增量發版腳本
[DateTime] 表示一個由時間日期信息生成的變量值，作爲目錄名稱。
| 序號 | 腳本 | 說明 |
|---|---|---|
| 1 | zcw_mkdir4bak-2.2.sh | 創建目錄 |
| 2 | zcw_bak4release-3.2.sh | 備份目錄 |
| 3 | zcw_replace4release-2.0.sh | 替換文檔 |
| 4 | zcw_Virtualfile-2.0.sh | 處理新增文件 |
1 zcw_mkdir4bak-2.2.sh
用法，直接執行：
[root@right .donatello]# bin/zcw_mkdir4bak-2.2.sh Create directory, ok. >> /home/can_remove/20161229125912 Create directory, ok. >> /home/zcw_backup_op/20161229125912
創建目錄是爲了備份文件，創建的目錄位於/home/zcw_backup_op/,/home/can_remove/下。
創建的目錄名稱完全由“日期時間”信息組成，例如：
[root@right .donatello]# cd /home/zcw_backup_op/ [root@right zcw_backup_op]# ll total 4 drwxr-xr-x. 3 root root 16 Dec 26 17:04 20161226100101 drwxr-xr-x. 3 root root 17 Dec 26 15:51 20161226135120 drwxr-xr-x. 3 root root 16 Dec 26 17:07 20161226170720

2 zcw_bak4release-3.2.sh
用法，需要一個參數，該參數必須是個存在的目錄。如：
[root@right .donatello]# bin/zcw_bak4release-3.2.sh Usage: "bin/zcw_bak4release-3.2.sh /path/to/directory" The command must have a parameter that must be an existing, accessible directory at the run time. [root@right .donatello]# bin/zcw_bak4release-3.2.sh /data003/zhaocai Usage: "bin/zcw_bak4release-3.2.sh /path/to/directory" The command must have a parameter that must be an existing, accessible directory at the run time. [root@right .donatello]# bin/zcw_bak4release-3.2.sh /home/zhaocai/release/zhaocai/lib/ The current backup home directory: /home/zcw_backup_op/20161229130044/ Backup directory: home-zhaocai-release-zhaocai-lib Ok.
把指定的目錄（作爲參數傳遞給腳本）備份到”/home/zcw_backup_op/[DateTime]/“。備份支持多
次操作，不會覆蓋上次備份的內容，而且位於相同備份目錄下。目錄合併，重複文件會以時間信息作爲後綴
自動添加給文件名稱。重複操作會佔用雙倍的磁盤空間。
有些需要重啓後清理日誌的操作，也可以用來備份日誌。效果如下：
[root@iZ28lyaw0o0Z zcw_backup_op]# cd 20161229123917/ [root@iZ28lyaw0o0Z 20161229123917]# ll total 8 drwxr-xr-x 7 root root 4096 Dec 29 12:39 home-zhaocai-release-zhaocai drwxr-xr-x 2 root root 4096 Dec 29 12:41 home-zhaocai-tomcat-back-logs
備份後的文件夾名稱是原文件路徑名稱加上文件名稱。

3 zcw_replace4release-2.0.sh
用法，執行運行。有個條件是，新文件（用來替換舊文件的文件）必須位於當前執行腳本的路徑
下，目錄結構不限制。可以直接處理中文在windows下編寫的.txt說明文檔。依照該說明文檔的替換標準要求完成文件替換。
這個文檔報錯的可能性很大。說明文檔被替換文件不存在（有可能是新增、有可能是路徑錯），當前目錄下不存在新文件。
