If an argument is the absolute file name of a disk device node contain‐ ing a mounted file system, df shows the space available on that file system rather than on the file system containing the device node. This version of df cannot show the space available on unmounted file sys‐ tems,...
Show information about the file system on which each FILE resides, or all file systems by default. df displays the amount of disk space available on the file system containing each file nameargument. If no file name is given, the space available on all currently mounted file systems is show...
df — Use the df command to see the available disk space in each of the partitions in your system. You can just type in df in the command line and you can see each mounted partition and their used/available space in % and in KBs. If you want it shown in megabytes, you can use t...

这个值是/proc/meminfo中Shmem的值buff/cache列显示被 buffer 和 cache 使用的物理内存大小availablev3.3.10中的项。看起来这个值是可以使用的内存,不过(available + used) < total,也就是available < (free + cache + buffers)。而在v3.2.8中(free + cache + buffers)是一般认为的可用内存,既然在新版本中...

Available:也就是剩下的磁盘空间大小; Use%:就是磁盘的使用率啦!如果使用率高达 90% 以上时, 最好需要注意一下了,免得容量不足造成系统问题; Mounted on:就是磁盘挂载的目录所在。 范例一:将系统内的所有特殊文件格式及名称都列出来 image 范例二:将 /etc 下面的可用的磁盘容量以易读的容量格式显示 ...
