Linux Command to find Strings in Binary or non ascii file

Is there any linux command to extracts all the ascii strings from an executable or other binary file? I suppose I could do it with a grep, but I remember hearing somewhere that such a command existed?

Solution 1:

The command you are looking for is strings

Its name is quite self-explanatory, it retrieves any printable string from a given file.

man strings gives:

STRINGS(1)

NAME
strings - find the printable strings in a object, or other binary, file

SYNOPSIS
strings [ - ] [ -a ] [ -o ] [ -t format ] [ -number ] [ -n number ] [--] [file ...]

Solution 2:

The strings command is the way to go for this particular type of problems. Sometimes you also have to pipe it out to grep.

For example:

strings somebinaryfile | grep textuwanttofind
