Erro usando o comando find [RESOLVIDO]

Quando executo o comando:
[root@host treinamento]# find . -size +500M

Retorna o erro:

find: invalid -size type `M'

Alguém sabe me dizer o que pode estar acontecendo?

Quando executo com:

[root@host treinamento]# find . -size +500000

Funciona.

Executei este comando com "Red Hat Enterprise Linux AS release 4 (Nahant Update 2)"

Olá Alessandro!!!

Os sufixos permitidos para o comando find são:

b (default) - blocos de 512 bytes;
c - bytes;
k - kilobytes;
w - palavra (2 bytes)

Ou seja, seu M está errado pq não existe mesmo!!

Oi Alexandre,

O negócio é que eu olhei o manual do find e lá aparece como possível usar os [cwbkMG]... olha só...

-size n[cwbkMG]
File uses n units of space. The following suffixes can be used:

‘b’ for 512-byte blocks (this is the default if no suffix is used)

‘c’ for bytes

‘w’ for two-byte words

‘k’ for Kilobytes (units of 1024 bytes)

‘M’ for Megabytes (units of 1048576 bytes)

‘G’ for Gigabytes (units of 1073741824 bytes)

The size does not count indirect blocks, but it does count blocks in sparse files that are not actually allocated. Bear
in mind that the ‘%k’ and ‘%b’ format specifiers of -printf handle sparse files differently. The ‘b’ suffix always
denotes 512-byte blocks and never 1 Kilobyte blocks, which is different to the behaviour of -ls.

E, a dúvida surgiu depois de receber uma dica do seguinte site: http://www.dicas-l.com.br/dicas-l/20071001.php

Abraços.
