Grep lines after match until the end

command-line-interfacegrep

I have following output from git status, how do I grep for everything after Untracked files:

[alexus@wcmisdlin02 Test]$ git status 
# On branch master
#
# Initial commit
#
# Changes to be committed:
#   (use "git rm --cached <file>..." to unstage)
#
#   new file:   app/.gitignore
#   new file:   app/app.iml
#   new file:   app/build.gradle
#   new file:   app/proguard-rules.pro
#   new file:   app/src/androidTest/java/org/alexus/test/ApplicationTest.java
#   new file:   app/src/main/AndroidManifest.xml
#   new file:   app/src/main/java/org/alexus/test/MainActivity.java
#   new file:   app/src/main/res/layout/activity_main.xml
#   new file:   app/src/main/res/menu/menu_main.xml
#   new file:   app/src/main/res/mipmap-hdpi/ic_launcher.png
#   new file:   app/src/main/res/mipmap-mdpi/ic_launcher.png
#   new file:   app/src/main/res/mipmap-xhdpi/ic_launcher.png
#   new file:   app/src/main/res/mipmap-xxhdpi/ic_launcher.png
#   new file:   app/src/main/res/values-w820dp/dimens.xml
#   new file:   app/src/main/res/values/dimens.xml
#   new file:   app/src/main/res/values/strings.xml
#   new file:   app/src/main/res/values/styles.xml
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#   .gitignore
#   .idea/
#   Test.iml
#   build.gradle
#   gradle.properties
#   gradle/
#   gradlew
#   gradlew.bat
#   settings.gradle
[alexus@wcmisdlin02 Test]$

Like this, but without specifying number of lines, like the -A parameter in GNU grep:

[alexus@wcmisdlin02 Test]$ git status | grep -A100 'Untracked files'
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#   .gitignore
#   .idea/
#   Test.iml
#   build.gradle
#   gradle.properties
#   gradle/
#   gradlew
#   gradlew.bat
#   settings.gradle
[alexus@wcmisdlin02 Test]$

Is there a way to do it?

[alexus@wcmisdlin02 Test]$ grep --version

With GNU grep (tested with version 2.6.3):

git status | grep -Pzo '.*Untracked files(.*\n)*'

Uses -P for perl regular expressions, -z to also match newline with \n and -o to only print what matches the pattern.

The regex explained:

First we match any character (.) zero or multiple times (*) until an occurence of the string Untracked files. Now, the part inside the brackets (.*\n) matches any character except a newline (.) zero or multiple times (*) followed by a newline (\n). And all that (that's inside the backets) can occure zero or multiple times; that's the meaning of the last *. It should now match all other lines, after the first occurence of Untracked files.
