Problem exporting secret keys

[Ivan Herhandez]

Hello! i have the need to export my secret key in
order to use in other system. Well, when i do 

./gpg -a --export 

it works fine for the public key, but when i to

./gpg -a --export-secret-keys my_name

it says:

gpg: my_name: user not found: secret key not available
gpg: WARNING: nothing exported

Well... i tried using my complete name, my coment, my
mail... where can i find my username?????

A ./gpg --fingerprint command shows this data:

"Ivan Hernandez (El inbatible)
<ivan.hernandez@globalsis.com.ar>"

where is my username???

thanks in advance.
Ivan Hernandez
