Getting Started with Linux (2) _ Tips for Beginners

1 Considerations for Learning Linux

1. Strictly case -sensitive (commands, files, options)
2. All content in Linux is saved as a file , including hardware

• Hard disk file is/dev/sd[a-p]
• CD-ROM files are/dev/sr0 etc.

1. Linux does not differentiate between file types by extension , but by file permissions , which is different from windows. But the habit is to name the file type. do not write and can run normally , but it is difficult to identify management. So most of the files in win can't be run on Linux
2. All Linux storage devices must be mounted before users can use them, including hard disks, USB drives, and discs
3. Programs under Windows cannot be installed and run directly in Linux
