Extract Script

Esse script é para facilitar a vida de quem usa muito os terminais do Linux. Sempre que você vai extrar um arquivo você tem que:

1- Verificar o formato do arquivo
2- Descobrir o programa que descompacta esse formato
3- Descobrir o processo de descompactar o arquivo
4- Descobrir se quando descompactado ele vai colocar tudo em uma pasta já ou não.
5- Descompactar na forma possível
6- Descobrir o nome da pasta aonde os arquivos extraídos ficaram

Então fiz esse script que resume esses 6 passos em apenas 1:

extract arquivo.qualquer_coisa

ele extrai o arquivo no formato que for e ainda MELHOR: se os arquivos não foram criados com uma pasta raiz, ao invés de ver todos seus arquivos descompactados jogados no seu desktop, ele cria a pasta ANTES e extrai os arquivos lá dentro.

e depois diz aonde ele está ;)

Por enquanto ele suporta apenas tar.gz, tar.bz2, zip e rar... é facilmente extensível e o código está bem comentado para ajudar a todos nessa tarefa
