I am using AIX/Unix that is making two FTP calls one a simple FTP the other a Secure FTP (SFTP).

My script needs to be able to be able to determine if the FTP was successful or not.  Does anyone have any ideas or examples on how I could try this?  Right now, I'm just trying to test the connection by pinging the server.  Once I get it to work, I'll expand it to use an FTP command.  This is what I have so far

 

STATUS=`ping -v -c 1 servername`

if [ "$(echo $STATUS | grep -c "NOT FOUND")" -ge 1 ]
 then
   echo "No Connection"
 else
   echo "Connection successful"

It works fine if I use the correct server name but if I alter the name to test the "NOT FOUND" condition, I still get a "Connection successful" message.

Brian,
This issue is you’re testing the return code status of the echo against the 1. Echo will ALWAYS succeed, as it will ALWAYS return zero

You’ll need to change the grep to do the compare of the string directly, not check an return code

I've got a working example of the ftp command..

if [ -s ${SRCFILE} ]; then

mv ${SRCFILE} ${WRKFILE}
cat ${WRKFILE}|tr [a-z] [A-Z] > ${SRCFILE}

RESULT=`ftp -inv < open ftp.domain.com
user user_id password
ascii
put ${SRCFILE} ${TRGFILE}
bye
EndFTP`

echo "${RESULT}" >> ${TMPFILE}


Then check the resulting variable like below:
grep -i "226 Transfer complete" ${TMPFILE} > /dev/null
if [ $? -eq "0" ]; then
grep -i "bytes sent" ${TMPFILE} > /dev/null
if [ $? -eq "0" ]; then
STAT="0"
fi
fi

else
echo "FTP: ${SRCFILE} does not exist." >> ${TMPFILE}
fi

I was able to get that to work. Thanks a lot for your help Greg! NOW, do you have something similar for SFTP? This doesn't seem to work for that.

Here's an excerpt of the pertinent pieces of an sftp script

sftp -i ${ftpKey} -b - ${ftpUserID}@${ftpHost} <

        lcd ${LPath}

        cd ${RPath}

        get ${RFile} ${LFile}

        rm ${RFile}

        bye

EOF

 

sftpRC=$?

echo ' '

echo '     SFTP Return Code:  ' $sftpRC

echo ' '

 

if [ $sftpRC == 0 ]; then

    echo '     SFTP Successful'

        echo ' '

else

    echo '     Error - SFTP Failed!'

        echo ' '

    exit 9

fi
