echo $"abc" 和echo "abc"的区别[已解决]

在rh的/etc/rc.sysinit里面很常见的现象,就是在字符串前面加了$符号,e.g:
echo -en $"\t\tWelcome to "
action $"Configuring kernel parameters: " sysctl -e -p /etc/sysctl.conf
等等

why?

请看Bash的man手册的解释。

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.

thx!

在rc.sysinit最前面加上LC_ALL=de_DE, 就看到效果了.
