请教如何用命令来批量修改文件名？[已经解决]

[aszxas]

例：
filename-1.txt.bak
filename-2.txt.bak
filename-3.txt.bak
filename-4.txt.bak

改为

filename-1.txt
filename-2.txt
filename-3.txt
filename-4.txt

用命令：
mv *.txt.bak *.txt
不行！

要如何写，谢谢。

x="1 2 3 4"
for xx in $x; do mv filename-$xx.txt.bak filename-$xx.txt ; done;

要是linux下有total commander楼主的问题就简单了，好怀念tc……

呵呵，大家可以多到linuxtoy去看看，那里有很多好东西的。
比如lz和ls的问题都有解决的：

Krusader－双面板文件管理器，跟tc很像的，虽然是kde的软件，不过gnome也没有问题了。

在 Nautilus 中执行批量重命名操作

ls说的我用过了，上次karron推荐给我用，用了一下，界面上来说的确跟tc非常相似，但一些操作上还是有差异的，比如lz说的批量重命名这个功能就没有。gnome下也有类似的软件，gnome-commander，也是界面神似，但功能差很多。

恩，因为我没有用，所以也不太清楚。但是linuxtoy和krusader的主页上都说新的1.8.0beta是有批量重命名文件的功能的。

RENAME(1) Perl Programmers Reference Guide RENAME(1)

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 exten‐
sion, you might say

rename ’s/\.bak$//’ *.bak

To translate uppercase names to lower, you’d use
