===============================================================================
在文件和管道中寻找字符串，并将它们替换为其它内容
用法: fr [文件通配符1 文件通配符2 ...] {查找选项:查找内容} {替换选项:替换为}
[其它选项]
===============================================================================
查找选项:
-f: - 匹配精确串
-fic: - 匹配精确串（忽略大小写）
-r: - 正则表达式匹配
-ric: - 正则表达式匹配（忽略大小写）
-rnnl: - 跨行正则匹配
-rnnlic: - 跨行正则匹配（忽略大小写）
===============================================================================
替换选项:
-t: - 将匹配的内容替换为指定字符串
-tu: - 先将指定的“替换为”字符串变为大写，然后开始替换
-tl: - 先将指定的“替换为”字符串变为小写，然后开始替换
注意: 如果您正在使用正则匹配，那么您可以在“替换为”字符串中使用子表达式代换
(\0 ～ \9)
===============================================================================
其它选项:
-h -? - 当前屏幕
-s - 包含子目录
-exp - 启用内存扩展算法，将会加倍 fr 的内存使用量，但是很多时候可以极大地
提高执行效率。现已默认开启。
-noexp - 禁用内存扩展算法，参考：-exp 选项的说明。
-stdin - 从标准输入设备获得要查找的内容，并将结果从到标准输出设备（如果未指
定任何文件模板的话，则自动启用该选项）
-stdout - 像平时一样， 从文件中获得输入， 但将结果送到标准输出（而不是写回文
件）
-frc - 显示每个文件内发生的替换次数
-trc - 显示所有文件总共发生的替换次数
-errstop - 当遇到文件或子目录访问错误时，终止搜索任务。
默认: 遇到无法访问的子目录访跳过；遇到无法访问的文件时，打印错误信
息并继续
-ue - 为所有查找和替换选项应用 url encoding (percent-encoding, rfc 3986)
格式为：'pct-encoded = "%" HEXDIG HEXDIG'
===============================================================================
POSIX 和 Perl 风格的正则表达式:
- "find - replace" 完整支持 POSIX.2 扩展标准及 Perl 风格的正则表达式。
以下是支持的字符类及其对应关系:
POSIX perl 描述
--------------------------------------------------------------------
[:alnum:] 字母和数字
[:alpha:] \a 字母
[:lower:] \l 小写字母
[:upper:] \u 大写字母
[:blank:] 空格和制表符
[:space:] \s 空白字符
[:cntrl:] 控制字符
[:digit:] \d 十进制数字
[:xdigit:] \x 十六进制数字
[:graph:] 可打印字符（不包括空白符）
[:print:] \p 可打印字符（包括空白符）
[:punct:] 标点符号
- 以下是一些 perl 的特殊字符类:
perl POSIX等效 描述
--------------------------------------------------------------------
\o [0-7] 八进制数字
\O [^0-7] 非八进制数字
\w [[:alnum:]_] 单词组成
\W [^[:alnum:]_] 非单词组成
\A [^[:alpha:]] 非字母
\L [^[:lower:]] 非小写字母
\U [^[:upper:]] 非大写字母
\S [^[:space:]] 非空白符
\D [^[:digit:]] 非十进制数字
\X [^[:xdigit:]] 非十六进制数字
\P [^[:print:]] 非可打印字符
\< [^[:alpha:]_] 单词开始
\> [^[:alnum:]_] 单词结束
- 注意: posix 字符类是必须工作在集合中的（“[”和“]”内）。相反，perl 风格
的字符类是工作在集合运算之外的。
- 此外，为了便于在命令行输入一些特殊字符，特别定义了一下别名:
perl风格 POSIX风格 描述
-----------------------------------------------------------------------
\" [:dq:] 双引号
\' [:sq:] 单引号
\t [:tb:] 制表符
\n [:nl:] 换行符 (0x0A)
\r [:rt:] 回车符 (0x0D)
\b [:bs:] 退格符
===============================================================================
TCL 8.2 兼容的高级正则表达式（ARE）
- 为 -r:, -ric:, -rnnl:, -rnnlic: 等命令添加 '***:' 前缀即可开启高级正则表达
式功能。ARE 提供了比 POSIX ERE/BRE 更为强大的正则匹配语法，并且使用一套自定
义的字符类。有关 ARE 的详细信息，请访问：
http://baiy.cn/utils/_regex_doc/index.htm
===============================================================================
开关的前缀和后缀:
* 所有命令行开关（选项）都是大小写无关的（如: "-fic:" 和 "-FIC:"）
* 开关的前缀可以是 "-" 或 "/"（如: "/s" 和 "-s"）
* 开关的后缀可以是 ":" 或 "="（如: "/f:", "/f=", "-f:" 和 "-f=" 等效）
===============================================================================
应用示例:
fr *.txt *.htm -f:teh -t:the
fr *.txt -fic:"My Dir" -tu:"%ROOTDIR%"
fr *.cpp *.h -r:"***:(#define.*?)MY_DEF" /t:"\1HER_DEF"
fr *.txt -f:"abc%10%1A" -t:"def%00%1F" -ue
type server.log | fr /r:"Connected.*218.79" /t:"**Attack** \0"
type server.log | fr /r:"^(Smith|James).*\n" /t
unzip -l *.zip | fr /r:"^(.{22}:\d\d\s*|(A| \a| -|.*files$).*\n)" /t

===============================================================================
find and replace Ver 2.1.7.0424 by BaiYang / 2004 - 2012, Freeware
homepage - http://baiy.cn
===============================================================================
Find string in files or pipe, and replace it to another string
USAGE: fr [filePattern1 filePattern2 ...] {FindOption:StringToFind}
{ReplaceOption:StringToReplacement} [OtherOptions]
===============================================================================
FIND OPTIONs:
-f: - find
-fic: - find ignore case
-r: - regular expresion find
-ric: - regular expresion find ignore case
-rnnl: - regular expresion find ignore newline
-rnnlic: - regular expresion find ignore newline ignore case
===============================================================================
REPLACE OPTIONs:
-t: - change the match to"StringToReplacement"
-tu: - make the "StringToReplacement" upper case, and change the match
to it.
