Forfiles

http://technet.microsoft.com/en-us/library/cc753551(WS.10).aspx

Syntax

forfiles [/p Path] [/m SearchMask] [/s] [/c Command] [/d[{+ | -}] [{MM/DD/YYYY | DD}]]

Parameters

/p Path

指定您要在其上開始搜尋的 Path。預設資料夾為目前的工作目錄，您可以透過輸入句點 (.) 來指定。

/m SearchMask

依據 SearchMask 來搜尋檔案。預設的 SearchMask 為 *.*。

/s

指示 forfiles 在子目錄中搜尋。

/c Command

在每個檔案上執行指定的 Command。您必須將帶有空格的命令字串包含在引號中。預設的 Command 為 "cmd /c echo @file"。

/d[{+ | -}] [{MM/DD/YYYY | DD}]

選取日期大於等於 (+) 或小於等於 (-) 指定日期的檔案，其中 MM/DD/YYYY 是指定的日期，而 DD 是目前日期減去 DD 天。如果您未指定 + 或 -，則會使用 +。DD 的有效範圍為 0 - 32768。

/?

在命令提示字元上顯示說明。

Remarks

• Forfiles 最常使用於批次檔案中。

• Forfiles /s 與 dir /s 類似。

• 下列表格列出了您可以在 /cCommand 命令字串中使用的變數。

變數 描述

@file 檔案名稱

@fname 不含副檔名的檔案名稱

@ext 副檔名

@path 檔案的完整路徑

@relpath 檔案的相對路徑

@isdir 如果檔案類型是目錄，則判斷值是 TRUE，否則判斷值是 FALSE。

@fsize 檔案大小 (以位元組為單位)

@fdate 檔案上的上次修改日期戳記

@ftime 檔案上的上次修改時間戳記

• 使用 forfiles，您可以在多個檔案上執行命令，或將引數傳送到多個檔案。例如，您可以在樹狀目錄中帶有 *.txt 副檔名的所有檔案上執行 TYPE 命令。或者，您可以執行 C: 磁碟機上的每個批次檔案 (*.bat)，以檔案名稱 Myinput.txt 作為第一個引數。

