Moving and Renaming Files and Directories (mv) - Images: Japanese
Hey there, everyone!
This time, we're looking at the 'mv' command — your go-to tool for moving and renaming files and directories.
We've already covered rm and cp, and mv follows the same basic pattern: mv <source> <destination>. That said, the result can vary quite a bit depending on what you specify as the destination, so let's walk through each case one by one.
First, let's create a test file using the touch command.
[root@localhost ~]# touch test.txt [root@localhost ~]# ls test.txt
Now let's run the following command.
[root@localhost ~]# mv test.txt test1.txt
The syntax is mv <source> <destination>, so here we're "moving" test.txt to the same directory but under a different name. Let's check the result with ls.
[root@localhost ~]# mv test.txt test1.txt [root@localhost ~]# ls test1.txt
test.txt is gone and test1.txt has appeared — the file was renamed. To make this even clearer, you can also write it like this:
[root@localhost ~]# mv ./test.txt ./test1.txt
The ./ notation refers to the current directory, so this literally means "move test.txt to the same directory under the name test1.txt" — which is exactly what a rename is.
This might feel a bit strange if you're coming from Windows or macOS, where renaming and moving are separate operations. In UNIX-like systems, both are handled by the mv command. It just takes some getting used to.
By the way, if you try to "move" a file to itself, you'll get an error:
[root@localhost ~]# mv test.txt test.txt mv: `test.txt' and `test.txt' are the same file
Makes sense — it's telling you that source and destination are identical.
Next, let's try moving a file to a different directory. First, create a directory called test.
[root@localhost ~]# mkdir test [root@localhost ~]# ls test test1.txt
To move test1.txt into the test directory while keeping the same filename, do this:
[root@localhost ~]# mv test1.txt test/ [root@localhost ~]# ls test/ test1.txt
If you want to move the file and rename it at the same time, just specify the new name in the destination:
[root@localhost ~]# mv test1.txt test/test.txt [root@localhost ~]# ls test/ test.txt
Here, test1.txt was moved into the test directory and renamed to test.txt in a single step. Worth remembering.
And if you want to bring a file back to the current directory, you can use . (a single dot) as the second argument, which represents the current directory. It's a neat shorthand.
[root@localhost ~]# ls test/ test.txt [root@localhost ~]# mv test/test.txt . [root@localhost ~]# ls test test.txt
Just a single dot and the file lands right where you are. Very handy.
What about moving directories? That works just as easily with mv — no extra options needed.
[root@localhost ~]# ls test.txt test [root@localhost ~]# mv test test1 [root@localhost ~]# ls test.txt test1
Note that rm and cp required the -r option for directories, but mv does not. This is a common point of confusion, so keep it in mind.
And that covers the mv command. In the next article, we'll start looking at vi. See you there!
