查找按字典顺序跟随我的所有分支

Question

我想编写一个 POSIX shell (

/bin/sh

)，它将输入分支名称。这些分支是发布分支，其格式为

release/yymmDD-HHMMSS

，例如

release/240321-170138

、

/release/240405-095914

。 A

git branch -A | grep release

为我找到了所有这些：

origin/release/230823-184353
origin/release/230825-154255
origin/release/230829-112434
origin/release/230905-101013
origin/release/230913-114212
origin/release/230915-105323
origin/release/230920-115230
origin/release/230927-115028
origin/release/230927-125843
origin/release/231016-145729
origin/release/231019-110314
origin/release/231030-150735
origin/release/231102-125814
origin/release/231109-114532
origin/release/231122-120112
origin/release/231123-140553
origin/release/231204-143206
origin/release/231213-153646
origin/release/231229-123237
origin/release/240112-160116
origin/release/240123-093125
origin/release/240201-171058
origin/release/240209-140214
origin/release/240216-121012
origin/release/240222-134817
origin/release/240307-115055
origin/release/240320-111003
origin/release/240321-170138
origin/release/240405-095914

现在假设我的脚本已被赋予分支名称

release/240216-121012

。我想以列表或数组的形式（不确定 POSIX shell 中正确的术语是什么）接收按时间顺序跟随此分支名称的所有分支，在本例中这也意味着按字典顺序，至少到 2099 年：

origin/release/240222-134817
origin/release/240307-115055
origin/release/240320-111003
origin/release/240321-170138
origin/release/240405-095914

什么是快速而优雅的方法来做到这一点？我目前设想将所有这些结果放入一个数组中，然后从末尾向后循环，直到遇到我想要的分支。也许带有

awk

或

sed

和

xargs

的东西可以在这里解决问题？

Answer 1

一种方法，使用

sort

确保正确的顺序，使用

sed

标记入口点，使用

awk

打印标记后的行（此处为

<=

）。

% set="release/240216-121012"

% sort -t / -Vk 3 files | 
    sed "s|${set}|PP<=|" | 
    awk 'set==1{print} /PP<=/{set=1}'
origin/release/240222-134817
origin/release/240307-115055
origin/release/240320-111003
origin/release/240321-170138
origin/release/240405-095914

数据

更改顺序以确保排序按预期进行
