sed根据行号范围执行替换

测试数据:

personball@vostro:SHELL$cat aaa
<instrumentation
android:name="aaa"
android:name="aaa"
android:name="aaa"
android:targetPackage="bbbb" />
<application
<uses-library android:name="ccc" />
<uses-library android:name="ccc" />
<uses-library android:name="ccc" />
</application>
<application
<uses-library android:name="ccc" />
</application>
<application
<uses-library android:name="ccc" />
</application>
personball@vostro:SHELL$

根据 匹配,行号 范围执行替换:

personball@vostro:SHELL$sed '/instr/,5 s/"[^"]*"/"999"/' aaa
<instrumentation
android:name="999"
android:name="999"
android:name="999"
android:targetPackage="999" />
<application
<uses-library android:name="ccc" />
<uses-library android:name="ccc" />
<uses-library android:name="ccc" />
</application>
<application
<uses-library android:name="ccc" />
</application>
<application
<uses-library android:name="ccc" />
</application>

根据 匹配,相对匹配行号 范围执行替换:

personball@vostro:SHELL$sed '/<appli/,+1 s/"[^"]*"/"999"/' aaa
<instrumentation
android:name="aaa"
android:name="aaa"
android:name="aaa"
android:targetPackage="bbbb" />
<application
<uses-library android:name="999" />
<uses-library android:name="ccc" />
<uses-library android:name="ccc" />
</application>
<application
