This article is about how the LINUX system uses commands to clean up disk space. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

1. Scan and compare the important file systems regularly, and analyze which files are read and written frequently.

# IS-IR/home >; files.txt

# diff filesold.txt files.txt

By analyzing the growth of the predicted space, we can also consider compressing the files that read and write infrequently to reduce the space occupied.

2. View the inodes consumption of the spatial file system

# df-i/home

If there is still a large number of inpde available, it means that large files take up space, otherwise thieves may take up a large number of small files.

3. Find out the directory that takes up more space.

View the space occupied by / home

# du-hs/home

View / home occupies more than 1000m space

# du/awk'$1 >; 2000'

4. Find out the files that take up more space.

# find/home-size + 2000K

5. Find out the recently modified or created files

First TOUCH a file of the time you want is as follows

# TOUCH-t 08190800 test

# find/home-newer test-print

Delete Log

# rm-rf/var/log/*

6. Connect the partition

In a partition with space, make a connection to the partition that has no space.

# in-s/home/use/home

7. Find a process that consumes a lot of space

According to different applications, find out the corresponding process and analyze the reasons.
