Comparing p-lists (iOS Property List Files)

In OS X and iOS programming frameworks, property list files are used to store information about bundles and applications. Analyzing .plist files can tell you a lot about an application. It is often useful to compare content and view modifications to .plist files to understand what has changed between versions of an application.

---

• list paths of .plist files modified between 2 branches

# first do a dry-run (only print the commands that will be applied)
for f in *; do echo mv "$f" $(printf '%s' "$f" | tr -d '0123456789'); done

# run it for real (modifications done in-place)
