Simple and Easy-Three Tips for Linux

Article Title: Simple and Easy-Three Tips for Linux operating systems. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
　　 Install dual Linux
The author's computer is equipped with WinXP and Red Hat Linux9 systems. Therefore, we need to prepare a blank partition before installing another Linux. Of course, there is also a Linux installation CD, I choose Turbo Linux 10. Then, set/etc/grub. the title Red Hat Linux (2.4.20-8) Section in conf is recorded (if LILO is used as the boot loader, the boot information in/etc/liloconf is recorded ). After all these preparations are ready, let's get started!
　　
Put the CD in the optical drive and boot it into the Linux installation program. Do not select automatic partitioning when installing the CD to the partition, instead, select manual partitioning (because automatic partitioning may damage the Partition Table ). Keep the original partition on the hard disk and create the Linux EXT partition on the blank partition prepared previously. The Boot Tool uses GRUB. I personally think it is intelligent.
　　
After a series of installation settings, click Next. After the installation is complete, restart the computer. In the GRUB boot loader, the "RedHatLinux" option has disappeared. Only Windows and TurboLinux start options are available. In this case, go to TurboLinux and edit/boot/grub/Srub. conf file (you can also edit/etc/grub. conf file. If LILO is used as the Boot Tool, edit lilo. conf file) to add the boot information recorded previously to the file. For example, the author adds the following paragraph to grub. conf.
　　
Title Red Hat Linux (2.4.20-8)
　　
Root (hd0, 9)
　　
Kernel/vmlinuz-2.4.20-8 ro root = LABEL =/
　　
Hdc = ide-scsi
　　
Initrd/initrd-2.4.20-8.img
　　
After editing, save and restart the computer. Does the familiar Red Hat Linux appear in the GRUB boot tool? Select "go". Everything is OK! Is it easy? If the hard disk is large enough, you can install multiple Linux systems in the same way.
Note: It is best to back up the system partition table before installation. When formatting the hard disk by the installer, you must only format the new partition to avoid unnecessary losses.
　　
　　 Use find to create an MP3 list
In Linux, the commonly used MP3 player is xmms. We can use the find command to easily create a playlist for it:
　　
Find/-name * mp3-print> mp3.1ist
　　
In this way, all MP3 files in various directories on the machine can be made into a playlist and loaded in xmms. In addition, the find command also has many parameters to filter the required files. For example, my machine has a lot of MP3 for English learning, and the file size is around 2 MB, other common songs are less than 4 MB. to separate them from the songs, you can use the following methods:
　　
Find/-name *. mp3-size-3000 k-print> eng. list
　　
Find/-name *. mp3 + size + 3000 k-print> music. list
　　
　　 Automatic Control of Num, Caps, and Scoll
When Linux is started, the default Num Lock is disabled. Sometimes it is inconvenient to enter a keypad, such as logging on and entering a digital password. How can I enable the Num Lock key automatically upon startup? In Linux, a command setleds is provided to control these locking keys. The general usage is as follows: for example, open Num Lock in tty1 of the console, and enter "setleds + num" in the command line.
　　
If the usage of other keys is the same, replace num with caps and scroll. In addition, you can add the-L parameter to setleds to turn on the prompt light without changing the keyboard status. For other usage instructions, refer to the Help file. Root users can change the status of other tty, while normal users can only log on to tty.
