Command line tools for managing binary Apple property list (.plist) files.
Version 1.0 - May 15, 2005
A simple rule for use of the scripts: only use them if you need to. Unfortunately, Apple's plutil provides no simple way of checking whether a .plist file is ASCII (XML) or binary before performing conversions. So, try grepping or editing the file in question using standard tools before reverting to the use of these scripts.
These scripts, written in Perl, are quite simple in nature. I spend a lot of time cleaning out and exploring preference files when administering Mac OS X machines, and Mac OS X 10.4's propensity toward binary .plist files made this process much more tedious.
The apparent alternative is a GUI, such as Apple's very own "Property List Editor" application. While such tools have their places, I am not a fan of managing .plist files with a GUI, especially when I don't necessarily know what I want to do until I perform a grep or two. Hence these scripts, which should work in any version of Mac OS X, but are ideally suited to Mac OS X 10.4 and higher. I wrote them to avoid painful retyping of Apple's plutil command. All three scripts run plutil in one form or another to get the job done, and their use should be obvious to just about anyone familiar with a UNIX command line.
Here's a basic overview of each command (usage for all three: command filename.plist):
Those who prefer another editor (such as pico) may wish to edit line 58 of /usr/bin/pledit to use their favorite editor. I just happen to like vim.
The three scripts are installed in /usr/bin. Installing requires administrative access, and the scripts are installed with permissions of 755 (rwxr-xr-x). To uninstall, simply remove these three files. You may elect to remove the "PLTools.pkg" file in your /Library/Receipts folder as well.
