Renaming files or folders under Linux

To rename files or directories under Linux, you can use the mv command or the rename command. Here we share how to use both.

Note, if there is also a file of 1234 in the current directory, this The file will be overwritten.

The following introduces the usage of the rename command in the Linux system.

Create file names with similar specifications in batches. [The first step of testing]

[root@linuxidc net]# for i in `seq -w 10`
> do touch stu\_$i\_linux.jpg
> done
[root@linuxidc net]# sl
total 0
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_01_linux.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_02_linux.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_03_linux.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_04_linux.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_05_linux.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_06_linux.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_07_linux.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_08_linux.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_09_linux.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_10_linux.jpg

Then, use rename to modify

[root@linuxidc net]# rename \_linux '' *.jpg
[root@linuxidc net]# sl
total 0
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_01.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_02.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_03.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_04.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_05.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_06.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_07.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_08.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_09.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:22 stu_10.jpg

Note that if you want to replace the underscore, you cannot add any quotation marks.

Create some test files:

[root@linuxidc net]# for i in `seq -w 10`; do touch stu\_$i\_linux.jpg; done
[root@linuxidc net]# sl
total 0
-rw-r--r-- 1 root root 0 Oct 9 21:58 stu_01_linux.jpg

-rw-r--r-- 1 root root 0 Oct 9 21:58 stu_03_linux.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:58 stu_04_linux.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:58 stu_05_linux.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:58 stu_06_linux.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:58 stu_07_linux.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:58 stu_08_linux.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:58 stu_09_linux.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:58 stu_10_linux.jpg
[root@linuxidc net]# rename '\_linux' '' *.jpg
[root@linuxidc net]# sl

-rw-r--r-- 1 root root 0 Oct 9 21:27 stu_07_linux.jpg
-rw-r--r-- 1 root root 0 Oct 9 21:27 stu_08_linux.jpg

If the rename version is the perl version, the rename command supports regular expressions; therefore, under the perl version of rename, the above command can be executed successfully. If The rename version is the c version, then the above command is unsuccessful.

This is a version support issue, so there is no need to delve into it.

The previous problem may be caused by his rename version not being supported. So, the focus here is rename, although this command is not very important. But it's actually quite useful, isn't it?

Of course, some people will say, you are all in the same directory, what if I am in a different directory?
