Alguém sabe como as findconsultas de pesquisa Unix -name com _?na coluna mais à esquerda se relacionam com Kleene Star conforme definido na Wikipedia ? Como posso realizar as linhas com _?using find?
. : empty string, X : cartesian product
-name \A\B Language A X B
-name \ABC Language A X B X C
-name : name at leafs, builds set of string in language
-name \. V^0 {e, ""} language only of the empty string A with only one leg?
-name \? V^1 V language of single characters
-name \???... V^n language of n character strings, concatenates strings in language
-name \* V^* langauge of \cup_{i\gte0} V^i
a? -name \n V^n like \{n\} in grep with integer?
b? -name \*n (V^*)^n language of n words, word can be empty
-name \*\??... (V^*)^n
-name \?\* V^+ langauge of \cup_{i\gte1} V^i
-name \?\*\??... (V^+)^n language of n words, word must have character
Parece que .é um gráfico Acom apenas uma perna definida com comprimento. grepusa \{n\}para a?, no entanto não consigo encontrar o equivalente com find.
