There's one thing that always annoyed me about globbing: How can I match *all* files in a directory? Not just regular files but hidden dotfiles as well, but obviously not the special . and .. directories. It often happens that I want to move/copy all files from one directory to another but then it leave behind .htaccess files and the like. |

I always just say * .??* to mean all files. Of course the ?? after the dot is to keep it from matching . and .. |

But that fails to match dotfiles with less than three characters. |

I use ".[0-9A-Za-z]*" to match the hidden files and directories. In my $HOME, I have none with strange symbols after the first dot, so that pattern matches well enough for me. |

Quoting:I use ".[0-9A-Za-z]*" to match the hidden files and directories. What if I drop a file called ".?ó??"? :) I usually use this one: .[^.]* |

Argh. There are supposed to be funny characters in my example filename, not question marks. Who wrote this forum software?? ;P |

Ha! I just found the 'dotglob' option. run "shopt -s dotglob" and now * will match dotfiles but not . and .. |

Dot-question and dot-dot are dangerous, because they will take you up instead of down. @jezuch: The forum began mis-behaving after the blackout recovery. |
