在bash重命名文件 [英] Renaming files in bash

问题描述

我的目录下有命名为20130101_temp.txt，20130102_temp.txt等。

My directory has many files named as "20130101_temp.txt", "20130102_temp.txt", etc.

我如何删除所有这些文件的名称_temp。即，重命名为20130101_temp.txt 20130101.txt。

How do I remove the "_temp" in the names of all these files. i.e., rename 20130101_temp.txt to 20130101.txt.

推荐答案

使用bash：

for x in *_temp.txt
do
    mv $x ${x%%_temp.txt}.txt
done

还有随叫Perl的（至少在Ubuntu）的多用途改名，接受一个正前pression，所以你可以完成的同样的事情

There's also a utility that comes with Perl (at least on Ubuntu) called rename which takes a regular expression, so you could accomplish the same thing with:

rename -n 's/_temp\.txt$/.txt/' *_temp.txt

的 -n 选项启动试运行，将只显示你是怎么回事改名。删除其实际执行的重命名。

The -n option initiates a "dry run" that will only show you what is going to be renamed. Remove it to actually perform the rename.
