I advise you to run sftp with -v option  It becomes much easier to fathom what is happening   The manual clearly states      The final usage format allows for automated sessions using the -b   option         In such cases  it is necessary to configure non-interactive authentication         to obviate the need to enter a password at connection time  see        sshd 8  and ssh-keygen 1  for details     In other words you have to establish a publickey authentication  Then you ll be able to run a batch script   P S  It is wrong to put your password in your batch file

You need to use the command pscp and forcing it to pass through sftp protocol  pscp is automatically installed when you install PuttY  a software to connect to a linux server through ssh  When you have your pscp command here is the command line  pscp -sftp -pw  lt yourPassword gt   quot  lt pathToYourFile s  gt  quot   lt username gt   lt serverIP gt   lt PathInTheServerFromTheHomeDirectory gt   These parameters  -sftp and -pw  are only available with pscp and not scp  You can also add -r if you want to upload everything in a folder in a recursive way

If you are generating a heap of commands to be run  then call that script from a terminal  you can try the following   sftp login host  lt   path to command list   You will then be asked to enter your password  as per normal  however all the commands in the script run after that   This is clearly not a completely automated option that can be used in a cron job  but it can be used from a terminal

You ll want to install the sshpass program  Then   sshpass -p YOUR PASSWORD sftp -oBatchMode no -b YOUR COMMAND FILE PATH USER HOST  Obviously  it s better to setup public key authentication  Only use this if that s impossible to do  for whatever reason

You mention batch files  am I correct then assuming that you re talking about a Windows system  If so you cannot use sshpass  and you will have to switch to a different option  Two of such options  that follow diametrically opposite philosophies are       psftp  command-line tool that you can call from within your batch scripts  psftp is part of the PuTTY package and you can find it here http   www chiark greenend org uk  sgtatham putty download html    Syncplify me FTP Script  a scriptable FTP S and SFTP client for Windows that allows you to store your password in encrypted  profile files   check it out here http   www syncplify me products ftp-script    Either way  switching from password to PKI authentication is strongly recommended
