The command du allows you to find out the disk space used by a file:
# du -csh * 1.2M CMakeFiles 4.0K CMakeLists.txt 8.0K CMakeTmp 4.0K browser.cpp 4.0K browser.h 4.0K main.cpp 1.3M total
The difference to ls -l is that you can get a total and that directories are also shown with the correct size.
# ls -ld CMakeFiles/ drwxr-xr-x 7 root root 4096 Feb 14 10:12 CMakeFiles/ # du -csh CMakeFiles/ 1.2M CMakeFiles/ 1.2M total
be aware
tweedleburg:~ # du -sch archiv 0 archiv 0 total tweedleburg:~ # du -sch archiv/ 80G archiv/ 80G total tweedleburg:~ # ll archiv lrwxrwxrwx 1 root root 22 Jul 15 13:09 archiv -> /mnt/barracuda/archiv/
