Linux中grep 文件提示Binary file /var/log/messages matches

我们Linux系统上经常通过grep命令检索关键字，有时候会提示Binary file matches的信息，我们在这里可以通过-a 参数。

grep test /var/log/messages
Binary file /var/log/messages matches

#man grep

File and Directory Selection

-a, --text

Process a binary file as if it were text; this is equivalent to the --binary-files=text option.

grep -a test /var/log/messages

• -a, --text equivalent to --binary-files=text，即让二进制文件等价于文本。
