PERL chdir function

What does the chdir function do in PERL? Simple! It changes the directory you are in!

Here is an example of how you would use the chdir function in PERL:

#First, we open our main directory
opendir(DIR,'test');

#Then we navigate to a subdirectory
chdir 'subtest';

#Now we would be in the 'subtest' folder or directory
#We can navigate back up to the 'test' folder or directory
chdir '..';

The ".." in above example tells PERL to navigate to the folder or directory directly above our current folder or directory.
