Here is the syntax for an SFTP setup that I created that reads the commands out to a temp file and then runs the SFTP using the tmp file and removes. You could always keep the batch files as well, but I didn't want to have to manage tons of them. You need Passwordless Pubkey authentication though.

I bolded the part below. I don't believe SFTP can read teh STDIN like FTP scripts, but I could be mistaken.


Code:
#!/bin/bash

#SFTP_PUSH.sh
#
#       This script is for copying files from location where
#       they are dropped to SFTP server

#Before implementing you can run the create_dirs script to create the archive and log directories

##### Update information below ####
CLIENT=       #client name for directory location
FEEDNAME=     #feed name for directory location
ORIGLOC=  #pickup location
DESTSERV=  #destination server name
DESTUSER=    #username for destination server
DESTLOC=/

#### End User input ####
ARCHLOC=/ftp_custom/archives/$CLIENT/$FEEDNAME
LOGFILE=/ftp_custom/logs/$CLIENT/$FEEDNAME.log
GETDATE=`date`


#       echo start date to log

echo "Started script at $GETDATE" >> $LOGFILE

# Check if items in directory then execute, else (at bottom) exit

if [ "$(find $ORIGLOC -type f)" ]; then


#       List files out to log

echo " The following file was found and is about to be transferred..." >> $LOGFILE

ls -l $ORIGLOC >> $LOGFILE

#       Copy files to archive location

cp -p $ORIGLOC/* $ARCHLOC >> $LOGFILE

#       Copy files to new location using temporary sftp batch file

cd $ORIGLOC
echo cd $DESTLOC > /tmp/$FEEDNAME.sftp
echo 'mput *' >> /tmp/$FEEDNAME.sftp
echo bye >> /tmp/$FEEDNAME.sftp
sftp -b /tmp/$FEEDNAME.sftp $DESTUSER@$DESTSERV >> $LOGFILE
if [ $? -eq "0" ]; then
        echo Files successfully transfered at $GETDATE >> $LOGFILE
        rm -f $ORIGLOC/* >> $LOGFILE
else
        echo File transfer failed at $GETDATE >> $LOGFILE
fi

rm -fv /tmp/$FEEDNAME.sftp

# Echo finish date to log
echo "Finished script at $GETDATE" >> $LOGFILE
exit 0
 # End Script if directory empty
        else
        echo "No files to process $GETDATE" >> $LOGFILE
        echo "Finished script at $GETDATE" >> $LOGFILE
        exit 0
        fi

NAME
rbash - restricted bash, see bash(1) RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow- ing are disallowed or not performed: o changing directories with cd o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV o specifying command names containing / o specifying a filename containing a / as an argument to the . builtin command o specifying a filename containing a slash as an argument to the -p option to the hash builtin command o importing function definitions from the shell environment at startup o parsing the value of SHELLOPTS from the shell environment at startup o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators o using the exec builtin command to replace the shell with another command o adding or deleting builtin commands with the -f and -d options to the enable builtin command o using the enable builtin command to enable disabled shell builtins o specifying the -p option to the command builtin command o turning off restricted mode with set +r or set +o restricted. These restrictions are enforced after any startup files are read. When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script. SEE ALSO
