实验四shell编程实验（二）班级姓名学号上机时间：年月 任课教师实验教师： 实验成绩 一、实验目的综合Linux常用命令和vi编辑器的使用，熟练掌握shell脚本编程。二、实验注意事项实验室内的实验环境与系统是共用设施（以台计算机上做，这样可以保持连续性。三、实验内容编写一个脚本，求斐波那契数列的前10num1=1num2=1echo-n“$num1+$num2”sum=2for((i=1;i<=8;i++))dotmp=$(expr$num1+$num2)echo-n“+$tmp”((num1=num2))((num2=tmp))sum=$(expr$sum+$tmp)doneecho“=$sum”编写一个脚本，求一个数的逆序。echo-npleaseinputnum:readnumecho-nThenumiswhile[$num-gt0]dosd=$(($num%10))echo-n"$sd"doneecho设计一个Shelluserdata目录，在此目录下再建立5个目录，即user1～user5权限为：读、写、执行；文件所有者所在组的权限为：读、执行（注意：最后删除自己所建立的目录，恢复原样，以便后面同学做此实验）mkdir-m754/home/userdatai=1temp=/home/userdata/userwhile[$i-le5]domkdir-m754$temp$ilet”i=i+1”#done用Shell/home/student/test下,用命令查看test目录内容，最后再删除test目录。mkdir-m777/home/testecho“Inputfilename:”readFILENAMEif[-f“$FILENAME”]thencp$FILENAME/home/testls/home/testcdtestrm$FILENAMEcd.lselseecho”TheFILENAMEisnotaregularfile!”fi‘q’时，才退出执行。参考程序：#!/bin/bash#fileName:first#note:Thisisthefirsttitle#function:inputanexpretionandtheanswer,Iwilltellyourightor# Youcantryitasmanytimesasyoulike.echoHello!@_@echoWelcomtothecalculatetesting!echoYoucaninputanexpretionsuchas2*2or3+1,andinputtheanswerechoIwilltellyouwhetheryouarerightorwrong.echoYoucaninput'q'toexit.echo"Nowlet'sbegin!"number1=0;while["$number1"!="q"]doechoInputthefirstnumber:readnumber1echoInputtheoperatortype:readtypeechoInputthesecondnumber:readnumber2echoInputtheanswer:readyourAnswercase$typein+)myAnswer=`expr$number1+$number2`;;-)myAnswer=`expr$number1-$number2`;;\*)myAnswer=`expr$number1\*$number2`;;/)if[$number2-eq0]thenecho"Sorry!:-("echo"0cannotbethedivisor"continueelsemyAnswer=`expr$number1/$number2`fi;;*)echoError!;;esacif[$myAnswer-eq$yourAnswerthenecho":-)"Congratulations!echoYourareright!echoInput'q'toexitortryagain!elseecho":-("Sorry!echoYouareecho"Therightansweris:"echo"$number1$type$number2=$myAnswer"echoInput'q'toexitortryagain!fi#echoInputthefirstnumber:#read
