git show 명령어로 commit 정보 확인

gittips

git show 명령어를 사용하여 commit 정보 및 변경 사항을 확인할 수 있습니다.

1. 특정 commit 정보 확인

git show <commit id>는 commit id의 정보 및 수정 내용을 보여줍니다.

$ git show 3cb225dc74b9f0faf0858fd4602ceaadb3e9d30c

commit 3cb225dc74b9f0faf0858fd4602ceaadb3e9d30c
Author: Peiyong Lin <lpy@google.com>
Date:   Mon Sep 28 23:17:37 2020 -0700

    [GraphicsEnvironment] Avoid null access.

    Currently when debug layer apk is not installed, GraphicsEnvironment
    logs the message and proceeds, which results in null pointer access
    crash when later trying to access primaryAbi. Avoid null access by an
    early return statement.

diff --git a/core/java/android/os/GraphicsEnvironment.java b/core/java/android/os/GraphicsEnvironment.java
index df1f1b21eba..e77b163743f 100644
--- a/core/java/android/os/GraphicsEnvironment.java
...

commit id는 7자리까지만 입력해도 됩니다.

$ git show 3cb225d

commit 3cb225dc74b9f0faf0858fd4602ceaadb3e9d30c
Author: Peiyong Lin <lpy@google.com>
Date:   Mon Sep 28 23:17:37 2020 -0700

2. 최신 commit 정보 확인

git show는 가장 최신 commit의 정보를 출력합니다.

$ git show

commit 8c3b567c36ef56e03a67aac83fe045c4b239217e (HEAD -> master, origin/master, origin/HEAD)
Merge: 4f94f12cba2 f7dc3f6788d
Author: Nathan Harold <nharold@google.com>
Date:   Fri Dec 18 00:38:04 2020 +0000

    Merge "Fix permission on TM#isDataEnabled"

HEAD는 가장 최신 commit을 가리키기 때문에, 아래와 같이 입력해도 됩니다.

$ git show HEAD

commit 8c3b567c36ef56e03a67aac83fe045c4b239217e (HEAD -> master, origin/master, origin/HEAD)
Merge: 4f94f12cba2 f7dc3f6788d

Date:   Fri Dec 18 00:38:04 2020 +0000

    Merge "Fix permission on TM#isDataEnabled"

3. 최신 바로 이전 commit 정보 확인

HEAD^는 가장 최신 commit의 이전 commit을 가리킵니다. HEAD^^^은 최신 commit의 3개 전의 commit을 가리킵니다.

$ git show HEAD^

commit 4f94f12cba24c7d2c03447c742df5cf3a894307a
Merge: c0de8cfcfad 3fa9158be79

    Merge "MediaCodecInfo: do not alter performance points for 32-bit processes"

3.1 git show HEAD~1

HEAD~1은 HEAD^과 동일한 의미입니다. HEAD~3은 HEAD^^^과 동일한 의미가 됩니다.

$ git show HEAD^^^
