１：修改ｌｉｎｕｘ系统声音命令（重启也生效）
amixer -c 0 sset 'Master',0 【声音】%,100% unmute
amixer cset numid=13 0--31

修改声音需要找到master接口

如果没有在 /etc/asound.conf 加defaults.pcm.card 1 defaults.pcm.device 0 defaults.ctl.card 1
amixer controls 查看接口
amixer contents 查看接口详细内容
amixer cset numid=接口id 值
amixer cget numid=接口id

２：修改系统的分辨率（重启失效）
Xrandr -s 宽x高

３：安装ｍｙｓｑｌ时自动填密码
sudo debconf-set-selections <<< 'mysql-server mysql-server/root_password password 123456'
sudo debconf-set-selections <<< 'mysql-server mysql-server/root_password_again password 123456'

４：ｓｕｄｏ的时候自动填密码
echo -e "1111\n"|sudo -S ls -l -e　特殊字符　　－ｓ使用脚本

６：在ｃ／ｃ＋＋中使用ｓｕｄｏ自动填密码
echo "1111"|sudo -S　ls

５：安装软件时候自动按一个Ｙ
echo "y"|sudo apt-get install kdiff3

6 AWK 以｜分割　取第２，５
awk -F '|' '{print $2,%5}'

firefox www.oschina.net -height 800 -width 600

ps -aux |grep -E "led_play|LED_Upgrade"|sed '/sh -c/d'|sed '/grep/d'|sed '1s/^/USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND\n/'|awk -F ' ' '{print $1,$2,$3}'

自动启动sudo update-rc.d test defaults 95
sudo update-rc.d -f test remove

REQUEST php不管任何方式传递的数据都获取

进行附近设备扫描
sudo apt-get install aircrack-ng
sudo airmon-ng start wlan0

core文件生成
ulimit -c unlimited

//按照某个字段排序名显示20行
select * from maclist order by `Time` desc limit 0,20；
