My Little Nerdy: Why do I use Linux? →
mylittlenerdy:
I use Linux to make a statement.
I make a statement to appreciate the beauty of open-source software. I make a statement about my love of lifelong learning. I make a statement about frugality. I make more than just a statement. I make an invitation.
Open-source software makes the world go…

ubuntu/debian 修改默认shell
ubuntu 从 6.10 Edgy 开始,将/bin/sh链接到了/bin/dash而不是传统的/bin/bash
dash是不同于bash的shell,它的速度更快,但功能要比bash少很多,语法严格遵守POSIX标准。dash更适合执行脚本,而不是交互操作。
(dash和bash的区别可以看这一篇博客:http://www.igigo.net/page/2)
但是很多脚本都不是完全兼容POSIX标准的,而且执行某些操作(例如安装配置OpenVZ)会需要将默认的shell由dash改成bash。
方法一:
$ sudo ln -sf /bin/bash /bin/sh
方法二:
$ sudo dpkg-reconfigure dash 然后选NO
将dash恢复成默认shell,同样执行这个命令,然后选YES

vim 大小寫轉換
大小寫轉換:gu/gU
很形象:gu轉小寫,gU轉大寫
.
例如,全文轉小寫只需要三個步驟:gg gu G
三個步驟的含義是:
gg => 光標移動到第一行
gu => 轉小寫的命令,gu需要指定范圍
G => 到文件結束

FreeBSD 安裝 sudo
# cd /usr/ports/security/sudo
# make install clean

%wheel ALL=(ALL) ALL (允許wheel組的用戶使用sudo)
或 %wheel ALL=(ALL) NOPASSWD: ALL(允許wheel組的用戶使用sudo而不需要輸入密碼)
或 tux ALL=(ALL) NOPASSWD:ALL(允許用戶tux使用sudo且不需要輸入密碼)
保存并退出。
FreeBSD 安装 VIM

Red Hat 和 ubuntu 服务操作对比
启动服务:service httpd start => /etc/init.d/apache start
停止服务:service httpd stop => /etc/init.d/apache stop
让服务随系统启动自动运行:chkconfig httpd on => update-rc.d apache defaults
取消服务随系统启动自动运行:chkconfig httpd off => update-rc.d apache purge(有点问题,请查看man手册)

Linux安装完成之后要做的事
1. 安装vim,修改.vimrc
2. 更新系统,重启,安装驱动程序,再重启
3. 安装字体,中文字体DejaVuSansYuanTi。地址:http://forum.ubuntu.org.cn/viewtopic.php?f=8&t=110509 && http://code.google.com/p/qinsdisk/downloads/list
4. (ubuntu)安装版权受限软体包。
5. ubuntu官方源速度不错,ping了一下显示师sohu的镜像,喜欢163源的朋友可以换成163的。方法很简单:在Ubuntu Software Center的菜单里找到Software Sources……以前在系统设置里有的,12.04之后需要在软体中心里找。
