Question

 Write a Perl script that accepts exactly 2 integer arguments where the first argument must be less than the second argument. The script will print a comma separated list of integers starting with the first argument up through the second argument.

 The last printed value should be the second command line argument not be followed by a comma.

 The script should also be able to handle the following errorsituations:

o incorrect number of arguments

o the first argument is not less than the second argument (don’t worry about trying to handle non-integer arguments)

 The script file name must be: intlist.pl

 The script must be located in $HOME/itec400/homework

 Make sure the permissions on the your itec400 directory are 705

 Make sure the permissions on your script are 705

Answer 1

Code:

unless($#ARGV+1==2){
print "error: incorrect number of parameters \n";
print "usage: intlst.pl a b (where a<b)\n";
exit;
}

if($ARGV[0] >= $ARGV[1]){
print "error: incorrect number of parameters \n";
print "usage: intlst.pl a b (where a<b)\n";
exit;
}
else{
$COUNTER=$ARGV[0];
while($COUNTER<= $ARGV[1]){
print $COUNTER;
if($COUNTER < $ARGV[1]){
print ", ";
}
else{
print "\n";
}
$COUNTER = $COUNTER + 1;
}
  
}

Output:

Command Line Arguments 15 Result CPU Time: 0.00 sec(s), Memory: 5284 kilobyte(s) 1, 2, 3, 4, 5

To change permissions of a directory of a file you can use below command:

chmod 705 <directory_name/file_name>

To change script permissions to 705 you can use the command: chmod 705 intlist.pl
