What others think

In computer science, we measure in units of "powers of two":

one kilobyte is 1024 bytes

one megabyte is 1024*1024 = 1048576 bytes

one gigabyte is 1024*1024*1024 = 1073741824 bytes

Ergo, to find files larger than 1 gigabyte:

find / -type f -size +1073741824c # find files > 1gb

You have one too many -'s:

find / -type -f -size +1000000000c

should be

find / -type f -size +1000000000c

@folengo, I think most people assume that "1 GB" means 2^30 bytes rather than 10^9 bytes. Although there's nothing wrong with 10^9 for 1GB (maybe you make hard drives) Maybe you know that since you used the 'c' unit on the size.

I like to think of it this way:

1K = 2^10 bytes (i.e. 10 bits needed to byte-address 1K),

1M = 2^20 bytes,

1G = 2^30 bytes, etc.

As it should, 'find' allows you to specify any size, but the -size option lets you specify units of base-2 sizes so the command

find / -type f -size +1G

will find files larger than 1,073,741,824 bytes rather than 1,000,000,000 bytes.

You can pipe this to ls to find out how big each file actually is:

find / -type f -size +1G | xargs ls -lh

Great command, but this xargs won't handle spaces in file names.