-tl: - make the "StringToReplacement" lower case, and change the match
to it.
NOTE: If find option you specified is a regular expresion method, the replace
option will support sub expressions (\0-\9) as well.
===============================================================================
OTHER OPTIONs:
-h -? - Is screen
-s - include sub folders
-exp - enable the memory expand algorithm, will double the memory usage,
but MUCH quick in many case. Now Default.
-noexp - disable the memory expansion algorithm. see also: -exp.
-stdio - get input from standard input device (keyboard and pipe),
and put the results to standard output device.
default when file pattern is omitted.
-stdout - get input from file(s) as normally, but put the results to
standard output device.
-frc - show File Replacements Count
-trc - show Total Replacements Count
-errstop - stop on a file or sub-directory access error (the old behave).
DEFAULT: ignore the access error and try to continue.
-ue - apply url encoding (percent-encoding, rfc 3986) for all find and
replacement options. 'pct-encoded = "%" HEXDIG HEXDIG'
===============================================================================
POSIX and perl style Regular Expression:
- "find - replace" fully support POSIX.2 Extended and Perl style Regular
Expresion. Here is a list of they character classes:
POSIX perl Description
--------------------------------------------------------------------
[:alnum:] letters and digits
[:alpha:] \a letters
[:lower:] \l lowercase letters
[:upper:] \u uppercase letters
[:blank:] space and tab characters
[:space:] \s whitespace characters
[:cntrl:] control characters
[:digit:] \d decimal digits
[:xdigit:] \x hexadecimal digits
[:graph:] printable characters excluding space
[:print:] \p printable characters including space
[:punct:] punctuation characters
- And here a some special char classes in perl:
perl POSIX equivalent Description
--------------------------------------------------------------------
\o [0-7] octal digit
\O [^0-7] non-octal digit
\w [[:alnum:]_] word character
\W [^[:alnum:]_] non-word character
\A [^[:alpha:]] non-alphabetic character
\L [^[:lower:]] non-lowercase character
\U [^[:upper:]] non-uppercase character
\S [^[:space:]] non-whitespace character
\D [^[:digit:]] non-digit
\X [^[:xdigit:]] non-hex digit
\P [^[:print:]] non-printable characters
\< [^[:alpha:]_] begin of word
\> [^[:alnum:]_] end of word
- note: posix char class must working in the square brackets. contrary,
perl's must stay outside of the brackets.
- And several alias has been created to help input some special char:
perl style POSIX style Description
-----------------------------------------------------------------------
\" [:dq:] double quotation
\' [:sq:] single quotation
\t [:tb:] table
\n [:nl:] new line (0x0A)
\r [:rt:] return (0x0D)
\b [:bs:] backspace
NOTE: the posix style alias also available on /t, /tu and /tl when using
the regex ("/r" and "/ric") match.
===============================================================================
TCL 8.2 Compatibal ARE expression:
- Use '***:' prefix with -r:, -ric:, -rnnl: or -rnnlic: to enable Advanced
Regular Expression mode. The ARE mode have more powerful expression then
POSIX BRE and ERE rule. And it has it's own char classes. More info at:
http://baiy.cn/utils/_regex_doc/index.htm
===============================================================================
SWITCH PREFIX and SUFFIX:
* All switchs (options) are case-insensitive (i.e: "-fic:" or "-FIC:")
* Switch Prefix can be either "-" or "/" (i.e: "/s" or "-s")
* Switch Suffix can be either ":" or "=" (i.e: "/f:", "/f=", "-f:" or "-f=")
===============================================================================
EXAMPLEs:
fr *.txt *.htm -f:teh -t:the
fr *.txt -fic:"My Dir" -tu:"%ROOTDIR%"
fr *.cpp *.h -r:"***:(#define.*?)MY_DEF" /t:"\1HER_DEF"
fr *.txt -f:"abc%10%1A" -t:"def%00%1F" -ue
type server.log | fr /r:"Connected.*218.79" /t:"**Attack** \0"
type server.log | fr /r:"^(Smith|James).*\n" /t
unzip -l *.zip | fr /r:"^(.{22}:\d\d\s*|(A| \a| -|.*files$).*\n)" /t
