Editing plist file using shell script (5)

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" "     1.0.dtd">
<plist version="1.0">

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)

Using sed:

sed -i '' '/<key>BundleIsRelocatable</{n;s/true/false/;}' file.plist

If the plist is not XML, run plutil -convert xml1 file.plist first.

A bit late, but for the record, you just need to specify the absolute path AND add the .plist extension to the filename. If you are running your script in same directory that the plist file, your case would be translated into:

defaults write $PWD/YourPlistFilename.plist BundleIsRelocatable -bool false

For String use

plutil -replace NameOfProperty -string "yourNewValue" plistFileName.plist

The last response of Phil-CB here should be usefull.

Using PlistBuddy, a simple tutorial HERE.

 /usr/libexec/PlistBuddy -c "Set :BundleIsRelocatable bool false" plistfilename.plist

It can run as ONE command line to update the key/value. I use it to update CFBundleVersion generally, which can be found in this post.
