Import/Export Config Trees

This topic summarizes how to create a script to automate importing and exporting config tree settings.

Legato currently overwrites private config trees during upgrading. The import/export script is an easy way to create a copy of your config trees so you can reinstate them after installing a new Legato version without rebuilding them.

This code sample shows how you can wrap instapp in a shell script that will automate the import/export functions:

#!/bin/bash

APP_NAME=$1

if [ -z "$APP_NAME" ]
then
    >&2 echo "Application name not specified."
    exit 1
fi


if [ -z "$2" ]
then
    if [ -z "$DEST_IP" ]
    then
        >&2 echo "Device IP address not specified."
         exit 1
    fi
    DEVICE_IP=$DEST_IP
else
    DEVICE_IP=$2
fi


function cfg
{
    CMD=$1
    #echo "Test: "
    ssh root@$DEVICE_IP "/usr/local/bin/config $CMD $APP_NAME:/ ~/$APP_NAME.cfg"
}


cfg export
instapp $APP_NAME.ar7 $DEVICE_IP
cfg import

If you save this script as inst.sh, you can run like this:

$ inst.sh <myApp> <myDeviceIP> 

or

$ export DEST_IP=<myDeviceIP>
$ inst.sh myApp
