Considerations for Linux

1. Precautions

1. Strictly case sensitive
2. Everything in Linux 文件形式保存including hardware.
   • The hard disk file is /dev/ad[ap]
   • The CD-ROM file is /dev/sr0, etc.
3. Linux does not rely on extensions to distinguish file types
   • Compressed package: "*.*gz" ".bzx" ".tar.bz2" ".tgz" etc.
   • Binary package: ".rpm"
   • Web page file: “.html” “.php”
   • Script file: ".sh"
   • Configuration file: ".conf"

But for convenience, the extension will be written for the above files, and the system can recognize it normally without writing it.

4. All Linux storage devices must be mounted before they can be used.

   • Such as: hard disk USB CD-ROM

5. Programs under windows cannot be installed and run directly in Linux.
