    NAME

    strings - find printable strings in an object or binary file
     
    

    SYNOPSIS

    strings [-a | -] 
        [-t format | -o] [-n number | -number]  [-N name]  [file]...
    

     

    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.

    By default, strings looks at program sections that are loaded in memory. Program sections are identified by the section type SHT_PROGBITS. Sections that are loaded in memory are identified by the section flag SHF_ALLOC. Use elfdump(1) to display complete section information for a file.

    All sections can be inspected with the -a option. Individual sections can be inspected with the -N option.  

    OPTIONS

    The following options are supported:

    -a | -

    Look everywhere in the file for strings.

    -n number | -number

    Use a number as the minimum string length rather than the default, which is 4.

    -N name

    Look only in ELF section name. See elfdump(1). Multiple -N options can be specified to inspect multiple sections.

    If the -a or -option is specified, all -N options are ignored .

    -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 is written in decimal.

    o

    The offset is written in octal.

    x

    The offset is 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 reads from the standard input.

     

    ENVIRONMENT VARIABLES

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

    EXIT STATUS

    The following exit values are returned:

    0

    Successful completion.

    >0

    An error occurred.

     

    ATTRIBUTES

    See attributes(5) for descriptions of the following attributes:

    ATTRIBUTE TYPEATTRIBUTE VALUE

    AvailabilitySUNWtoo

    CSI

    Interface Stability

    The strings utility, including all options except -N, are specified by standards. See standards(5). The -N option is not currently specified by any standard.  

    SEE ALSO

    elfdump(1), od(1), attributes(5), environ(5), standards(5)  

    NOTES

    The algorithm for identifying strings is extremely primitive.

    For backwards compatibility, the options -a and - are interchangeable.
