not the most efficient one, since i am new to perl. but enough for your work
#!/usr/bin/perl
@list = `ls test/*.b`;
foreach $a (@list){
chomp($a);
$com = "mv ".$a." $a.c";
exec($com);
}
assume your dir is "test" your old extension is .b , new one is .c
I hope to see perl experts to show me the greatest power of perl by doing same job using many and much more efficient ways :)

看看这个可以么？没在公司，不能测试
for example from *.abc to *.cde
source=`ls *.abc`
for file in $source
do
newfile=`echo $file | sed s'/.abc/.cde/g'`
#先不要用mv， 用echo看看$newfile名字对不，
#免得给你文件弄坏了
mv $file $newfile
done
source=`ls *.abc`
for file in $source
do
newfile=`echo $file | sed s'/.abc/.cde/g'`
#先不要用mv， 用echo看看$newfile名字对不，
#免得给你文件弄坏了
mv $file $newfile
done
man renamerename .foo .bar *.foo
rename是函数吧，她要的应该是shell

tested in Solaris 2.5 successfully.
Before test:
~/tmp/test/[116]> ls
~/tmp/test/[116]> 1 2 1.abc 2.abc 3.dd
After test:
~/tmp/test/[116]> ls
~/tmp/test/[116]> 1 2 1.cde 2.cde 3.dd
Please try.

记得你好象曾经提起过有一个命令可以查当前是什么系统
比如telnet进去,想知道是什么操作系统,什么机型.怎么实现呢?

uname -a?
rename是函数吧，她要的应该是shell
看清楚，是RENAME(1)，不是RENAME(2)。
uname -a?
