch scripting?

psftp returns exit code 1 on error. So you just check the exit code and act accordingly.
To records errors, just redirect all psftp.exe output to a file.
psftp.exe -b script.txt > script.log 2>&1
if errorlevel 1 (
echo Error
) else (
echo Success
rem Other commands to perform on success
)

Using 'for' command to find and download the latest file on SFTP server in PSFTP

I have gone through the following guide to set up an SSIS package to retrieve a text file located on an SFTP server:
https://www.mssqltips.com/sqlservertip/3435/using-sftp-with-sql-server-integration-services/
To summarize, the SSIS package executes PSFTP.exe (A PuTTY tool) which takes the necessary credentials to connect to the server. It also takes a batch file that it executes after connecting. This batch file contains the commands to retrieve the desired text file. To start from the guide, it simply contains a cmd command to change directory, and a get command to retrieve the file:
cmd DataDump
get TeleMarketingResults.txt
All of this works fine.
The issue arises when I try to make this batch file logic more complex as it does not seem to recognize basic keywords. For instance, I would like to modify it to retrieve the most recent file, so I tried adding this:
for /f %%i in ('dir /b/a-d/od/t:c') do set LAST=%%i
echo The most recently created file is %LAST%
but then I get these errors:
psftp: unknown command "for"
psftp: unknown command "echo"
If I execute the batch file manually in a local directory, it works. The issue only occurs when passing it as a parameter to PSFTP.exe. Why is this?
psftp script file can contain psftp commands only. for, set or dir are not psftp commands.
There's hardly any reasonable way to retrieve latest file using psftp. You would have to do it in two steps. First to retrieve listing and store it to a file. Then parse that file using some smart batch file commands to find the latest files. And then run psftp again to download that file. It is cumbersome and ineffective as it requires two connections.
You better use a more powerful SFTP client. For example it's trivial with my WinSCP SFTP client. See
Question WinSCP select most recent file or
WinSCP article Downloading the most recent file.

Ignore Error Code 2 PSFTP

We have an desktop application that dynamically generates a command file to pull specific files that have the current date in the name. So in the end we have a command file that looks like this:
lcd e:\localpath
mget Filename0111.dat
mget Filenametwo0111.dat
mget Filenamethree0111.dat
bye
Where 0111 is MMDD. The command file is created via a .bat file that the desktop app executes. The application then connects to the remote server via PSFTP.exe and runs that command file to pull files.
The problem we're running into is we updated the PSFTP.exe to a newer version due to a separate issue that occurred. Now if a file is not available on the remote server it returns an error code 2 which stops the rest of the files from being retrieved. So if the first file in the list doesn't exist then it fails and the rest of the files are not downloaded.
Is there a way to ignore the error code 2 so that the rest of the files get retrieved? I had thought at first to run PSFTP.exe and it's commands through a batch file but that didn't work.
Any ideas?
PSFTP.exe has a command -be that will continue executing the batch if there is an issue.
When running a batch file, this option causes PSFTP to continue processing even if a command fails to complete successfully.
You might want this to happen if you wanted to delete a file and didn't care if it was already not present, for example.

WinSCP - Doing post-processing in a BAT file

Here's what I want to do using WinSCP called from a BAT file:
Execute a WinSCP script that uploads files to an FTP site.
Test the success of the upload.
If successful, move the files on the local machine to another folder.
If unsuccessful, do nothing.
I have tried the example batch file shown at the WinSCP site, but after the WinSCP command is executing, the remainder of the bat file is ignored.
See:
https://winscp.net/eng/docs/script_local_move_after_successful_upload
The official example was missing exit command at the end of the WinSCP script.
It should be:
# Connect
open mysession
# Upload the files
put *.*
# Exit WinSCP
exit
Then the batch file will correctly process the other commands:
winscp.com /script=example.txt
if %ERRORLEVEL% neq 0 goto error
echo Upload succeeded, moving local files
move *.* c:\backup\
exit 0
:error
echo Upload failed, keeping local files
exit 1
I have corrected the example.

