Linux⽂件查神器命令find：查⼤于或者⼩于某⼤⼩的⽂件Linux, 刚好有个需求，就是查少于1K的⽂件，然后对这些⽂件进⾏删除操作.
命令如下:
ind . -type f -name "*.log" -size -1k | xargs rm -rf

Find Files Bigger Or Smaller Than X Size
Using find command, we can also easily find files bigger or smaller than given size.
For instance, to find files that are bigger than 4GB in a directory, just enter:
$ find . -type f -size +4G
Sample output from my system:

As you can see, I have some files with size bigger than 4GiB. Here, the dot (.) indicates the current directory.
To search for files bigger than 4 GiB in the entire filesystem, run:
$ find / -type f -size +4G
To know files bigger than X size in a specific directory, replace the dot (.) in the above command with the directory path like below.
$ find Downloads/ -type f -size +4G
The above command find files bigger than 4 GiB in Downloads directory.
Similarly, to find the files which are smaller than X size, for example 4GiB, use the following command:
$ find . -type f -size -4G
You can use size switch for other formats, such as
`c' for bytes
'w' for two-byte words
`k' for Kilobytes
`M' for Megabytes
`G' for Gigabytes
For example, to find files which are bigger than 4MB, use the following command:
$ find . -type f -size +4M
To find files smaller than 4MB, use this command:
$ find . -type f -size -4M
You might wonder how to find files between a certain size. For instance, you can find files between 30MB and 40MB using the following
command:
$ find -size +30M -size -40M
To find files of exact size, for example 30MB, run:
$ find -size 30M
For more details, refer man pages.find查命令的使用
$ man find
Update:
As one of the reader mentioned in the comment section below, the find command can also display a long listing of all the files it finds by using the -exec switch. The command below will find all of the files between 30M and 40M, and display a long listing of each file.
$ find . -type f -size +30M -size -40M -exec ls -l {} +
