sftp script

[Sftp script]

Hi,
I have set up an sftp script and put it as a cronjob to run at 1:00 am. Now the problem is that sometimes the sftp gets stalled what is the best way to set it such that if the process is running for more than 2 hours stop it and start transfer again.
#########################################
#!/bin/ksh cd /source-directory
trafile=$(ls -altr filename | tail -n1 | awk '{print $9}')
echo "OK, starting...."
sftp machine-name << EOF
cd /destination-directory
put $trafile
quit
EOF
####################################

Use background processing sftp execution to get control to that sftp action.

Try as,

#!/bin/ksh

sftp()
{
sftp machine-name << EOF
cd /destination-directory
put $trafile
quit
EOF
}

cd /source-directory
trafile=$(ls -altr filename | tail -n1 | awk '{print $9}')
echo "OK, starting...."
sftp 1>/dev/null 2>&1 &
pid=$!
time=0

# 7200 is two hours in seconds

if [[ ! -z ps -ef | grep -v grep | grep $pid ]]
then
while [[ $time -eq 7200 ]]
do
sleep 10
if [[ -z ps -ef | grep -v grep | grep $pid ]]
then
let time=7200;
fi
let time=time+10
done
kill -9 $pid
fi

# END
exit 0

It will do that.

Thanks Muthukumar,
But is there any better way of kickstarting the stalled sftp process?
