automate sftp in sun solaris.
Hi,

I'm using Sun Solaris OS. I have configured sftp and can exchange files in command prompt. Now when I try to automate it in ksh script, facing issue as I want to capture the status if the transfer was successful or not. So tried sftp -b and sftp -B option but its not working.

The following is the code:
Code:
> cat testing_sftp.ksh
#!/usr/bin/ksh
echo " sftp -b tempsftp1.batch user@server " > tempsftp2.ksh
echo " put hello.txt " >> tempsftp1.batch
echo " quit " >> tempsftp1.batch
chmod 776 tempsftp2.ksh 
ksh tempsftp2.ksh > tempsftp3.log

i'm not able to capture any status.

when i try the above on the command prompt getting error saying -b or -B option not supported.
Code:
> sftp -b tempsftp1.batch user@server
sftp: illegal option -- b
usage: sftp [-1vC] [-osshopt = value] [user@]host

This when tried in hp-ux it worked, but its not working for solaris
So please let me know how can I capture the o/p.

Thanks in advance!

This seems a rather indirect way to do it. Why not just run it, instead of echoing commands into a file that runs it and running that? Putting it all into echo statements like that also makes it rather difficult to tease apart what you're actually doing.

Unfortunate that your version of sftp doesn't support -b but there's ways around that.

The chmod is pointless if you're running it with 'ksh scriptfile' by the way.

How about:

Code:
#!/bin/ksh

# This feeds the lines following <<EOF into sftp on standard
# input, this is called a 'here-document'.
# Errors are saved to err.log, stdout to out.log
sftp username@host > out.log 2> err.log <<EOF
put hello.txt
quit
EOF

Also, I suspect you're not capturing the errors because they're printed to standard error, not standard out.

Thanks it worked!
I'm able to capture the errors but unfortunately when the transfer is successful I don't get any response, (even in command prompt).
Is there any way to achieve this, to force system to respond ? also I don't get any message when the file already exist, it simply overwrites it.

Check the return status after the command. [ "$?" -eq 0 ] && echo "Transfer successful"

Do you mean 'respond' in any other way than print success or failure?

That's what scp does, yes. If you want to check if it exists first, you have to do so yourself.

Unfortunately not having -b makes this a lot harder: You can't check the exit status, you have to process the text of its output!

Code:
$ sftp localhost <<EOF
ls FARG
EOF
Couldn't stat remote file: No such file or directory
Can't ls: "FARG" not found
