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
- –l – displays a list of files and directories in long format and shows the sizes in bytes.
- –h – scales file sizes and directory sizes into KB, MB, GB, or TB when the file or directory size is larger than 1024 bytes.
- –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.
How do I check the size of a file in Unix?
Getting file size using find command
find “/etc/passwd” -printf “%s” find “/etc/passwd” -printf “%sn” fileName=”/etc/hosts” mysize=$(find “$fileName” -printf “%s”) printf “File %s size = %dn” $fileName $mysize echo “${fileName} size is ${mysize} bytes.”
How can I see the size of a folder?
Go to Windows Explorer and right-click on the file, folder or drive that you’re investigating. From the menu that appears, go to Properties. This will show you the total file/drive size. A folder will show you the size in writing, a drive will show you a pie chart to make it easier to see.
What is the size of Linux?

What is the formula for image size?
FILE SIZE is calculated by multiplying the surface area of a document (height x width) to be scanned by the bit depth and the dpi2. Because image file size is represented in bytes, which are made up of 8 bits, divide this figure by 8.
How many bytes is a file?
There are 1,024 bytes in a kilobyte and 1,024 kilobytes in a megabyte, thus a 1 kb document would contain 1,024 bytes of data or 1,024 characters of text and other programming information that describes the document’s formatting and other characteristics so it can be opened and used by a software application such as a …
How do I copy a file in Linux?
The Linux cp command is used for copying files and directories to another location. To copy a file, specify “cp” followed by the name of a file to copy. Then, state the location at which the new file should appear. The new file does not need to have the same name as the one you are copying.
What does df command do in Linux?
df (abbreviation for disk free) is a standard Unix command used to display the amount of available disk space for file systems on which the invoking user has appropriate read access. df is typically implemented using the statfs or statvfs system calls.