• 使用 forfiles，您可以執行下列任何一項動作：

• 使用 /d 按絕對或相對日期選取檔案。

• 使用變數，例如 @fsize (檔案大小) 及 @fdate (檔案日期)，來建立檔案的保存樹狀目錄。

• 使用 @isdir 變數以從目錄中區分檔案。

• 藉由在命令列中包含特殊字元，及使用十六進位字碼 0xHH 包圍字元，來格式化輸出。

• Forfiles 藉由執行工具 (設計用於僅處理單一檔案)上的 recurse subdirectories 旗標來運作。

Linux -- 檔案系統樹狀標準

• 根目錄 (/)：為整個檔案系統樹狀結構的根，也就是整個檔案系統的根目錄。
• /bin： 此目錄中存放著許多的 Binary 執行檔案，為一般及啟動時常常會使用到的檔案，例如 ls、cp、rm ...等指令。
• /sbin：此目錄中存放著許多的 System Binary 執行檔案，為系統管理時常常會使用到的檔案，例如 shutdown、fsck、quotacheck...等指令。
• /etc：此為 Linux 系統中相當重要得目錄，大部份的設定檔都存放於此，例如檔案系統掛載設定檔 /etc/fstab、IPTables 防火牆設定檔 /etc/sysconfig/iptables...等。
• /lib：存放 Linux 系統中各種共用的 Library 函式庫檔案，類似於 Windows 作業系統的 DLL 動態連結函式庫一樣的功能。
• /dev：Linux 系統是以 Everything is Files 的觀念來進行管理 Device 硬體裝置，因此硬體設備及週邊設備也不例外，此目錄中存放著所偵測到的相關硬體檔案，例如 光碟機為 /dev/cdrom、SCSI 硬碟為 /dev/sda...等，為相容舊版系統而存在。
• /sys：存放 System-Device 相關資訊 (由 RHEL 4 開始才有此資料夾)，如 PnP...等，會將偵測到的 Device 資訊回寫至 /dev 對應的檔案內以相容舊版，所以舉例來說當主機插入 USB 隨身碟時會同時建立 /sys/block/sdb 以及回寫至 /dev/sdb 內。
• /selinux：存放 Linux 增強安全性機制 SELinux (Security Enhanced Linux) 相關檔案。
• /var 具備 Variable 也就是變動特性的檔案將存放於此，例如 系統的各式日誌檔案 /var/log、使用者電子信箱 /var/mail、正在執行的執行序 /var/run/*.pid ...等。
• /srv：存放相關的 Server-data。(由 RHEL 4 開始才有此資料夾)
• /usr：Linux 系統中大部份的 安裝套件及相關應用程序 都存放於此，例如其它網路服務的執行程序 /usr/sbin、核心原始碼檔案 /usr/src...等，類似於 Windows 作業系統的Program Files 資料夾。
• /opt：Optional 通常非預設安裝的套件會安裝於此，例如 Oracle 資料庫...等。
• /lost+found： 在每個獨立的掛載點內都會有此資料夾，當 Linux 系統不正常關機時相關資料便會暫存於此。
• /mnt： 用於 臨時掛載的目錄，通常會手動執行將外接設備掛載於此。(Kernel 2.4.x 使用)
• /media： 若 RunLevel 為 5 也就是進入圖形介面時 (由 RHEL 4 開始才有此資料夾)，若主機有插入 USB 或其它外接設備時則會自動掛載於此目錄上 (不需手動掛載)。(Kernel 2.6.x 使用)
• /misc、/net： 用於 autofs 自動掛載時所使用的資料夾，例如 Linux 主機成為 LDAP、NIS Client 時便會將相關資料夾自動掛載於此，類似於 Windwos 作業系統中網路芳鄰的概念。
• /tmp： 暫存資料夾，存放暫時性的資料夾及檔案，通常 Linux 系統重新啟動或關機以及排程會自動清空此資料夾內容。
• /proc： Linux 系統中目前所執行的 執行序 Process 即存放於此資料夾，當該執行序停止執行則位於此資料夾中的 Process ID 或檔案將消失 (事實上此資料夾就是 Memory 中的暫存資料)，至於有些檔案的大小為何是 0？ 例如 meminfo、cpuinfo 則只是為了要達成 Everything is Files 的觀念而以，但仍可查看及檔案內容。
• /boot： 存放 Linux 系統開機時相關引導檔案，例如 Boot Loader 設定檔 /boot/grub/grub.conf、初始化映像檔 .img...等。
• /home： 所有 一般使用者帳號的家目錄，例如 使用者帳號 weithenn 的家目錄為 /home/weithenn。
• /root： Linux 系統超級管理者的家目錄。

Connecting to the Console Port with Mac OS X

Connecting to the Console Port with Mac OS X

This procedure describes how to connect a Mac OS X system USB port to the console using the built-in OS X Terminal utility.

Step 1 Use the Finder to go to Applications > Utilities > Terminal.

Step 2 Connect the OS X USB port to the router.

Step 3 Enter the following commands to find the OS X USB port number:

macbook:user$ cd /dev
macbook:user$ ls -ltr /dev/*usb*
crw-rw-rw-  1 root    wheel       9,  66 Apr  1 16:46 tty.usbmodem1a21
DT-macbook:dev user$

Step 4 Connect to the USB port with the following command followed by the router USB port speed:

macbook:user$ screen /dev/tty.usbmodem1a21 9600
To Disconnect the OS X USB Console from the Terminal Window

