ack没有做递归grep

Question

ack(grep用Perl编写的工具)找不到找到的文件,grep -r我找不到合适的选项让它工作.以下显示ack未找到目标字符串,该字符串位于子目录中的常规文件中.它在Bash shell(Ubuntu 11.04)上:

100 $ grep -r imbue *
    hel/find:              the  fact that some shells including Bash imbue braces
    ## Note: grep find it as shown in the above.

101 $ ./ack-standalone   imbue  
    ## Note: ack didn't find it as shown in the above.

102 $ ./ack-standalone   --version
    ack 1.96

        perlrun
        perlvar
        xargs

    1 directory, 11 files

来自apt-get软件包安装的ack版本2获得了相同的结果.在上面显示的独立版本(版本1)中.ack -f没有显示,我尝试了-r和*选项,都有相同的结果.

在另一台机器上,Ubuntu 10.04,它就像一个魅力.

如果我选择在所有文件中操作而不管其类型,使用-a开关(我的版本与您的相同),它对我有用:

ack -a imbue *
