如何在无需确认的情况下减少打开二进制文件的数量？

我有几个日志文件包含一些不可显示的字符（由于请求上的二进制签名）。

每次我用 less 打开它们时，我都会被问到：

$ less /var/log/file.log       
"/var/log/file.log" may be a binary file.  See it anyway?

如何使用命令行选项或配置来跳过这一步？

使用-f选项：

-f or --force
              Forces non-regular files to be opened.  (A non-regular file is a directory or
              a device special file.)  Also suppresses the warning message  when  a  binary
              file  is  opened.   By  default,  less will refuse to open non-regular files.
              Note that some operating systems will not allow directories to be read,  even
              if -f is set.

您可以将此选项添加到LESS.bashrc 中的环境变量中，以便less默认运行-f。

export LESS='-f'
