写一个脚本文件checkuser,该脚本运行时带一个用户名作为参数,具体要求如下:
1)如果命令行格式不符合要求,应有错误提示信息;
2)在/etc/passwd文件中查找是否有该用户,
如有,则输出“Found in the /etc/passwd file.”
否则,输出“No such on our system”
-Write a script file checkuser, the script run-time with a user name as a parameter, and specific requirements are as follows: 1) If the command-line format does not meet the requirements, there should be error message 2) in/etc/passwd file to check if there were any users, and if so, then the output " Found in the/etc/passwd file.

arm9的bootloader,适合通用2410x平台
vivi.pal(20051228)支持tv输出和vga输出,vclk为26.25mhz
vivi(20060330)支持vga输出和tv输出,vclk为25mhz
以上两个vivi均编译自vivi-br-release(20051228).tar.gz
在两个不同vivi间切换的方法是在源文件“/include/platform/smdk2410.h”中打开或者取消对PAL640480宏的定义:
#define PAL640480
默认该句是注释掉的,编译得到的vivi的vclk为25mhz
ch7005手册中要求640x480的pal输出时vclk为26.25mhz,但实践中发现并不需要完全等与这个频率,有时候vivi(20051228)的pal效果更好,具体使用哪个参数用户可以多比较尝试,也可以尝试修改成其他的频率。-arm9 Bootloader, Definitive 2410 x suitable platform vivi.pal (20051228) support tv vga output and losers that vclk to 26.25mhz 14:57 (20060330) support tv vga output and exports, vclk for more than two 25mhz were compiled from 14:57 14:57- br-release (20 051,228). tar.gz 14:57 in the two different ways of switching between the source document "/ incl. ude/platform/smdk2410.h "open or cancel right PAL64048 0-definition :# define default PAL640480 comment out of the sentence.
