Here’s a video that looks at loading datasets in Python. These methods are useful when you have already opened the file to read the data. Size = file_object.tell() # Get the cursor position, which is the size of the file Here is some sample code that shows the two methods in use on a file object: def get_file_size(file_object):įile_ek(0, 2) # Move the cursor to the end of the file Call the tell() method to get the current cursor location, which represents the total size in bytes.Move the cursor to the end of the file using the seek() method.To find the size of a file object, you can use these methods together in two steps: The file pointer represents the current position in the file from where the next read or write operation can take place. There are two common techniques to handle operations on file-like objects in Python: the seek() and tell() methods.īoth methods manipulate the file pointer or cursor. How to Use Seek and Tell to Check File Size in Python If you’re running the sample code, replace the string with the absolute path of your file. # Replace 'your_file_path' with the actual file path You provide the file path as the argument. The getsize function returns the file size in bytes directly. The os.path.getsize() function is one of the simplest ways to get the file size in Python. Two primary functions provide information about sizes: The Python os module provides various functions to interact with the operating system and work with files and directories. How to Use the os Module to Get File Size How to Use Seek and Tell to Check File Size in Python.How to Use the pathlib Module To Get File Sizes in Python.How to Use the os Module to Get File Size.The logic of -size -2k is any file which size rounded up to the next kilobyte is less than 2. The logic of -size -2048c is any file which size in bytes is less than 2048. The logic of -size 2k means all files with size rounded up to the next kilobyte is 2

The logic of -size 2048c means all files with size in bytes is 2048. Here is the dd command I used to create the files: dd if=/dev/zero of=filename bs=1 count=filesizeinbytes The 'b' suffix always denotes 512-byte blocks and never 1 Kilobyte blocks, which is different to the behavior of -ls.įor demonstration I created files named corresponding to their size in bytes: $ ls -l Bear in mind that the '%k' and '%b' format specifiers of -printf handle sparse files differently. The size does not count indirect blocks, but it does count blocks in sparse files that are not actually allocated. Not sure if it's related to this note (from the find man page - in the size section): Which should be the exact equivalent since 'c' stands for bytes, and in this case it found all the files I was looking for.Īny idea as of why this behavior? I'm probably missing the obvious here. Which according to the man page of find should return everything smaller than 2Kilobytesīut what I noticed is that it missed a number of files, which were between 1 and 2Kb in size.įind /folder_to_search_into/ -type f -size -2048c I just stumbled in an oddity with the find command on Linux, in a nutshell I had the need to find all files smaller than 2Kb in a certain folder, so I issued the command:įind /folder_to_search_into/ -type f -size -2k
