判別Linux安裝於EFI Mode或是Legacy Mode?

請用“df –a”指令可以查出SuSE Linux Enterprise Server 是不是裝於EFI Mode

RPM Command

一、基本安裝
rpm -ivh 軟體套件名稱
i 是 install，v(verbose)是顯示，h 是進度以一串 ########### 來表示
二、基本安裝的問題
(1)該軟體已安裝過
rpm -ivh 套件名稱
套件名稱 is already installed..
如果要重新安裝可用--force 指令：
--force 表示強行置換

rpm -ivh --force 套件名稱

(2)沒有相依的套件
rpm -ivh php-imap.x.rpm
failed dependencies:imap is needed by php-imap
如果不管軟體的相依性，可用--nodeps指令強制安裝

rpm -ivh --nodeps php-ldap*.rpm

三、移除套件

rpm -e 套件名稱

四、升級套件

rpm -Uvh 套件名稱

U是upgrade, 表示會把舊的軟體移除再安裝新的，所以不管有沒有安裝過都可以使用rpm -Uvh來安裝軟體
五、更新套件
 rpm -Fvh 套件名稱
-F 選項有個特性：只有已經安裝過的套件才會更新，這點和 rpm -Uvh 中的 U 升級是不同的，因此極適合拿來大量修補套件之用。
六、查詢
rpm -qa | grep mesa
rpm -ql apache
a 是 all，q 是 query 查詢已安裝的套件，grep 是搜尋符合的字串
l 是列出的意思(list)
rpm -qf /usr/bin/neat
查詢 neat 這個指令是從那一個 rpm 套件安裝的。

How to Startup Your Project or folder in Windows 2012 & 2016

In Windows Server 2008 R2, to define an application to be startup automatically for current user, one common way is to create an application shortcut and add it to startup folder. In Windows Server 2012,2016 you might find you can’t find this startup folder any more. 

Here is the steps to find startup folder in Windows Server 2012.

1. WinKey + C to open the charms bar
2. Click “Search”
3. Enter shell:startup and click on the first result returned.

bash script array sample

To declare an array in bash

Declare and an array called array and assign three values:

array=( one two three )

More examples:

files=( "/etc/passwd" "/etc/group" "/etc/hosts" ) limits=( 10, 20, 26, 39, 48)

To print an array use:

printf "%s\n" "${array[@]}" printf "%s\n" "${files[@]}" printf "%s\n" "${limits[@]}"

To Iterate Through Array Values

Use for loop syntax as follows:

for i in "${arrayName[@]}" do : # do whatever on $i done

$i will hold each item in an array. Here is a sample working script:

#!/bin/bash # declare an array called array and define 3 vales array=( one two three ) for i in "${array[@]}" do echo $i done
