Script to open a saved file and modify the content

I am looking for a script where I need to open a file and modify the data like changing the parameters.Can anyone help me?

open a file software.rsp . It already contains following data.
parameter = false
threads=100
user= demf

The above should be changed to
paramter=true
thread= 133
user = deefs

threads=330
user= demf

Don't use the -i option of sed for testing (dry run)
Code:
sed -i -e 's/parameter.*/parameter=true/' -e 's/threads.*/threads=133/' -e 's/user.*/user=deefs/' software.rsp
echo "inventory_loc=/folder1/subfo1/Or/Inventory
inst_g=webspher" > /folder/subfolder/file
