Question

I am attempting to manipulate an Adobe Reader plist file on OS X to stop auto update checking.
This needs to be scripting so I can affect the change on 700+ Macs.

I have:

#!/bin/bash
plutil -convert xml1 /Users/username/Library/Preferences/com.adobe.Reader.plist

to convert the file for text editing.

I found this elsewhere for multi-line search and replace:

sed -n '1h;1!H;${;g;s/<h2.*</h2>/No title here/g;p;}' sample.php > sample-edited.php;

The source file has repetitions of similar data, so I need to find the occurrence after the entry CheckForUpdatesAtStartup

Here is a portion of the file:

<key>AutoUriDetect</key>
                    <array>
                            <integer>0</integer>
                            <true/>
                    </array>
                    <key>CheckForUpdatesAtStartup</key>
                    <array>
                            <integer>0</integer>
                            <true/>
                    </array>
                    <key>CheckGPUAtStartup</key>
                    <array>
                            <integer>0</integer>
                            <false/>
                    </array>

So I need to replace the true to false for the CheckForUpdatesAtStartup array.

Answer 1

awk > outfile '/CheckForUpdatesAtStartup/, /<(true|false)\/>/ {
  sub(/true/, "false")
  }1' infile
