Perl | sleep() Function - GeeksforGeeks

sleep() function in Perl is an inbuilt function which is used to delay the execution of the current script for a specified number of seconds or forever if parameter is not specified. The sleep( ) function accepts seconds as a parameter and returns the same on success.

Syntax: sleep(seconds)

Returns: seconds passed to it as parameter, on success

Example 1:

#!/usr/bin/perl -w 
  
# Using localtime() function 
# to print the time 
print scalar localtime(); 
  
# calling the sleep function 
sleep(5); 
  
print "\n"; 
  
print scalar localtime(); 

Output:

Thu Mar 28 06:02:21 2019
Thu Mar 28 06:02:26 2019

Example 2:

#!/usr/bin/perl -w 
  
# Using localtime() function 
# to print the time 
print scalar localtime(); 
  
# Using rand() to generate random delay 
sleep(rand(7)); 
  
print "\n"; 
  
print scalar localtime(); 

Output:

Thu Mar 28 06:02:26 2019
