<p>Edilmar, EM TEMPO:<br>
O script abaixo faz o básico.<br>
Lógicamente você tem que se preocupar com outros testes da placa, tipo: se ele queimar, etc.<br>
Aí tem que implementar outros testes, senão corre o risco do script entrar em loop infinito e te causar problemas de uso de processamento.<br>

<strong>Assunto: </strong> RE: [shell-script] Executar script interface<br>
</div>
Olá, Edilmar.<br>
Aqui a Distro é Debian 9.<br>
Não tenho placa wifi aqui, mas segue um exemplo:<br>
Meu comando: /sbin/ifconfig lo<br>
Retorno: lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 (na primeira linha).<br>
<br>
No teu caso, o retorno deve ser algo similar.<br>
<br>
Então, derrubei a placa "lo" aqui e o seguinte script funcionou:<br>
<br>
#!/bin/bash<br>
/sbin/ifconfig lo | grep UP >/dev/null<br>
ret=$?<br>
while [[ $ret -ne 0 ]]<br>
do<br>
echo "Placa lo em estado OFF"<br>
echo "Subindo a placa lo"<br>
/sbin/ifconfig lo up<br>
ret=$?<br>
done<br>
<br>
Tenta aí.<br>
<br>
