如何通过 shell 脚本创建简单的文件版本控制？

如果内容发生了变化，是否可以复制文件以实现简单的版本控制？

myFolderInclSubfolderBackupWithVersioning.sh < source folder> < dest >

例如源文件夹

  • file1.jpg 100K（今天）

目标上的文件夹，例如外部硬盘：

  • file1.jpg 大小 100K（今天）
  • file1(2).jpg 大小 99K （昨天）
  • file1(1).jpg 大小 101K （2个月前）

谢谢你！

以下设置有效：

  • 工作目录work（可以有子目录）
  • 工作目录旁边的备份目录backup（在实际情况下，您可能将备份目录放在外部驱动器中）

此命令将从 备份work到backup：

cp -r --backup=t work/* backup/

例子

$ find
.
./work
./work/file:name
./work/foo.sh
./work/file-0
./work/dollarfraga1
./work/dollarfraga2
./work/sub
./work/sub/hello
./work/dollarfraga
./backup
$ cp -r --backup=t work/* backup/
$ find
.
./work
./work/file:name
./work/foo.sh
./work/file-0
./work/dollarfraga1
./work/dollarfraga2
./work/sub
./work/sub/hello
./work/dollarfraga
./backup
./backup/file:name
./backup/foo.sh
./backup/file-0
./backup/dollarfraga1
./backup/dollarfraga2
./backup/sub
./backup/sub/hello
./backup/dollarfraga
$ cp -r --backup=t work/* backup/
$ find
.
./work
./work/file:name
./work/foo.sh
./work/file-0
./work/dollarfraga1
./work/dollarfraga2
./work/sub
./work/sub/hello
./work/dollarfraga
./backup

可以cp这样使用，但我建议您学习rsync，这是一个更高级的工具，用于复制目录结构（包括备份），或者可能是一些专用的备份工具。rsync而其他工具只会复制新的或已更改的文件。
