Limitando a 1 login por usuário

No Slackware o /etc/profile determina as variáveis de ambiente do Bash, bem como executa scripts de login.

Hoje precisei restringir 1 login por usuário apenas, e fiz o seguinte:

Se estiver usando o Slackware o arquivo é o /etc/profile, em outras distros pode ser também o /etc/bashrc.

Basta acrescentar a seguinte linha de comando neste arquivo:

if [ `wc -l <(who | fgrep $USER | cut -f1 -d" ") | cut -f1 -d" "` = 2 ];then exit; else :; fi

Pronto!

Bom trabalho.
