Script simples para procurar e remover ou exibir o path de um arquivo ou diretório.
O script é simples
rmr_init [-f | -d] directory [directory | file]
rmr_init [-f | -d] [-e | -r] directory [directory | file]
-e show the path of file or directory
-r remove the file or directory
-f set the type to regular file
-d set the type to directory
Já existe o find para fazer a mesma coisa, pesquisar e remover um diretório ou arquivo, mas para efeito de aprendizagem resolvi fazê-lo
