macos - OS X : "man" output giving extra characters when redirected

我正在尝试在OS X(El Capitan，v10.11.3)终端(bash shell)中执行简单的输出重定向，并在输出中得到了一堆不需要的字符。在Linux上不会发生这种情况。

例如，如果输入man open > open.txt，则会得到以下信息:

OPEN(1)                   BSD General Commands Manual                  OPEN(1)

NNAAMMEE
     ooppeenn -- open files and directories

SSYYNNOOPPSSIISS
     ooppeenn [--ee] [--tt] [--ff] [--FF] [--WW] [--RR] [--nn] [--gg] [--hh] [--bb _b_u_n_d_l_e___i_d_e_n_t_i_f_i_e_r]
          [--aa _a_p_p_l_i_c_a_t_i_o_n] _f_i_l_e _._._. [----aarrggss _a_r_g_1 _._._.]

DDEESSCCRRIIPPTTIIOONN
     The ooppeenn command opens a file (or a directory or URL), just as if you had
     double-clicked the file's icon. If no application name is specified, the
     default application as determined via LaunchServices is used to open the
     specified files.

     If the file is in the form of a URL, the file will be opened as a URL.

     You can specify one or more file names (or pathnames), which are inter-
     preted relative to the shell or Terminal window's current working direc-
     tory. For example, the following command would open all Word files in the
     current working directory:

     open *.doc

     Opened applications inherit environment variables just as if you had
     launched the application directly through its full path.  This behavior
     was also present in Tiger.

     The options are as follows:

     --aa aapppplliiccaattiioonn
         Specifies the application to use for opening the file

     --bb bbuunnddllee__iinnddeennttiiffiieerr
         Specifies the bundle identifier for the application to use when open-
         ing the file

最佳答案

在OS X的man手册页(man man)中:

TIPS

    [...]

    To  get  a  plain  text  version  of a man page, without backspaces and
    underscores, try

      # man foo | col -b > foo.mantxt

将其应用于您的示例将如下所示:

man open | col -b > open.txt
