I have a relative path
$base_path = "input/myMock.TGZ";
myMock.TGZ is the file name located in input folder.
The filename can change. But the path is always stored in $base_path.
I need to check if the file exists in $base_path.
Test whether something exists at given path using the
-efile-test operator.However, this test is probably broader than you intend. The code above will generate output if a plain file exists at that path, but it will also fire for a directory, a named pipe, a symlink, or a more exotic possibility. See the documentation for details.
Given the extension of
.TGZin your question, it seems that you expect a plain file rather than the alternatives. The-ffile-test operator asks whether a path leads to a plain file.The perlfunc documentation covers the long list of Perl’s file-test operators that covers many situations you will encounter in practice.
