sed命令不显示双引号

Question

I am using "sed" command to replace a string from a ".properties" file in linux shell script. The problem is that it is not showing the double quotes.

Note: I think sed command ignores the double quotes,so is there anyway to explicitly force it to not ignore it.

"Shell Script File"

#!/bin/bash

# First Script
#Include Properties File
. directoryPaths.properties

sed -i "s#EPOLD#$EPNEW#" *Test*

Properties File:

EPNEW="jms:/Queue?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory&java.naming.provider.url=tcp://localhost:61616&transport.jms.DestinationType=queue format="pox" "

File:

<?xml version="1.0" encoding="UTF-8"?>
    <endpoint xmlns="http://ws.apache.org/ns/synapse" name="Component">
        <address uri=EPOLD/>
    </endpoint>

Current Result:

<?xml version="1.0" encoding="UTF-8"?>
<endpoint xmlns="http://ws.apache.org/ns/synapse" name="Component">
    <address uri=jms:/Queue?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactoryGLBookingService_EPLOCALamp;java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactoryGLBookingService_EPLOCALamp;java.naming.provider.url=tcp://localhost:61616GLBookingService_EPLOCALamp;transport.jms.DestinationType=queue format=pox />
</endpoint>

Expected Result:

<?xml version="1.0" encoding="UTF-8"?>
    <endpoint xmlns="http://ws.apache.org/ns/synapse" name="Component">
        <address uri="jms:/Queue?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactoryGLBookingService_EPLOCALamp;java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactoryGLBookingService_EPLOCALamp;java.naming.provider.url=tcp://localhost:61616GLBookingService_EPLOCALamp;transport.jms.DestinationType=queue format="pox" " />
    </endpoint>

Answer 1

Assign your variable by inserting literal double quotes:

EPNEW='"jms:/Queue?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory&java.naming.provider.url=tcp://localhost:61616&transport.jms.DestinationType=queue format="pox" "'

Your assignment is this:

EPNEW="jms:/Queue?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory&java.naming.provider.url=tcp://localhost:61616&transport.jms.DestinationType=queue format="pox" "

Which will leave this value in EPNEW :

jms:/Queue?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory&java.naming.provider.url=tcp://localhost:61616&transport.jms.DestinationType=queue format=pox

Answer 2

Try with quotes in sed:

sed -i "s#EPOLD#\"$EPNEW\"#" *Test*

Your quotes is getting missed when you source your properties file and not ignored by sed.
