Edit /etc/default/grub with your favourite editor, e.g. nano:
sudo nano /etc/default/grub

Find this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Change it to:
GRUB_CMDLINE_LINUX_DEFAULT="text"
Update GRUB:
sudo update-grub

For systems that use systemd
^{This is an additional step for systemd releases, e.g. Ubuntu 15.04, the steps above for grub are still necessary.}
You need to tell systemd to not load the graphical login manager:
sudo systemctl enable multi-user.target --force
sudo systemctl set-default multi-user.target
You will still be able to use X by typing startx after you logged in.

注音符號與漢語拼音對照表
常需要去大陸洽公或已經常駐的朋友，在使用電腦要打字的時候，常會碰到輸入法的問題，若要重新學習最快的方式就是將自己知道的注音符號與漢語拼音做一個對照，例如 ㄅ | B、ㄆ | P 的概念，相信學習一個新的輸入法會很快，Google 也有出一個漢語拼音的輸入法，可以下載來使用。

   

如何透過 concat 將查詢結果資料記錄組合成一串 ?
 

原始資料:

I have been using git to keep two copies of my project in sync, one is my local box, the other the test server. This is an issue which occurs when I log onto our remote development server using ssh;
git clone me@me.mydevbox.com:/home/chris/myproject Initialized empty Git repository in /tmp/myproject/.git/ Password: bash: git-upload-pack: command not found fatal: The remote end hung up unexpectedly fetch-pack from 'me@me.mydevbox.com:/home/chris/myproject' failed.
(the file-names have been changed to protect the guilty... !)
Both boxes run Solaris 10 AMD. I have done some digging, if I add --upload-pack=which git-upload-pack the command works, (and proves that $PATH contains the path to 'git-upload-pack' as per the RTFM solution) but this is really annoying, plus 'git push' doesn't work, because I don't think there is a --unpack= option.
Incidentally, all the git commands work fine from my local box, it is the same version of the software (1.5.4.2), installed on the same NFS mount at /usr/local/bin.
Can anybody help?

Make sure git-upload-pack is on the path from a non-login shell. (On my machine it's in /usr/bin).

To see what your path looks like on the remote machine from a non-login shell, try this:

ssh you@remotemachine echo \$PATH

 

(That works in Bash, Zsh, and tcsh, and probably other shells too.)

If the path it gives back doesn't include the directory that has git-upload-pack, you need to fix it by setting it in .bashrc (for Bash), .zshenv (for Zsh), .cshrc (for tcsh) or equivalent for your shell.

You will need to make this change on the remote machine.

Assume your personal repository is in the directory ~/proj. We first create a new clone of the repository and tell git-daemon that it is meant to be public:
$ git clone --bare ~/proj proj.git $ touch proj.git/git-daemon-export-ok
The resulting directory proj.git contains a "bare" git repository--it is just the contents of the ".git" directory, without any files checked out around it.
Next, copy proj.git to the server where you plan to host the public repository. You can use scp, rsync, or whatever is most convenient.

MySQL 伺服器版本: 5.0.22-log
問題點：寫入 UTF-8編碼中文字進MySQL DB，變成亂碼

修改: adodb/drivers/adodb-mysql.inc.php
兩個連線function _connect _pconnect
function _connect($argHostname, $argUsername, $argPassword, $argDatabasename)
{
if (ADODB_PHPVER >= 0x4300)

$this->forceNewConnect,$this->clientFlags);
else if (ADODB_PHPVER >= 0x4200)
$this->_connectionID = mysql_connect($argHostname,$argUsername,$argPassword,

CentOS 5 的 RPMforge
預設的 RPMforge 軟件庫並不會取代任何 CentOS 的基本套件。過往有些套件的確會這樣做，但它們現在已收錄在一個獨立（rpmforge-extras）、預設被停用的軟件庫。
你可以在 http://packages.sw.be/ 取得所有 RPMforge 套件的清單。

有一堆 thumb_xxxxxxxx.jpg/gif 的圖檔 ,要通通去除 thumb_ 字樣, 想得到的就是一個一個改,  或寫一支 script 批次改
這是很笨的方法 ,
透過 find, sed, xargs, mv 及 管線 | 搭配, 一行指令就解決, 如以下指令.

用sudo时提示"xxx is not in the sudoers file. This incident will be
reported.其中XXX是你的用户名，也就是你的用户名没有权限使用sudo,我们只要修改一下/etc/sudoers文件就行了。下面是修改方
法：
1）进入超级用户模式。也就是输入"su -",系统会让你输入超级用户密码，输入密码后就进入了超级用户模式。（当然，你也可以直接用root用）
2）添加文件的写权限。也就是输入命令"chmod u+w /etc/sudoers"。
3）编辑/etc/sudoers文件。也就是输入命令"vim /etc/sudoers",输入"i"进入编辑模式，找到这一 行："root
ALL=(ALL) ALL"在起下面添加"xxx ALL=(ALL) ALL"(这里的xxx是你的用户名)，然后保存（就是先按一
下Esc键，然后输入":wq"）退出。
4）撤销文件的写权限。也就是输入命令"chmod u-w /etc/sudoers"。