Enter Ctrl+A followed by Ctrl+\

MRBS -- the steps of installation

cp -r web /var/www/mrbs
配置timezone。找到config.inc.php文件。去掉$timezone = "XXXXXXX"的註釋，並修改成$timezone = "Asia/Taipei"。
配置數據庫。還是config.inc.php文件。修改以下參數，分別對應數據庫類型、主機、數據庫實例、用戶名、密碼、表前綴。例如：
$dbsys = "mysql";
$db_host = "localhost";
$db_database = "mrbs";
$db_login = "root";
$db_password = 'xxxxxxxx';
$db_tbl_prefix = "mrbs_";
配置用戶授權類型。
在config.inc.php文件的尾部添加$auth["type"]="db";

@配置mysql數據庫
mysql -uroot -p111111
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '111111' WITH GRANT OPTION;
mysql>FLUSH PRIVILEGES;
mysql>CREATE DATABASE `mrbs` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
退出數據庫，返回到mrbs-1.4.6目錄
mysql -uroot -p111111 mrbs < tables.my.sql
mysql -uroot -p111111 mrbs < sample-data.sql
全部部署完畢。

How do I retrieve the event logs that have been logged in the past 10 minutes?

You need to use the SUB function to subtract 10 minutes from the current UTC timestamp returned by the SYSTEM_TIMESTAMP function, and convert this timestamp to local time using the TO_LOCALTIME function:

SELECT *
FROM System
WHERE TimeGenerated >= TO_LOCALTIME( SUB( SYSTEM_TIMESTAMP(), TIMESTAMP( '10', 'mm' ) ) )

How to move user Databases

The procedures in this topic require the Logic name of the database files. To obtain the name, query the name column in the "sys.master_files" catalog view.
>select * from sys.master_files

To move a data or log file as part of a planned relocation, follow these steps:

1. Run the following statement.
>ALTER DATABASE database_name SET OFFLINE;

2. Move the file or files to the new location.

3. For each file moved, run the following statement.
>ALTER DATABASE database_name MODIFY FILE ( NAME = logical_name, FILENAME = 'new_path\os_file_name' );

4. Run the following statement.
>ALTER DATABASE database_name SET ONLINE;

5. Verify the file change by running the following query.
>SELECT name, physical_name AS CurrentLocation, state_desc FROM sys.master_files
WHERE database_id = DB_ID(N'<database_name>');

mbralign options of NetApp

mbralign --sparse /vmfs/volume/"Datastore"/"Virtual Machine"/"Virtual Machine"-flat.vmdk

Options:

   --sparse                 The resulting file will be sparse.  This option is designed for NetApp NFS based datastor                            es.

   --force                  The default behavior is to skip properly aligned disks.

                            The --force option can be used to override this. (Useful for migrating and making sparse)                            .

   --bs=n                   Use n as the block size (specified in kB).  n must be one of (8, 16, 32, 64, 128, 1024).                             The default is 8.

   --preview                Show what would be done, then exit.  No changes are madeto the file.

   --quiet                  Only print warnings and errors (no other status isprinted to screen).

   --debug                  Print debug comments.

   --help                   Print usage.

   --thereAreNoVmSnapshots  Suppress the warning message about snapshots and answer YES to the question of whether to                            continue.

• It copies one on one your files to allmost any destination you want
• You don't need Yadis! Backup to access the backed-up files
• The marked folders are backed-up real-time (no scheduling needed!). You make a change? Yadis! Backup makes a backup
• When your backup destination isn't available, Yadis! remembers the changes you have made. Whenever the location becomes available Yadis! starts backing up the changes.

' This program scans all users in the AD,for users whose passwords have either
' already expired or will expire within DAYS_FOR_EMAIL days.
'
' An email is sent, using CDO, via the SMTP server specified as SMTP_SERVER to the
' user to tell them to change their password. You should change strFrom to match
' the email address of the administrator responsible for password changes.
'
' You will, at a minimum, need to change the SMTP_SERVER,  and the STRFROM constants.
' If you run this on an Exchange server, then SMTP_SERVER can
' be "127.0.0.1" - and it may be either an ip address or a resolvable name.
