以前寫的，用來加強對 bash builtin 的記憶..hehehe
灌水相當合用 :)

man bash, 找到 QUOTING 那段說明:
Words of the form $'string' are treated specially. The word expands to
string, with backslash-escaped characters replaced as specifed by the
ANSI C standard. Backslash escape sequences, if present, are decoded
as follows:
\a alert (bell)
\b backspace
\e an escape character
\f form feed
\n new line
\r carriage return
\t horizontal tab
\v vertical tab
\\ backslash
\' single quote
\nnn the eight-bit character whose value is the octal value
nnn (one to three digits)
\xHH the eight-bit character whose value is the hexadecimal
value HH (one or two hex digits)
\cx a control-x character
The expanded result is single-quoted, as if the dollar sign had not
been present.
[color=darkred] A double-quoted string preceded by a dollar sign ($) will cause the
string to be translated according to the current locale. If the cur-
rent locale is C or POSIX, the dollar sign is ignored. If the string
is translated and replaced, the replacement is double-quoted.[/color]

有用啊. 不是提到 locale 了嗎?

the string is translated and replaced, the replacement is double-quoted.
我想我会很快忘记的

大侠~你理解的locale是什么意思啊？
能用中文解释下Me？
網中人 回复于：2005-09-08 16:25:22
簡單來說, 就是"當地語系", 比方 zh_CN, zh_TW.Big5 之類.
你可輸入 locale 命令查看語系設定.
你可用 export LC_ALL=xxxxxxxx 來改變語系設定值.
其中, LANG=xxxxxxxx 則需另設.
更多的, "找男人"跟"挖股溝"吧.......... ^_^

试了几个locale,没感觉啥 :?:

那在 X window 下測中日韓越幾種不同的"文字"看看?

你试echo是没用的
localmessage记录在每个程序所用的mo文件中比如
LC_ALL=zh_CN date
其实要去 /usr/share/local/zh_CN/之类的地方找到date.mo取出中文信息来显示
我的系统中是没有echo.mo和bash.mo的 :evil: :mrgreen:

gettext大概就是干这个活儿的:mrgreen:
