Re: monitoring batch shell scripts

We have something similar. We use LFTP so we can use user/password or user/certificate, but same mechanism.

Here's my script:

#!/usr/bin/bash

user=USUSND
password=PWDUSUSND
ipadd=MYSERVERIPADDR
predir=/OUTBOX
postdir=/OUTBOX_DONE/

workdir=/home/ESSELWARE
mailaccount='useralert@xxxxxxxxxxxxxx:Passw0rd'

for i in {1..$5}
do
        retcode=0
        lftp -C -c "open -u $user,$password  sftp://$ipadd;lcd $predir;cd $remotedir;mput *"
        retcode=$?
        if [ $retcode -eq 0 ]
        then
        ## Exit code 0 means no errors found. Exiting loop ##
                i=$retries
                break
        else
        ## Wait 10 seconds before retry ##
                sleep 10
        fi
done

## Check for errors ###
if [ $retcode -gt 0 ]
then
## Email alert when error found ##
        cp $workdir/alertsmail.txt $workdir/alertsmail2.txt
        ls -la $predir  >> $workdir/alertsmdtk2.txt
        echo "Código de salida : $retcode ">>$workdir/alertsmail2.txt

        curl --url $mailserver --ssl-reqd --mail-from $mailfrom --mail-rcp $receptor --user $mailaccount --insecure --upload-file $workdir/alertsmail2.txt

        mv $predir/* $postdir

Good luck

Let's say you have a CL pgm that does a CALL QP2BATCH(xx.sh <parms>) where control goes over to the *ix side of the world.

Let's say that the xx.sh script runs and sFTP, python, or perl script.

What happens if one of these err out.  How would the CL calling process know?

We had one case where an sFTP script was erring out because the server was displaying a connection msg.  Once we piped std err to a file all completed normally.

Thanks,
