Re: [shell-script] permutar: a,b, c -- DICAS ?????

[André Saunite]

Olá,

Dá uma olhada nesse artigo do Júlio pra ver se te ajuda, a saída é um
pouco mais completa do que a do seu exemplo:

http://www.dicas-l.com.br/cantinhodoshell/cantinhodoshell_20080519.php

Exemplo:

$ a={a,b,c}
$ eval echo $a$a$a
aaa aab aac aba abb abc aca acb acc baa bab bac bba bbb bbc bca bcb
bcc caa cab cac cba cbb cbc cca ccb ccc

Abs,
André
