请问zhuzhixin，你的环境是什么？
2. 我看了一下rename的man，将你的语句修改如下：
rename .mp3 .MP3 *.mp3
这样就可以了 [i=s] 本帖最后由 zhuzhixin 于 2009-4-16 17:36 编辑 [/i]

NAME
rename - renames multiple files
SYNOPSIS
rename [ -v ] [ -n ] [ -f ] perlexpr [ files ]
DESCRIPTION
"rename" renames the filenames supplied according to the rule specified as the first argument. The perlexpr
argument is a Perl expression which is expected to modify the $_ string in Perl for at least some of the filenames
specified. If a given filename is not modified by the expression, it will not be renamed. If no filenames are
given on the command line, filenames will be read via standard input.
For example, to rename all files matching "*.bak" to strip the extension, you might say
rename 's/\.bak$//' *.bak
To translate uppercase names to lower, you’d use
rename 'y/A-Z/a-z/' *
