RE: SFTP on IBMi

You can use 'expect' as suggested by Jack. What I've done is use the built-in batch script capability of SFTP. Either way, you'll need to understand shell scripting. My SFTP script is quite flexible as I build in in the shell script. I'll include a modified excerpt of the script below:

--------------------------------------------------
eval SFTP_SCRIPT=/work-directory/sftp_script_$$
echo Build the sftp script . . .
. rm $SFTP_SCRIPT
. touch $SFTP_SCRIPT
echo cd ${6} >> $SFTP_SCRIPT
echo put /work-directory/file-name.asc >> $SFTP_SCRIPT
echo quit >> $SFTP_SCRIPT
echo Transmit the file . . .
. sftp -vvv -b $SFTP_SCRIPT -F ${4} ${DEST_ID} if [[ $? -eq 0 ]] ; then
echo file-name.asc sent to ${DEST_ID}:${6}
echo " "
echo File transmission for session ${2} completed normally.
. rm $SFTP_SCRIPT
return
else
echo SFTP error: An error occurred processing
echo - - sftp -vvv -b $SFTP_SCRIPT -F ${4} ${DEST_ID}
exit
fi
--------------------------------------------------

The following variables are key to understanding the script
${6} is the remote directory
${DEST_ID} is the Remote-user-ID and address (In the format UserID@xxxxxxxxxxx)
${4} is an SFTP configuration file (it makes it easier to modify the keys, UserIDs, etc. for testing and changes)
- Many other values are done with variables where I've put literals in above

The first line assigns a unique name to the SFTP script based on the current process ID. Then I try to remove the script file--just in case it already exists. Touch generates the file in a compatible CCSID. ${6} is a variable passed in to the script which contains the remote (destination) directory. I believe the rest should pretty much make sense. I execute the SFTP command with -vvv which gives me a high level of verbosity in the results. That makes it easier to debug what happened after the fact. The leading dot '.' tells BASH to run the SFTP command in the same process (unix/linux by default likes to spawn a new process to do each function).

Does anyone have a program to run SFTP on the IBMi?
