Two very useful tools for extracting essential details on your Linux system OS and hardware arescreenfetch和geofetch.
Each of these tools is actually a lengthy bash script that fetches the information from your system for you and presents it in an attractive manner with the distribution logo on the left and details on the right--essentially "screen shots" of your system. Neither is likely to be installed on your system by default, but each can be installed with a single command.
screenfetch
你可以安装screenfetch借sudoapt安装screenfetch.要么sudo yum安装screenfetch。ScreenFetch是一个绰号近6,500行的脚本。它将自动检测您安装的分发，内核，正常运行时间，您正在使用的包，您正在使用的shell，整体和可用的磁盘空间，CPU，GPU和内存（在使用中使用和可用）。它还显示了与其运行的任何分布相关的徽标的ASCII艺术Rendition，但如果您想只是查看详细信息列表，则可以关闭此操作。
来自此命令的输出将如此如此（在Ubuntu上）看起来，但在颜色中：
$ screenfetch ./+o+- shs@dragonfly yyyyy- -yyyyyy+ OS: Ubuntu 20.04 focal ://+//////-yyyyyyo Kernel: x86_64 Linux 5.4.0-52-generic .++ .:/++++++/-.+sss/` Uptime: 25d 23h 44m .:++o: /++++++++/:--:/- Packages: 2882 o:+o+:++.`..```.-/oo+++++/ Shell: bash 5.0.17 .:+o:+o/. `+sssoo+/ Disk: 62G / 541G (12%) .++/+:+oo+o:` /sssooo.

To omit the ASCII art logo and see just the system details, add a-N选项。
$ screenfetch -n shs @ dragonfly os：ubuntu 20.04焦点内核：x86_64 linux 5.4.0-52-generic正常运行时间：25d 23h 50m套装：2882 shell：bash 5.0.17磁盘：62g / 541g（12％）CPU：英特尔Core2DUO E8400 @ 2x 2.997GHz GPU：AMD / ATI CAICOS [RADEON HD 6450/7450 / 8450 / R5 230 OEM] RAM：903MIB / 5944MIB
添加A.-v.（verbose）选项将脚本将脚本连接到显示系统信息时显示。毕竟“查找”消息后，它将显示通常的输出。

Thescreenfetch脚本已安装为/ usr / bin / screenfetch。
$ ls -l /usr/bin/screenfetch -rwxr-xr-x 1 root root 244084 Nov 27 15:17 /usr/bin/screenfetch
新辛精
The新辛精脚本甚至延长screenfetchscript. It has over 10,000 lines and displays some additional system information. You can install it with a command such assudo apt install neofetch要么sudo dnf安装neofetch。Likescreenfetch,新辛精detects the information that it displays and adds an ASCII art depiction of the distribution logo to the display.

如您所见，主机的行（系统类型），屏幕分辨率和终端都包含在内screenfetch, but the information on disk capacity and usage is not. By usingsudo，我能够获取包含的磁盘信息。
Many other options appear to be available as well.

包起来
这俩screenfetch和新辛精脚本提供了非常有用和很好的格式化的重要系统信息。
新辛精可能是较新的工具（通过包含字符串“neo”的名称建议）并提供一些其他选项。这两种工具都可以易于使用，作为键入他们的名称，它们提供了重要的系统细节。
