Pydf替代“df”命令检查不同颜色的磁盘使用情况

“pydf”(Python的磁盘文件系统 )是一种先进的命令行工具和一个很好的替代Linux的“ DF COMAND” 。 它是用来在Linux文件系统,同样喜欢df命令显示的使用和可用的磁盘空间量,但在不同的颜色。 pydf命令的输出可以根据您的需要进行自定义。

Pydf检查磁盘使用情况的命令

这种“pydf”命令被写在在Linux安装的文件系统,使用自定义的颜色不同的文件系统类型,显示磁盘使用和可用空间的量Python语言。

正在安装pydf

默认情况下,pydf工具未安装在Linux发行版上,您需要使用第三方存储库安装它。 因此,首先使EPEL软件库 ,之后启用它,使用下面的“ Yum命令 ”进行安装。

在RHEL / CentOS / Fedora / Scientific Linux上

# yum install pydf

在Debian / Ubuntu / Linux Mint

在基于Debian的发行版中,pydf工具是从包管理系统速效,则可以使用“安装apt-get命令 ”,如下图所示。

$ sudo apt-get install pydf

如何使用pydf命令

如果没有指定参数运行只是“pydf”命令,它会与所有已安装文件系统一起显示磁盘空间使用情况的信息只。

# pydf

要检查哪些文件具有0块,简单的运行与“-a”“-ALL”的说法大致如下指挥系统。

# pydf -a

要以可读的格式输出,使用选项“-h”,这将打印尺寸(如10K,10M,10G)。

# pydf -h
Filesystem Size  Used Avail Use%                                            Mounted on

/dev/sdc1  492G  262G  205G 53.3 [#####################...................] /videos

要打印在千字节(例如,1024块的大小)选择使用“-k”,如下图所示尺寸。

# pydf -k

要打印摘要输出以兆字节(例如,1048576块大小)使用选项“-m”,如下图所示。

pydf -m
Filesystem   Size   Used  Avail Use%                                           Mounted on

/dev/sdc1  503960 268536 209824 53.3 [#####################..................] /videos

要打印在千兆字节(例如,1073741824)的大小,指定选项“-g”,如下图所示。

# pydf -g
Filesystem   Size   Used  Avail Use%                                           Mounted on

/dev/sdc1  503960 268536 209824 53.3 [#####################..................] /videos

要查看有关的inode而不是块中的信息,使用参数“-i”为如下。

# pydf -i
Filesystem Nodes  Used Avail Use%                                            Mounted on

/dev/sdc1    31M 2033k   29M  6.4 [###.....................................] /videos

如果要禁用colourised输出,只需使用选项“-BW”。

# pydf --bw

/dev/sdc1  492G  262G  205G 53.3 [#####################...................] /videos

如何自定义pydf颜色

pydf有自己的配置文件,您可以在其中定义自己的自定义颜色,给出一些额外的感觉并查看输出。

# vi /etc/pydfrc

欲了解更多信息通过击中在终端“ 人pydf”读pydf命令的手册页。
