atualizar conteúdo variável

estou editando o arquivo de script do ponto de montagem da rede. Quando a variável é montada, ela contém informações, mas quando é desmontada aparece vazia, e se o script pedir para montar, o conteúdo da variável não é atualizado.

VARIABLE=$(df -h | awk '{print $1}'| grep //user@IP/path/user)

Quando desmontado: echo $VARIABLEvazio, se eu montar com o comando:

open smb://user:passwd@IP/path/user

e digite df -h | awk '{print $1}' | grep //user@IP/path/user parece //user@IP/path/user , mas se eu der o comando de verificação, echo $VARIABLEparece vazio

Alguém pode me ajudar?

Obrigado!!! Eu realmente sei que a variável é dinâmica era o problema. Consegui gerar outra chamada de variável CHECK, meu código não está bonito, queria que voltasse para verificar se está montado, para diminuir linhas de código. Siga o meu script de shell de código
