In linux, it is easy to simply find the file and directory size # the size of the specified directory or file is displayed in an easy-to-read format, the-s option specifies that the du-sh [dirname | filename] of each subdirectory or file is not displayed in detail for the directory. for example, the size of the current directory is as follows: Copy the code du-sh as follows. when
In linux, it is easy to find files and directories.
# The size of the specified directory or file is displayed in a readable format. the-s option specifies that the size of each subdirectory or file is not displayed in detail for the directory.
Du-sh [dirname | filename]
For example:
Current Directory size:
The code is as follows:
Du-sh.
Size of files or directories in the current directory:
The code is as follows:
Du-sh *
Display the first 10 most occupied files or directories:
The code is as follows:
Du-s * | sort-nr | head
*-H the readable format shows the size of the specified directory or file
* The-s option specifies that the size of each subdirectory or file is not displayed in detail for the directory.
How do I find all the large files in the directory?
The find command in linux is used to find files. man find can be used to find files that are omnipotent. Therefore, simply find the file according to the file size. Search for the size from man find. the following information is displayed:
-Size n [cwbkMG]
File uses n units of space. The following suffixes can be used:
B for 512-byte blocks (this is the default if no suffix is used)
C for bytes
W for two-byte words
K for Kilobytes (units of 1024 bytes)
M for Megabytes (units of 1048576 bytes)
G for Gigabytes (units of 1073741824 bytes)
Note: The default unit is B, and it represents 512 bytes. Therefore, 2 indicates 1 K, and 1 m indicates 2048. if you do not want to convert it yourself, you can use other units, such as c, K, and M

1) syntax for RedHat/CentOS/Fedora Linux
The code is as follows:
Find {/path/to/directory/}-type f-size + {size-in-kb} k-exec ls-lh {}; | awk '{print $9 ":" $5 }'
Instance:
Search for files larger than 50 MB in the current directory
The code is as follows:
$ Find.-type f-size + 50000 k-exec ls-lh {}; | awk '{print $9 ":" $5 }'
Search for files whose directory/var/log is greater than MB
The code is as follows:
# Find/var/log-type f-size + 100000 k-exec ls-lh {}; | awk '{print $9 ":" $5 }'
2) syntax for Debian/Ubuntu Linux
Find {/path/to/directory}-type f-size + {file-size-in-kb} k-exec ls-lh {}; | awk '{print $8 ":" $5 }'
Instance:
Search for files larger than 10 MB in the current directory
The code is as follows:
$ Find.-type f-size + 10000 k-exec ls-lh {}; | awk '{print $8 ":" $5 }'
Sample output:
./. Kde/share/apps/akregator/Archive/http ___ blogs.msdn.com _ MainFeed. aspx? Type = AllBlogs. mk4: 91 M
./Out/out.tar.gz: 828 M
./. Cache/tracker/file-meta.db: 101 M
./Ubuntu-8.04-desktop-i386.iso: 700 M
./Vivek/out/mp3/Eric: 230 M
List files with a file size smaller than B in the home directory:
The code is as follows:
$ Find $ HOME-size-500b
OR
$ Find ~ -Size-500b
List files with a size of 20 512-byte blocks in the root directory:
The code is as follows:
# Find/-size 20
