## Overview
The **`rename()` method** renames a file in Perl.

## Syntax
```perl
rename(currentName, newName)
```
## Parameters
* **`currentName`**: This is the current file's name.
* **`newName`**: This is the new name we want to give the file.

## Return value
The value returned is either `1` or `0`. `1` is returned if the process was successful, and `0` is returned if it was unsuccessful.
## Code example

# rename files and print results
print rename("main.perl", "app.perl");
print "\n";
print rename("test.txt", "newtest.txt");

## Explanation
* We have already created our application code file `main.perl`.
* In line 2, we try renaming our `main.perl` using the `rename()` function and print the result. This is successful. Hence, `1` is returned.
* In line 3, we try renaming a file we did not create. This returns `0` because it was not successful.
