Описание (Description)
For each file given, GNU strings
prints the printable character
sequences that are at least 4 characters long (or the number
given with the options below) and are followed by an unprintable
character.
Depending upon how the strings program was configured it will
default to either displaying all the printable sequences that it
can find in each file, or only those sequences that are in
loadable, initialized data sections. If the file type is
unrecognizable, or if strings is reading from stdin then it will
always display all of the printable sequences that it can find.
For backwards compatibility any file that occurs after a command-
line option of just -
will also be scanned in full, regardless of
the presence of any -d
option.
strings
is mainly useful for determining the contents of non-text
files.
Параметры (Options)
-a
--all
-
Scan the whole file, regardless of what sections it contains
or whether those sections are loaded or initialized.
Normally this is the default behaviour, but strings can be
configured so that the -d
is the default instead.
The -
option is position dependent and forces strings to
perform full scans of any file that is mentioned after the -
on the command line, even if the -d
option has been
specified.
-d
--data
Only print strings from initialized, loaded data sections in
the file. This may reduce the amount of garbage in the
output, but it also exposes the strings program to any
security flaws that may be present in the BFD library used to
scan and load sections. Strings can be configured so that
this option is the default behaviour. In such cases the -a
option can be used to avoid using the BFD library and instead
just print all of the strings found in the file.
-f
--print-file-name
Print the name of the file before each string.
--help
Print a summary of the program usage on the standard output
and exit.
-
min-len
-n
min-len
--bytes=
min-len
Print sequences of characters that are at least min-len
characters long, instead of the default 4.
-o
Like -t o
. Some other versions of strings
have -o
act like
-t d
instead. Since we can not be compatible with both ways,
we simply chose one.
-t
radix
--radix=
radix
Print the offset within the file before each string. The
single character argument specifies the radix of the
offset---o
for octal, x
for hexadecimal, or d
for decimal.
-e
encoding
--encoding=
encoding
Select the character encoding of the strings that are to be
found. Possible values for encoding are: s
=
single-7-bit-byte characters (ASCII, ISO 8859, etc.,
default), S
= single-8-bit-byte characters, b
= 16-bit
bigendian, l
= 16-bit littleendian, B
= 32-bit bigendian, L
=
32-bit littleendian. Useful for finding wide character
strings. (l
and b
apply to, for example, Unicode UTF-16/UCS-2
encodings).
-T
bfdname
--target=
bfdname
Specify an object code format other than your system's
default format.
-v
-V
--version
Print the program version number on the standard output and
exit.
-w
--include-all-whitespace
By default tab and space characters are included in the
strings that are displayed, but other whitespace characters,
such a newlines and carriage returns, are not. The -w
option
changes this so that all whitespace characters are considered
to be part of a string.
-s
--output-separator
By default, output strings are delimited by a new-line. This
option allows you to supply any string to be used as the
output record separator. Useful with
--include-all-whitespace where strings may contain new-lines
internally.
@
file
Read command-line options from file. The options read are
inserted in place of the original @file option. If file does
not exist, or cannot be read, then the option will be treated
literally, and not removed.
Options in file are separated by whitespace. A whitespace
character may be included in an option by surrounding the
entire option in either single or double quotes. Any
character (including a backslash) may be included by
prefixing the character to be included with a backslash. The
file may itself contain additional @file options; any such
options will be processed recursively.
