Perl | redo operator

redo operator in Perl restarts from the given label without evaluating the conditional statement. Once redo is called then no further statements will execute in that block. Even a continue block, if present, will not be executed after the redo call. If a Label is given with the redo operator then the execution will start from the loop specified by the Label.

Syntax: redo Label

Returns:
No Value

Example 1:

#!/usr/bin/perl -w

$a = 1;

# Assigning label to loop
GFG: {
   $a = $a + 5;
   redo GFG if ($a < 10);
}

# Printing the value
print ($a);

Output:

11

Example 2 (Redoing a loop):

#!/usr/bin/perl -w

$a = 1;

# Assigning label to loop
$count = 1;
GFG: while($count < 10) {
   $a = $a + 5;
   $count++;
   redo GFG if ($a < 100);
}

# Printing the value
print ("$a $count");

Output:

101 21
