为什么`git show`不提供有关重定向标准输出的分支的信息? [英] Why `git show` doesn't provide info about branches for redirected stdout?
问题描述
以下是两个带有结果示例的命令:
Here are two commands with result examples:
$ git show
commit 6f367e05cc6457fd0c0fc59fe0476db06cffb383 (HEAD -> master, tag: v7.32, origin/master, origin/HEAD)
Merge: 94ecf1d8 f3ea52b0
Author: Pupkin <pupkin@server.com>
Date: Fri Dec 13 12:49:12 2019 +0700
Some commit description.
$ echo `git show`
commit 6f367e05cc6457fd0c0fc59fe0476db06cffb383 Merge: 94ecf1d8 f3ea52b0 Author: Pupkin <pupkin@server.com> Date: Fri Dec 13 12:49:12 2019 +0700 Some commit description.
重要的区别:在第二个结果中，没有有关分支的信息-("HEAD-> master，标签:v7.32，origin/master，origin/HEAD)" .
The important difference: in the second result no information about branches - "(HEAD -> master, tag: v7.32, origin/master, origin/HEAD)".
我还尝试了stdout和stderr的重定向，重定向到文件，grep以及其他一些构造.同样的结果，在控制台中显示所有内容，在其他情况下-没有分支信息.
I also tried redirections of stdout and stderr to each other, redirect to file, grep, some other constructions. The same result, in the console showing everything, in other cases - no branches info.
为什么呢?
以及如何强制git返回整个消息?
And how to compel git to return the whole message?
推荐答案
如上述评论中的 @ElpieKay 所述，我需要在命令中使用键--decorate.
As said @ElpieKay in the comment above, I need to use the key --decorate with the command.
从 Git手册:
-decorate [= short | full | auto | no]
--decorate[=short|full|auto|no]
打印出所显示的任何提交的引用名称.如果指定了short，则不会打印ref名称的前缀refs/heads/，refs/tags/和refs/remotes/.如果指定了full，则将打印完整的引用名称(包括前缀).如果指定了auto，那么如果输出将输出到终端，则引用名称显示为好像给出了short，否则不显示引用名称.默认选项为 short .
Print out the ref names of any commits that are shown. If short is specified, the ref name prefixes refs/heads/, refs/tags/ and refs/remotes/ will not be printed. If full is specified, the full ref name (including prefix) will be printed. If auto is specified, then if the output is going to a terminal, the ref names are shown as if short were given, otherwise no ref names are shown. The default option is short.
但是我很确定默认情况下默认使用auto代替short，如手册中所述.
But I'm pretty sure that by default uses auto instead short as it said in manual.
此问题已解决.
