df unix

Why is the use of Du and DF to view disk capacity inconsistencies, whether there are bugs or disk fragments, or which result should prevail. In fact, the values of the two commands are inconsistent due to differences in implementation of DU and DF commands, rather than failures.[Root@www ~]# Du-sh/home4.7g/home[Root@www ~]# df-h/homeFileSystem Size Used Avail use

I previously wrote a system to monitor the remaining space on the disk script, today it sent me to the police, so I log on to the server to view, the results found that DF and du looked out of the results are different, du looked out of the "actual use of space" is much smaller than the DF found in the use of space, which is why? Is there some space hidden?Finally, the power of the internet to solve the "st

The following describes the 60 required Linux commands that must be mastered by new users.

The difference between Du and DF:Du statistics File size addition, DF statistic block usage, if there is a process in the open a large file, the large file directly by RM or MV dropped, then du will update the statistical value, DF will not update the statistics, or think that the space is not released. Until the process of opening the large file was killed. The problem we encountered was that we periodical

Detailed DF command usage A: displays the disk usage of all file systems and partitions.I: displays the I-nodes usage.K: The size is represented by K (default)T: displays the disk usage of all partitions in a file system.X: displays the disk usage of all partitions of a file system.T: displays the file system name of each partition.Common commands: DF-Hi Operation DetailsThe reference command

In Linux, check the folder size, disk space remaining (du/df), and dudf.1. Introduction View the directory size in du, and view the disk usage in df.2. du Disk usage(1) Basic functions Recursively view the size of all files in a folder(2) common parameters: -H,-human-readable Display dimensions in a readable manner (for example, 1 K 234 M 2G) -S,-summarize only calculates the total usage of each parameter

Questions :Using the DF command to view, a partition usage has reached 100%, but with the du command to count the partition, it is found that the remaining 10G of the partition space is available. Instance:Analysis: If a file is deleted when it is open, the system will still assume that the file still exists. So DF will still be when these files are still present and included in the statistics.Solve： grep

When the size of the disk exceeds the standard, there will be alarm prompts, if you know the DF and du command is a very wise choice.DF can view the first-level folder size, usage scale, file system and its hang-in points, but there is nothing to file. Du can view the size of files and folders.Brief introductionthe DF command can show the available space and usage for all current file systems[Email protecte

There are very many people who say. There is a lot of knowledge on the Internet, why do you have to repeat these things in your blog?What I want to say is that what other people write is something that others understand. At the same time is the summary of the learning process for others, for themselves. Write their own blog The most basic purpose is to record their own learning process, the same time on their own learning things to summarize, when after a period of time to look back. I have expe
