ls command displays file size in number of bytes by default. To get a more human readable output, -h option can be used, which translates bytes into KB, MB, GB and etc.

How do I check the size of a file in Linux?

Using the ls Command

1. –l – displays a list of files and directories in long format and shows the sizes in bytes.
2. –h – scales file sizes and directory sizes into KB, MB, GB, or TB when the file or directory size is larger than 1024 bytes.
3. –s – displays a list of the files and directories and shows the sizes in blocks.

How do I determine file size in bytes?

Step 2: Multiply total number of pixels by the bit depth of the detector (16 bit, 14 bit etc.) to get the total number of bits of data. Step 3: Dividing the total number of bits by 8 equals the file size in bytes. Step 4: Divide the number of bytes by 1024 to get the file size in kilobytes.
