[英]How to list all distinct extensions of tracked files in a git repository?
I'd like to know all distinct extensions of files tracked by git in a given repo, in order to create appropriate .gitattributes
file.我想知道 git 在给定存储库中跟踪的文件的所有不同扩展名,以便创建适当
.gitattributes
文件。
Example output expected:示例 output 预期:
bat
gitignore
gradle
html
jar
java
js
json
md
png
properties
py
svg
webp
xml
yml
What command can I use for that?我可以使用什么命令?
git ls-tree -r HEAD --name-only | perl -ne 'print $1 if m/\.([^.\/]+)$/' | sort -u
When you declare it as an alias, you have to escape $1
: 当您将其声明为别名时,您必须转义
$1
:
alias gitFileExtensions="git ls-tree -r HEAD --name-only | perl -ne 'print \$1 if m/\.([^.\/]+)$/' | sort -u"
This is better than naive find
, because: 这比天真的
find
要好,因为:
.git
directory which contains usually hundreds/thousands of files and hence slows down the search .git
目录,其中通常包含数百/数千个文件,因此减慢了搜索速度 (inspired by How can I find all of the distinct file extensions in a folder hierarchy? ) (受如何在文件夹层次结构中找到所有不同文件扩展名的启发? )
If you have access to PowerShell, here is a nice one-liner which also gives you the count of how many files exist of each type:如果您有权访问 PowerShell,这是一个很好的单行代码,它还可以计算每种类型存在的文件数量:
$ext = @{}; git ls-tree -r HEAD --name-only | Get-Item | %{ $ext[$_.Extension]++ }; $ext
