Description

The strings utility looks for ASCII strings in a binary file. A string is any sequence of 4 or more printing characters ending with a newline or a null character.

strings is useful for identifying random object files and many other things.

Options

The following options are supported:
-a | -
Look everywhere in the file for strings. If this flag is omitted, strings only looks in the initialized data space of object files.
-n number | -number
Use a number as the minimum string length rather than the default, which is 4.
-o
Equivalent to -t d option.
-t format
Write each string preceded by its byte offset from the start of the file. The format is dependent on the single character used as the format option-argument:

d
The offset will be written in decimal.
o
The offset will be written in octal.
x
The offset will be written in hexadecimal.

Operands

The following operand is supported:
file
A path name of a regular file to be used as input. If no file operand is specified, the strings utility will read from the standard input.

Environment

See environ(5) for descriptions of the following environment variables that affect the execution of strings: LC_CTYPE , LC_MESSAGES , and NLSPATH .

Exit Status

The following exit values are returned:
  1. Successful completion.
    >0
    An error occurred.

    Notes
