Question

I am having trouble on what exactly to write so I can make the script work, can someone show how to properly do it?

Use the vi editor to enter the following script (name this file testscript):

#!/bin/bash

#script to demonstrate :  reading arguments from a command line &

#                                      interactively from within script

#                                      selection (if… then… else…. fi)

#                                      iteration (for loop)

# USE FILES ENTERED ON THE COMMAND LINE

echo The script you are running is $0

echo The number of lines in file $1 is: 

wc –l $1                                #(note that switch is L and not the number one)

echo The number of words in file $2 is: 

wc –w $2

# READ INPUT FROM THE KEYBOARD AND PERFORM COMPARISON

echo Enter Your Age :

read age

if  [  $age  -le  30  ]

     then

            echo  “you are young”

     else

            echo “you are over 30!”

fi

# USE FOR LOOP TO READ THROUGH FILES PASSED AS ARGUMENTS

for i in $@

do

        echo counting file number $i

done

• to execute the script:
  • chmod a+x testscript
  • . /testscript IFT250 sorted IFT250.dups IFT250.dups2

Dear Student,

As it is clearly not mentioned in the question that whether i need to write a shell script or not so as per my understanding i have written the demo script that print all the arguments passed in the command line.

=============================================================

Script:

=============================================================

#!/bin/bash
#script to demonstrate : reading arguments from a command line &
# interactively from

n=$#

echo "Number of argument passed = $n"

echo -e "Printing all the argument passed"

for i in $*

do

echo "$i"

done

============================================================

Sample Output:

=============================================================

Kindly Check and Verify Thanks...!!!
