STRINGS(1)						      General Commands Manual							STRINGS(1)

NAME

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

SYNOPSIS

       strings [ - ] [ -a ] [ -o ] [ -number ] [file ...]

DESCRIPTION

       Strings	looks  for ASCII strings in a binary file or standard input.  Strings is useful for identifying random object files and many other
       things.	A string is any sequence of 4 (the default) or more printing characters ending with a newline or a null.  Unless  the  -  flag	is
       given,  strings	looks in all sections of the object files except the (__TEXT,__text) section.  If no files are specified standard input is
       read.

       The options to strings(1) are:

       -a     This option causes strings to look for strings in all sections of the object file (including the (__TEXT,__text) section.

       -      This option causes strings to look for strings in all bytes of the files (the default for non-object files).

       -o     Preceded each string by its offset in the file (in decimal).

       -number
	      The decimal number is used as the minimum string length rather than the default of 4.

       od(1)

BUGS

       The algorithm for identifying strings is extremely primitive.
