strings - Finds strings in an ASCII or binary file
strings [-aco] [-t format] [-n number] [file...]

-a Searches an entire object file, not just the initialized data space.
-c Searches only the comment section of the object file.
Sets the minimum string length (default: 4) to number.
-o Precedes each string by its offset (in octal) in the file.
Writes each string preceded by its byte offset from the start of the
file. The format is dependent on the single character used as the for-
mat argument, as follows:
d The offset is written in decimal.
o The offset is written in octal.
x The offset is written in hexadecimal.
Sets the minimum string length (default: 4) to number. (Obsolescent)
- Searches an entire object file, not just the initialized data space.
The name of a file to be searched for strings.
If you do not specify a file argument, strings reads from standard
A string is any sequence of 4 or more printing characters ending with a
newline or null character. The strings command is useful for identifying
random object files.
[Tru64 UNIX] If file specifies an archive file, output is generated for
each archive member as if the command had been run on each archive member
as a separate file. If -t is specified, the file offsets shown are relative
to the beginning of the archive.
[Tru64 UNIX] The -a and -c options modify the default behavior of search-
ing only in the initialized data space of object files.
[Tru64 UNIX] The -t format option should be used when multiple files are
specified as input. Without this option, it is not possible to determine
which string is associated with which file.
The following exit values are returned:
0 Successful completion.
>>0 An error occurred.
The following environment variables affect the execution of strings:
Provides a default value for the internationalization variables that
are unset or null. If LANG is unset or null, the corresponding value
from the default locale is used. If any of the internationalization
variables contain an invalid setting, the utility behaves as if none of
the variables had been defined.
If set to a non-empty string value, overrides the values of all the
other internationalization variables.
Determines the locale for the interpretation of sequences of bytes of
text data as characters (for example, single-byte as opposed to multi-
byte characters in arguments and input files) and to identify printable
Determines the locale for the format and contents of diagnostic mes-
sages written to standard error.
Determines the location of message catalogues for the processing of
