strings - find printable strings in an object or binary file
strings [-a | -] [-t format | -o] [-n number | -number] [-N name] [file]...
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.
The following options are supported:
-a | -
-n number | -number
If the -a or -option is specified, all -N options are ignored .
The following operand is supported:
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.
The following exit values are returned:
See attributes(5) for descriptions of the following attributes:
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.
elfdump(1), od(1), attributes(5), environ(5), standards(5)
The algorithm for identifying strings is extremely primitive.
For backwards compatibility, the options -a and - are interchangeable.
