Perl check if file exist in directory

You can save yourself some time if you read some books. I'm guessing it took him a very small amount of time to ask these questions, and they are very helpful search results. Don't be a learning style bigot. Adam I think daxim's point is just that the OP's perl questions including this one are all pretty basic and so reading an overview of perl might save some time overall vs asking lots of specific questions whose answers are easily found other ways — GreenGiant.

GreenGiant: I'm quite glad he asked these basic questions, as it means that the answers come up when I search for them. I suspect that might have been the point of asking them in the first place.

I want to create it only if it doesn't exist. I'm using Windows.. I tried -d and -e, it doesn't work Have a look at FAQ In Perl, file existence is checked using file operators which are used for checking if the specified file is present or not in the particular directory or folder is known as checking of file existence using file existence operators such as —X operators where particularly we use —e operator for checking of file presence in the directory or folder in Perl programming language.

In general, we define or check the file existence using file —X operators such as —e operator for checking the presence of file which is provided by the Perl file operators. In this article, we will discuss how to check if the specified file with its filename is present or not in a given directory or folder using the file operators provided by Perl programming language which are the same as logical operators to use in the Perl program.

In this, it has file test operator —X which itself contains various unary file operators for file testing such as file existence, file size, file permissions, etc where these unary operators take the only single argument as the name itself suggests and it will take the filename as an argument with file operator.

There are many different file operators for testing different concepts related to file in Perl. This —e a file test operator is useful as whenever the programmer wants to read a file or write to a file then there is a need of checking file existence then we use this operator which is very important in such case.

Now let us see the simple syntax of how to use file operator for file existence checking in the below section. This operator mostly returns the Booleans value such as true if the file is present and false if the file is not present.
