Keeping a copy of a file in a same directory
提问by user974802
I am working on linux scripts , Assume that the directory is consisting of these following scripts .
我正在处理 linux 脚本，假设该目录由以下这些脚本组成。
ls *.sh
test.sh
MyScripts.sh
My question is , before making any modifications to test.sh script , i want to keep a backup copy of it , so that if anything messes up , i will be not screwed up . please tell me how can i keep a copy of test.sh in the same directory ?? before making any modifications to the actual file test.sh .
我的问题是，在对 test.sh 脚本进行任何修改之前，我想保留它的备份副本，这样如果出现任何问题，我就不会被搞砸。请告诉我如何将 test.sh 的副本保存在同一目录中？在对实际文件 test.sh 进行任何修改之前。
Thank you very much .
非常感谢 。

The usual approach is to
通常的做法是
cp test.sh test.sh~
(or test.sh.bckor whatever naming convention). In fact, any decent editor should have an option to do this automatically for you. Vim does it by default (saves a backup name filename~ on modification)
（或test.sh.bck任何命名约定）。事实上，任何体面的编辑器都应该有一个选项可以为您自动执行此操作。Vim 默认这样做（在修改时保存备份名称 filename~）
May I heartily suggest a version control solution for this purpose instead?
我可以衷心地为此目的建议一个版本控制解决方案吗？
