对于给定的每个文件，GNU 字符串都会打印可打印字符序列，这些序列至少有 4 个字符长（或使用以下选项给出的数字），并且后面跟着一个不可打印字符。
根据 strings 程序的配置方式，它将默认显示它在每个文件中找到的所有可打印序列，或者仅显示可加载的初始化数据部分中的序列。 如果文件类型无法识别，或者如果 strings 正在从标准输入读取，那么它将始终显示它能找到的所有可打印序列。
为了向后兼容，在命令行选项 just - 之后出现的任何文件也将被完整扫描，无论是否存在 -d 选项。
strings 主要用于确定非文本文件的内容。

-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 displayable characters that are at least min-len characters long. If not specified a default minimum length of 4 is used. The distinction between displayable and non-displayable characters depends upon the setting of the -e and -U options. Sequences are always terminated at control characters such as new- line and carriage-return, but not the tab character. -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 (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). -U [d|i|l|e|x|h] --unicode=[default|invalid|locale|escape|hex|highlight] Controls the display of UTF-8 encoded multibyte characters in strings. The default (--unicode=default) is to give them no special treatment, and instead rely upon the setting of the --encoding option. The other values for this option automatically enable --encoding=S. The --unicode=invalid option treats them as non-graphic characters and hence not part of a valid string. All the remaining options treat them as valid string characters. The --unicode=locale option displays them in the current locale, which may or may not support UTF-8 encoding. The --unicode=hex option displays them as hex byte sequences enclosed between <> characters. The --unicode=escape option displays them as escape sequences (\uxxxx) and the --unicode=highlight option displays them as escape sequences highlighted in red (if supported by the output device). The colouring is intended to draw attention to the presence of unicode sequences where they might not be expected. -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.
strings 打印二进制中的所有字符串：
strings path/to/file
strings 将结果限制为至少 n 个字符长的字符串：
strings -n n path/to/file
strings 在每个结果前面加上它在文件中的偏移量：
strings -t d path/to/file
strings 在每个结果前面加上文件内的十六进制偏移量：
strings -t x path/to/file
