command to find the size of a file in unix?

I have tried 'ls -l', I was thinking the 4th column was the file size but not sure. Then I tried 'ls -s', but that gave a different result. I also tried 'du' but that only gives size for directory.

maybe you can use this command in your terminal:

find [Your Directory] [Your Options] -exec du -h \;

find has some options like -type(for type of file or directory or l for link). or -iname(for example -iname "a*" for all files or directories that begin with "a"). or -size(for searching with size of files) and etc.

the -exec is another option for find-command. that uses for executing a command on files that are found.

so with find-command you can find your files in any directory that you want and then by -exec you can execute your command like du -h that determines volume of files. just at the end of using -exec don't forget that you must use \;

You may try like this:

ls -l /bin/grep

Output like

-rwxr-xr-x 1 root root 175488 July 18  2014 /bin/grep

Here 175488 is the size of the file

You may also try with:

ls -lh /bin/grep

to get a user friendly size

-h

When used with the -l option, use unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte in order to reduce the number of digits to three or less using base 2 for sizes.

You may also try with:

stat -c "+%s"
