Free up disk space and make your Linux system run more smoothly

As we perform various operations in Linux systems, the disk space on our computers has been decreasing. When our hard disk space becomes less and less, we often encounter problems such as slower file reading and writing speeds and slower system response. These problems will affect our work efficiency, so it is particularly important to free up hard disk space in a timely manner. In this article, we will introduce how to find and delete unnecessary files and directories to free up disk space in Linux systems.

Everyone comes into contact with files without spaces a lot in their daily work. In this way, the deletion operation is relatively simple. But sometimes we come into contact with files with spaces. How should we delete this kind of file?

First we demonstrate the find command combined with the xargs command to delete files without spaces

[root@ELK-chaofeng test]# touch 1.txt 2.txt
[root@ELK-chaofeng test]# ls
1.txt 2.txt
[root@ELK-chaofeng test]# find . -type f | xargs
./1.txt ./2.txt
[root@ELK-chaofeng test]# find . -type f | xargs rm -rf
[root@ELK-chaofeng test]# ls
[root@ELK-chaofeng test]#

Next we demonstrate deleting files with spaces

[root@ELK-chaofeng test]# touch 1.txt 2.txt '1 2.txt'
[root@ELK-chaofeng test]# ls
1 2.txt 1.txt 2.txt
[root@ELK-chaofeng test]# ll
total 0
-rw-r--r-- 1 root root 0 Feb 14 12:24 1 2.txt
-rw-r--r-- 1 root root 0 Feb 14 12:24 1.txt
-rw-r--r-- 1 root root 0 Feb 14 12:24 2.txt
[root@ELK-chaofeng test]# find . -type f -print0 | xargs -0 rm -rf
[root@ELK-chaofeng test]# ls

The above parameter -print0, compared with the default -print, the output sequence is not separated by spaces, but by null characters. xargs also has a parameter -0, which can accept input streams separated by nulls instead of spaces.

Disk space is an issue that every computer needs to pay attention to, and in Linux systems, reasonable management of disk space is even more imperative. This article helps users free up valuable disk space and improve system operating efficiency by introducing how to use some simple commands and tools to find and delete unnecessary files and directories. I hope that the introduction in this article will help you better manage your hard drive space and make your Linux system smoother and more efficient.
