In this tutorial, I will be using an inbuilt Perl function called FILE HANDLE to open and read files. Perl has third party modules which facilitates performing some tasks.

But for some reason the values Perl is getting are not the same as the data in the file. If an offset is specified, the bytes that are read are placed into the buffer starting at the specified offset. With ActivePerl on Windows system, r (0x0D) is automatically removed from the input. Perl: Reading binary file one byte at a time Ask Question 7 I'm writing a tool that needs to read a binary file one byte at a time, process each byte, and potentially take some action depending on the processed value. Description This function reads, or attempts to read, LENGTH number of bytes from the file associated with FILEHANDLE into BUFFER. It is obvious that you may need to perform a task which requires working with files. The syntax to declare open () function in Perl is as follows: Open (FileHandle, mode, filepath) where FileHandle is the variable associated with the file that is to be opened, mode specifies if the file is opened for reading, writing or appending and filepath specifies the path to the location of the file that is to be opened. There is a special variable, /, which stores the input record separator. Submitted by Godwill Tetah, on December 12, 2020
