Puede utilizar de grep
todos modos para buscar en el archivo; realmente no le importa si el archivo de entrada es realmente texto o no. De 'man grep':
-a, --text
Process a binary file as if it were text; this is equivalent to the --binary-files=text option.
--binary-files=TYPE
If the first few bytes of a file indicate that the file contains binary data, assume that the file is
of type TYPE. By default, TYPE is binary, and grep normally outputs either a one-line message saying
that a binary file matches, or no message if there is no match. If TYPE is without-match, grep assumes
that a binary file does not match; this is equivalent to the -I option. If TYPE is text, grep
processes a binary file as if it were text; this is equivalent to the -a option. Warning: grep
--binary-files=text might output binary garbage, which can have nasty side effects if the output is a
terminal and if the terminal driver interprets some of it as commands.
Marque las palabras de precaución al final del segundo párrafo. Es posible que desee redirigir los resultados de grep a un nuevo archivo y examinar esto con vi / less.
