Why is my batch script using SFTP only running the first line? - batch-file

I have a batch script, in which I am logging into an SFTP server and moving around some files. To do this, I've copied the public key so that there's no user interaction between me and the server. The script should just enter the hostname, the username and the port, and then move around some files, without entering a password. However, when I run my script, only the first line is running (the sftp command).
Here is the script:
sftp -oPort=PORT USER#HOST_IP_ADDRESS
pwd
cd mcservers/earth/plugins
pwd
rm SomeFile.jar
put "C:\Users\USER\Documents\THE_PATH\target\AnotherFile.jar"
exit
I've tried putting an ampersand after my lines but it didn't work.
What can I do?

Batch files run each line as a command, wait for them to complete and then execute other lines. They do not simulate keyboard input.
So what your batch file does it that it runs sftp in an interactive mode and waits for it to complete. That never happens, until you type bye.
If you want to automate the sftp commands, one way to do that is to store the sftp commands to separate file (sftp.txt) and execute it using -b switch:
sftp -b sftp.txt -oPort=PORT USER#HOST_IP_ADDRESS
This is a common misconception that you might face with any other SFTP client (or any other command/program that has its own subcommands or ay other input).
For example: WinSCP script not executing in batch file

FileZilla Pro CLI Batch command file not executing

I am currently attempting to use FileZilla Pro CLI on a Windows machine to connect and upload to a site in that is working in the Site Manager.
The issue is, the command below works perfectly when pasting it directly into the cmd line. However when saving it as a batch file, it simply just gets to the fzcli> prompt and then nothing happens.
The two line breaks are on purposes to override the requirement for a password and it works perfectly when pasted in.
Does anyone know if this is a cmd line issue, or if my commands need to be different to work in batch file mode?
fzcli
connect --site 0testsite01
put C:/inetpub/wwwroot/websites/sftp/files/customer/test-01.txt /test-sftp/testuser01/test/test-01-uploaded.txt
PAUSE
Your batch file executes fzcli in an interactive mode. The fzcli then waits for you to interactively enter the commands. Only after you would exit the fzcli, the batch file would continue. And fail, as it will try to execute connect as a batch file command. The fzcli does not know about the batch file. Nor does the batch file interpreter know about the fzcli commands.
It's a common misconception. You will find plenty of similar questions basically about scripting any tool that has its own commands. For example: sftp, ftp, psftp, winscp.
To provide commands to fzcli, it seems that you need to use --script switch. The fzcli documentation gives this example:
fzcli --mode standalone --script C:\Scripts\script-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.

Automating putty with .bat file [duplicate]

I want to run a few shell commands every time I SSH to a server via PuTTY. I'm connecting to a production web server managed by someone else, and I don't want to store my own scripts there.
I see the option Connection > SSH > Remote Command, but if I put my initialization commands there, after starting the session, it closes immediately after the commands execute. How can I run the Remote Command, and then keep the session open so I can continue using it?
The SSH session closes (and PuTTY with it) as soon as the command finishes. By default the "command" is a shell. As you have overridden this default "command" and yet you want to run the shell nevertheless, you have to explicitly execute the shell yourself:
my-command ; /bin/bash
See also Executing a specific command on the server.
One option to go is set up your putty remote command like this:
ls > dir.ls & /bin/bash
In this example command you want to run is "ls > dir.ls" what creates file dir.ls with content of directory listing.
And as you want to leave shell open you can add aditional command "/bin/bash" or any other shell of your choice.

Execute sftp commands on remote server using batch file and PuTTY

I have to transfer a file from one server to another. I log in to the first one with PuTTY and then type this:
sftp -v -oIdentityFile=path username#host
cd path
put file
Everything works perfectly! Now I'm trying to do it with a batch file. In the .bat I have:
putty.exe -ssh host1 -l username1 -pw password1 -m script.txt
In the script.txt file:
sftp -v -oIdentityFile=path username2#host2
cd path
put file
exit
It connects to the server number two but then it stops. The prefix sftp> does not appear and it does not read the following lines. Do you have any suggestion?
The remote shell takes the commands and executes them one by one. So it executes the sftp, waits for it to exit (what it never does) and only then it would execute the cd command (but in shell, not in the sftp), the put (failing as that's not a shell command), etc.
If your intention was to simulate typing the commands as on a terminal, use Plink and input redirection.
The Plink (PuTTY command-line connection tool) is a tool from PuTTY package that works like PuTTY, but it is a console, not GUI, application. As such it can use input/output redirection. And anyway, the Plink is the tool to automate tasks, not PuTTY.
plink.exe -ssh host1 -l username1 -pw password1 < script.txt

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.
