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 NEW-
LINE 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 TYPE | ATTRIBUTE VALUE |
+-----------------------------+-----------------------------+
|Availability |SUNWtoo |
+-----------------------------+-----------------------------+
|CSI |Enabled |
+-----------------------------+-----------------------------+
|Interface Stability |See below. |
+-----------------------------+-----------------------------+
The strings utility, including all options except -N, are specified by standards. See standards(5). The -N option is not currently speci-
fied 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.
