Better way of getting a GIT commit message by short hash?
提问by ehime
I am currently getting my commit message for a certain commit hash by using this below:
我目前正在通过使用以下内容获取某个提交哈希的提交消息：
hash='b55da97'
git log --pretty=oneline ${hash} | grep "${hash}" | awk '{ print }'
These seems extremely inefficient though. Is there a smarter or cheaper way to do this, or am I stuck with grepping and awking?
不过，这些似乎效率极低。有没有更聪明或更便宜的方法来做到这一点，还是我坚持使用 grepping 和 awking？

git logtakes (among other things):
git log需要（除其他外）：
-n numto limit the number of commits shown: choose 1 (and ifnumis 9 or less you can just write-num, hence,-1, for short)--pretty=format:string with directivesto change the log output format. The%sdirective gets the commit "subject", which is what you also get withoneline.
-n num限制显示的提交数量：选择 1（如果num是 9 或更少，您可以只写，因此，简称 ）-num-1--pretty=format:string with directives更改日志输出格式。该%s指令获取提交“主题”，这也是您使用oneline.
Hence: git log -n 1 --pretty=format:%s $hash(or git log -1 --pretty=format:%s) will do the trick here.
因此：（git log -n 1 --pretty=format:%s $hash或git log -1 --pretty=format:%s）将在这里起作用。
For a complete list of format directives, see the git log documentation, under "PRETTY FORMATS" (about halfway down).
有关格式指令的完整列表，请参阅“PRETTY FORMATS”下的git log 文档（大约一半）。

Depending on how much of the commit message you actually want, there are several pretty-format specifiers that you can use:
根据您实际想要的提交消息的数量，您可以使用几个漂亮的格式说明符：
· %s: subject
· %f: sanitized subject line, suitable for a filename
· %b: body
· %B: raw body (unwrapped subject and body)
So something like git log -1 --pretty=format:%b <hash>, or use one of the other specifiers (I think %sis probably closer to what you are doing now). The -1limits git logto just the one commit, rather than walking the history tree.
所以像git log -1 --pretty=format:%b <hash>, 或使用其他说明符之一（我认为%s可能更接近你现在正在做的事情）。该-1限制git log只是一个承诺，而不是走在历史树。

I like having the important stuff dumped into a single line... Here's what I use, built off other answers on this page:
我喜欢将重要的内容转储到一行中……这是我使用的内容，基于此页面上的其他答案：
git_log_for_commit.sh
git_log_for_commit.sh
IT=$(git log -1 --pretty=format:"%an, %s, %b, %ai" $*)
echo "$IT"
output

An even shorter answer than is listed here is
比这里列出的更短的答案是
git log --pretty=oneline {your_hash} | grep {your_hash}
git log --pretty=oneline {your_hash} | grep {your_hash}

This may short it some
这可能会缩短一些
git log --pretty=oneline ${hash} | awk '##代码##~var {print }' var="${hash}"
