Shell Script ~/.bash_profile

Olá, eu tenho uma dúvida em relação á configuração do mongodb. Eu uso o Xubuntu 16.04.

Para configurar o PATH, escrevi assim:

nano ~/.bash_profile

export PATH=$PATH:/home/camilabd/Documentos/mongodbcamila/mongolinux/bin

Depois entrei na pasta bin

camilabd@camilabd-Inspiron-5420:~/Documentos/mongodbcamila/mongolinux/bin$    ./mongod --dbpath /home/camilabd/Documentos/mongodbcamila/mongolinux/data/db

Saiu assim:

Lembrando que eu já tenho as pastas criadas dentro da pasta 'data/db'

Alguém está disposto a me ajudar? xD
