Some useful switches for “du – disk usage”

As we know, du command is used to check the disk usage of files and folders under Linux system. There are a lot of switches available for du among which here I am trying to explain the most common switches used.

As you know, one can easily checks the switches available for du by looking at the man page for du or by executing the command du –help .

Here I am trying to provide some basic guidelines about commonly used switches so that you can use them whenever in need.

Most commonly used form

# du -sch

h -> human readable format.
c -> display a total size usage at the end of result.
s -> display total size of a file or total size of all files in a directory.

Usage:

root@server [/home/abl]# du -s /home/abl
213932 /home/abl
root@server [/home/abl]# du -sh /home/abl
209M /home/abl
root@server [/home/abl]# du -sch /home/abl
209M /home/abl
209M total

Listing all files and directories, switch “a”

# du -ah

a -> this switch displays disk usage of all individual files and directories.

Usage:

root@server [/home/abl/etc]# du -ah /home/abl/etc | tail
0 /home/abl/etc/wis.com/quota
4.0K /home/abl/etc/wis.com
0 /home/abl/etc/ftpquota
0 /home/abl/etc/quota
4.0K /home/abl/etc/cacheid
0 /home/abl/etc/ablo.com/passwd
0 /home/abl/etc/ablo.com/shadow
0 /home/abl/etc/ablo.com/quota
4.0K /home/abl/etc/ablo.com
28K /home/abl/etc

Exclude something from the command output, using –exclude

# du –exclude

-–exclude -> This switch will avoid the particular file name that we have mentioned.
In the below example du -ah avoid files ending with .txt (–exclude=”*.txt”)

 root@server [/home/abl/etc]# du -ah –exclude=”quota” /home/abl/etc | tail
4.0K /home/abl/etc/wis.abl.com
0 /home/abl/etc/wis.com/passwd
0 /home/abl/etc/wis.com/shadow
4.0K /home/abl/etc/wis.com
0 /home/abl/etc/ftpquota
4.0K /home/abl/etc/cacheid
0 /home/abl/etc/abl.com/passwd
0 /home/abl/etc/ablogsite.com/shadow
4.0K /home/abl/etc/ablogsite.com
28K /home/abl/etc

Display modification time of files/folders, using –time

# du –time

–time ->This option shows the modification date and time of the file/directories.

root@server [/home/user/folder]# du -sch –time *
1.8M    2017-05-19 00:32    Folder 1
248M    2017-05-06 07:35   Folder 2
40K       2016-12-15 15:05   Folder 3
32K       2017-04-27 15:46   File.pdf
250M    2017-05-19 00:32    total

This switches should help you get the disk usage of the files in any directory.
