NAME

rence of from in their name by to.
For example, given the files foo1, ..., foo9, foo10, ..., foo278, the
commands
rename foo foo0 foo?
rename foo foo0 foo??
will turn them into foo001, ..., foo009, foo010, ..., foo278.

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