SQL Server agent for scheduling SFTP using WinSCP under SSIS

I have a batch script which generates a WinSCP upload script to upload a file to an SFTP location. Now when I run the batch file via command prompt - it runs successfully and loads it. I called the same thru SSIS Execute process task - it runs successfully and loads it. Now when I put the same on SQL Agent - I tried the following two options:
Using Operating System (CmdExec) - cmd.exe /c "\.bat"
Added the SSIS package to SSISDB and added it as a job step.
With both the above options the job showed a successful run. However the file is not uploaded! Any ideas on what is happening?
Here's my batch script:
echo off
SET winscp=C:\"Program Files (x86)"\WinSCP\WinSCP.com
SET stagingDirectory=\\<staging path>\
SET scriptPath=\\<ScriptPath>\UploadScript.txt
SET ftpHost=xx.xx.xx.xx
SET ftpUser=user
SET ftpPass=password
SET fileName=Test.xlsx
SET ftpFlags=
#REM ftpFlags: -explicit
echo deleting uploadScript if it already exists
IF EXIST %scriptPath% del /F %scriptPath%
IF EXIST %scriptPath% exit 1
echo Generating WINSCP Upload Script
>>%scriptPath% echo option batch abort
>>%scriptPath% echo option confirm off
>>%scriptPath% echo open sftp://%ftpUser%:%ftpPass%#%ftpHost% %ftpFlags%
>>%scriptPath% echo option transfer binary
>>%scriptPath% echo put %stagingDirectory%%fileName% /
>>%scriptPath% echo close
>>%scriptPath% echo exit
echo Launching WINSCP upload
start /wait %winscp% /console /script=%scriptPath%
As you start the WinSCP via the start (why?), the exit code is not propagated to the SSIS. So, you never learn, if the script fails. And it most probably fails.
You also should enable logging, so that you can see what's wrong.
You should use this code to propagate the WinSCP exit code to SSIS and to enable logging:
%winscp% /log=\\<ScriptPath>\UploadScript.log /script=%scriptPath%
exit /b %ERRORLEVEL%
(Note that the winscp.com does not have the /console parameter)
Anyway, one clear problem is that you do not specify an expected SSH host key in the script. When you run the script manually, you probably have the key cached in the registry of your Windows account. But under the SSIS a different account is used, and its host key cache is likely empty. You should add the -hostkey switch to the open command in the script to make the script independent on the cache. See Where do I get SSH host key fingerprint to authorize the server?
When testing the script, add the /ini=nul parameter to isolate the script from your configuration.
For this and other hints, when debugging WinSCP running under SSIS, see My script works fine when executed manually, but fails or hangs when run by Windows Scheduler, SSIS or other automation service. What am I doing wrong?
And finally, see WinSCP SFTP Task for SSIS.
Your variable seems set incorrectly. To manage with a space in the path and into the variable you have to put in quotes the whole path or the whole variable.
i.e.
set "winscp=C:\Program Files (x86)\WinSCP\WinSCP.com"
echo start "%winscp%"
:: output: start "C:\Program Files (x86)\WinSCP\WinSCP.com"
or
set winscp="C:\Program Files (x86)\WinSCP\WinSCP.com"
echo start %winscp%
:: output: start "C:\Program Files (x86)\WinSCP\WinSCP.com"
Another point, you have to check this file: UploadScript.txt because your script adds new lines rather than remake the file.
change this line to >%scriptPath% echo option batch abort instead of >>%...
Ah, I did not pay attention to the IF EXIST.

FTP batch script is not exiting with error status

There is a ftp command in my batch script :
FTP -n -s:D:\scripts\Test\get.ftp
Where get.ftp contains all ftp commands including "mget abc*".
Issue here is when file(s) of names starting with abc* is not available, mget is not failing. Also, if any other ftp command fails also, the script is not exiting with error status 1. i.e. "FTP -n -s:D:\scripts\Test\get.ftp" exiting without issues.
Not able to make the batch script fail when there is no file to pick up.
Need suggestion if someone has faced similar issue.
-Krishna
The mget command works by obtaining a remote folder listing and parsing the list for the wildcard pattern that you provide. As long as the listing can be obtained successfully,
it is not considered an error if your pattern did not match any of the files on the list.
Your batch script can be setup to compare the local folder listing before and after invoking the ftp command to check if a file was downloaded. You can also use a scripted ftp solution like kermit or ftp script to be able to have more control on error reporting.
