Editing plist file using shell script

Question

I have used pkgbuild to create a default Component Property List file. The file looks like:

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-     1.0.dtd"> <plist version="1.0"> <array>     <dict>         <key>BundleHasStrictIdentifier</key>         <true/>         <key>BundleIsRelocatable</key>         <true/>         <key>BundleIsVersionChecked</key>         <true/>         <key>BundleOverwriteAction</key>         <string>upgrade</string>         <key>RootRelativeBundlePath</key>         <string>MyApp.app</string>     </dict> </array> </plist> 

I want to modify this file by using shell script. I tried using defaults write but it didn't do anything.

What is the way to do it?(For example: I want to set BundleIsRelocatable to false)

Also:

plutil -replace BundleIsRelocatable -bool false plistfilename.plist
