Replacing in SED
I want to change the false in Node 1 to true. How do I do that?
<Node1>
<Usage>false</Usage>
<Url>ABC</Url>
</Node1>

<Node2>
<Usage>false</Usage>
<Url>DEF<Url>
</Node2>

Try:
Code:
/tmp # echo "
> <Node1>
> <Usage>false</Usage>
> <Url>ABC</Url>
> </Node1>
>         
> <Node2>
> <Usage>false</Usage>
> <Url>DEF<Url>
> </Node2>" | sed -e 's/false/true/g'

<Node1>
<Usage>true</Usage>
<Url>ABC</Url>
</Node1>

<Node2>
<Usage>true</Usage>
<Url>DEF<Url>
</Node2>

or:

Code:
sed -e 's/false/true/g' file > file.new

Regards,
Nir
