2、寫腳本if1，測試其功能。 echo -n word 1: read word1echo -n word 2: read word2if test $word1 = $word2 then echo Matchfiecho End of program.編寫腳本chkargs，測試其功能if test $# -eq 0 then echo You must supply at least one argument. exit 1fiecho Program running.編寫腳本if2，測試其功能if test $# -eq 0 then echo You must supply at le

3、ast one argument. exit 1fiif test -f $1 then echo $1 is a regular file in the working directory else echo $1 is NOT a regular file in the working directoryfi編寫腳本if3，測試其功能echo -n word 1: read word1echo -n word 2: read word2echo -n word 3: read word3if $word1 = $word2 -a $word2 = $word3 then echo Matc

4、h: words 1, 2, & 3 elif $word1 = $word2 then echo Match: words 1 & 2 elif $word1 = $word3 then echo Match: words 1 & 3 elif $word2 = $word3 then echo Match: words 2 & 3 else echo No matchfi編寫smartzip 腳本，測試其功能#!/bin/bashftype=file $1case $ftype in$1: Zip archive*)unzip $1 ;$1: gzip compressed*)gunzip

5、 $1 ;$1: bzip2 compressed*)bunzip2 $1 ;*) echo File $1 can not be uncompressed with smartzip;esac編寫腳本dirfiles，測試其功能。for i in *do if -d $i then echo $i fidone編寫腳本until1，測試其功能。用while改寫之。secretname=jennyname=nonameecho Try to guess the secret name!echountil $name = $secretname /while改寫位 while “$name” !

6、= “$secretname” ,其他地方不變do echo -n Your guess: read namedoneecho Very good.編寫腳本brk,測試其功能。for index in 1 2 3 4 5 6 7 8 9 10 do if $index -le 3 ; then echo continue continue fi# echo $index# if $index -ge 8 ; then echo break break fidone編寫腳本command_menu，測試其功能。echo -e n COMMAND MENUnecho a. Current date

7、 and timeecho b. Users currently logged inecho c. Name of the working directoryecho -e d. Contents of the working directorynecho -n Enter a, b, c, or d: read answerechocase $answer in a) date; b) who; c) pwd; d) ls; *) echo There is no selection: $answer;esac編寫腳本demo_shift，測試其功能。echo arg1= $1 arg2=

8、$2 arg3= $3shiftecho arg1= $1 arg2= $2 arg3= $3shiftecho arg1= $1 arg2= $2 arg3= $3shiftecho arg1= $1 arg2= $2 arg3= $3shift編寫shell腳本sum1，求命令行上整數(shù)和。即：$./sum1 5 12 4 6，給出和的結(jié)果。sum=0for i in $*do let sum=sum+idoneecho “和是:$sum”編寫腳本filetest，判斷當前目錄下所有文件類型，如果是普通文件，顯示文件內(nèi)容；如果是目錄文件，顯示目錄列表；如果是大小為0的文件，刪除它；否則，顯示

9、“sorry， The file is not recognized!”for i in *do if -d $i then ls $ielif -f $i then if -s $i then cat $ielse rm $i fielse echo n “sorry,the file cant be recognized”fidone編寫shell腳本user，判斷當前登錄用戶是否為“學(xué)號命名”的用戶，是，提示：hello “學(xué)號用戶”,welcome!，否，提示“you should login using your username! ”Read nameIf $USER = $nam

10、e Then echo “hello $USER”else echo “you should login using your username!”fi編寫shell腳本menu，使用shell編寫一個菜單，分別實現(xiàn)列出以下內(nèi)容：（1）顯示目錄內(nèi)容、（2）切換目錄、（3）創(chuàng)建文件、（4）編輯文件、（5）刪除文件的功能。在此例中將用到循環(huán)語句、分支語句和輸入輸出語句。Echo “a.display the directory”Echo “b.change the directory”Echo “c.create a file”Echo “d.delete the file”Echo “if yo

11、u input nothing,you will exit”Read itemUntil -z $item Do Case $item in Echo “input the directory”Read direLs $dire;Echo “input the directory you want go into”Read direCd $dire;Echo “input the file you want to create”Read fTouch $f;Echo “input the file you want to delete”Read fRm $f;EsacEcho “a.displ

12、ay the directory”Echo “b.change the directory”Echo “c.create a file”Echo “d.delete the file”Echo “if you input nothing,you will exit”Read itemdone編寫腳本，實現(xiàn)一個簡單計算器。+ addition- subtractionx multiplication/ division腳本執(zhí)行形式：$ ./cal.sh 21 / 3Let l=$1 /最簡單的一種形式，而且還特別高效Echo $1;第二種方式：Re=”+ - * /”For var in $reDo If $var = “*” ThenNum2=$1#* Num1=$1%* Else Num2=$1#*$var Num1=$1
