The story of the stupid rabbit-learn about Ubuntu and Linux (31 ~ 33)

(31) Partition
There is a door on the wall of our house with three letters on it-USB
　　
This door is another interface for us to communicate with the outside world (the most important thing is the network). Every time the red light on the door lights up, something is connected to the USB, I have to open the door. Sometimes the door is a small container like a room, very small, usually only a few hundred megabytes to several GB size, there are some files like my room. At this time, the master is generally asking me to move things, either from the house to the house or from the house to the house. Sometimes when I open the door, it is not a room, but a device, such as a mouse or a camera, that is, let me operate these devices. The host receives the camera named Moto.
E6. I heard that this is actually a mobile phone. The camera above can be used on the computer through the USB interface. No matter what, we can play this thing and connect it to it, the mouse is even more difficult. But in general, there are many cases of external small container room to the USB door. This small container room is called a USB flash disk, and there is a bigger one, that is, a mobile hard disk. Whenever a USB flash drive comes in, I use it as a part of my house.
　　
To be a part of my house, We need to name it. How can I access it? Like your home, what is the kitchen, which is the toilet, what is the master bedroom, the balcony, and the space? The same is true for me. I have to have a name for access. Here we need to describe the hard drive we live on. The hard drive we live in is the same as the one in which you live. It's not a whole room where everyone is in disorder and things are littered. You also need to separate Several partitions. The number and size of the partition are based on the requirements of the host during installation. For example, if I live in this partition, four partitions are separated, this is equivalent to four rooms with walls. A card is hanging on the door of a small room:/boot
I live in this room, my single room, as the boss ...... A little special privilege is understandable. In another big room, the name is/home, which is used by the host to put his things, what documents, movie, and GEA, so this is very big. There is also a swap that does not store things at ordinary times. This is used for working programs. When the program is running, do they not want to put things in the work room? If it cannot be put, it will be temporarily put in this room. However, since our work room is very large, it is basically useless. In addition to these, there is one more room left. This is called "/" and the learning name is root partition. Other rooms can be none, but this room cannot be none. If we want to stay somewhere, no. However, although other rooms can be separated, the corresponding space is still available. For example,/boot can not only create a single room for me, but also not separate zones for me, but even if it is not the case, I have to draw a place and write/boot with chalk, indicating that it is the place where I live.
　　
Come back and talk about the USB flash drive. After the USB flash drive is connected, I also treat it as a small one and give it a sign at the door. Generally, it is/Media/XXX, and XXX is the name of the USB flash drive. Generally, a USB flash drive has a name, or a volume label. In this way, you can distinguish between individual rooms. For example, to let mplayer play a movie, I have to explain where the movie is put. If I say: In the biggest room where a bunch of masters are put, it's very cool. It's better to simply say: It's easy to get down to the/home/lanwoniu/directory.

(32) Mounting
　　
This time, the host connects to a container space on the USB, but it is still relatively large, 4 GB. I looked at it carefully and didn't find the name of the device. It was okay. The name was a person. I gave him a name and hung it with a sign:/Media/4.1g.
If there is no name, it can be dropped. If there is no brand, it cannot be dropped. We have heard of this brand mounting process in our professional words. Mounting means listing, that is, hanging a sign at the door of a room and naming them. It's time to work. Just say the name of the room. The name, or brand, Is a sign and can be changed at will. For example, a partition is mounted to the/home/directory, that is, a room a (called a) is mounted to the/home/brand. Then the host said to check what is in/home/, and I will list the items in Room A for the host. When you look back, you may mount another partition to/home/. It is very easy to remove/home/from the door of Room A and hold it at the door of room B. The host needs to check what is in the card/home/folder. I should show the list of things in Room B to the host. Unexperienced owners may be surprised: Wow ~ Why did I/home/get rid of all those items !! Where have you been !!
As a matter of fact, the original things are still well placed in Room A, but now room B is renamed/home.
　　
I am sorry for the waste. Back to the 4G room connected this time. After the 4G room was connected, I had not waited for the host to send a message. I checked it first, and it was all JPG files, I don't understand these files, but I know someone can understand them, so I can quickly report to the masters through the graphic interface: the pictures you inserted appear to be all in it, do you want me to find F-spot for you ?.
　　
F-spot is a photo management program. It helps the owner to export photos from mobile devices (small space like containers) to the hard disk and manage photos by time. The host wants a photo of April last March, and he will be able to find it immediately. In addition, it can also report the photo information, such as what camera is used, the background aperture, shutter, and ISO are used, and so on. Although F-spot can organize photos, it cannot be edited or modified. Sometimes, the photo of the host often needs to adjust the color slightly to make some effect, there are many people who call this ps, because the software used to do this kind of thing is called Photoshop and PS. Gradually, the action of processing photos with Photoshop is called ps. I don't have Photoshop here, but there is another strong person who handles photos-gimp.
(33) gimp
　　
Gimp is an artist who can draw many beautiful pictures. Of course, the beauty and beauty are based on the Aesthetic View of the master. For me, the things he made are just a file full of 0101001, which is no different from other files. Although he can create a colorful world on a piece of white paper, most of the work he has to do is to adjust a picture that has already been painted. Generally, the photo taken by the host using a digital camera is copied to the computer using a USB flash drive, and then gimp is called to adjust the brightness and color of the photo. Sometimes gimp is also used to make some effects, such as the effects of oil painting, that is, the photos are made into a painting like the painting; there is also a embossed image, or a photo frame, he can do it. In the past, the copied photos were several hundred kb, but most of the photos recently taken by the host were at least 2 MB. Others did not know what was going on, but they could not help copying the photos to F-spot, he can understand the EXIF information of the photo. He told me that the previous photo was named Nikon.
5900 of cameras are taken, and now all these 2 m cameras use Pentax.
K-M. I asked my sister Fox to check the two cameras. 5900 is a 5 million pixel DC, and K-M is a 10.2 million pixel SLR camera. No wonder the photo is too big. However, it is difficult for a 2 m photo file to break down the gimp file and open it after a flash. He said that even 20 m files are okay, but we have never seen them, the main reason is that the host's camera is not that big.
　　
Like Sister Fox, gimp can install many plug-ins to implement various functions and effects. The functions are not lost in Photoshop. However, gimp is not very easy to use. It is not as easy to use as PS. After all, the PS is expensive. I heard that a set of products cost thousands of yuan and a penny. If you spend so much money to go home to the software, how can you listen to the host without being convinced. Let's take a look at gimp. There is always a pair: I am like this, and I love to use a useless architecture. The master is more reasonable and can understand that gimp is indeed competent, otherwise ...... Hum, don't look at the good relationship between gimp and me. Maybe you have to be taken out of the hard disk by the super cool.
