如何让'git diff'只显示提交消息

Question

How do I use git diff to only show commit messages?

I just want the message of the commit, not the name of the files. I am trying to get a change log in Git.

Answer 1

You could try git log , thus,

git log commitA...commitB

The triple dot notation '...' gives you just the commit messages for all the commits that are reachable from commitA or commitB, but not from both - ie, the diff between commitA and commitB.

You can easily strip down to just the commit message with something like:

git log --pretty=%B commitA...commitB

Some examples

# Show a log of all commits in either the development branch or master branch since they diverged.
git log --pretty=%B development...master

# Ahow a log of all commits made to either commit b8c9577  or commit 92b15da, but not to both.
git log --pretty=%B b8c9577...92b15da

# Show a log for all commits unique to either the local branch master or local version of the origin's master branch.
git co master
git log --pretty=%B master...origin/master

# Show a log for all commits unique to either the local HEAD or local version of the origin's master branch.
git co master
# Hack, hack
git log --pretty=%B HEAD...origin/master

Answer 2

Use:

git log --oneline -n 10

It will print out the last n (10) commits on single lines. Just the commit messages.

You can also combine it with other log parameters, like:

git log --oneline --graph --decorate -n 10

Answer 3

In addition to Simon Clewer's answer:

git log master..dev --no-merges --pretty='format:%cs %s'

It prints only subjects of commits between master and development (without merge commits). Something like this:

2020-12-31 Hot fix
2020-12-30 Change some stuff
2020-12-29 Add the feature

Changes between local and remote branches:

git log HEAD..origin --no-merges --pretty='format:%cs %s'

Answer 4

git log --pretty=%B

will show you the last commit messages.

In case you want to limit the number of commit messages shown by a number, N , you can do this by providing an additionally -N , eg,

git log -3 --pretty=%B

for the last three commit messages.
