The ls<\/code> command is most popular and very useful command for listing the content of directories. In this article, we will explain how to use  ls<\/code> sort option to list directory content by size.<\/p>\n\n\n\n

1) List Files in the directory by size (Sorting)<\/h2>\n\n\n\n

To list a content of a specific directory with size sorting, we will use -lS<\/code> options with ls<\/code> command. It will display files with the highest size at the top.<\/p>\n\n\n\n

$ ls -lS \/run<\/code><\/pre>\n\n\n\n
output total 24 -rw-rw-r--. 1 root utmp 2304 Sep 8 14:58 utmp drwxr-xr-x. 16 root root 400 Aug 21 13:18 systemd drwxr-xr-x. 7 root root 160 Aug 26 14:59 udev drwxr-xr-x. 4 root root 100 Aug 21 13:18 initramfs drwxr-xr-x. 4 root root 100 Sep 8 03:31 lock drwxr-xr-x. 3 root root 100 Aug 21 13:18 NetworkManager drwxr-xr-x. 2 root root 60 Aug 21 13:18 dbus drwxr-xr-x. 3 root root 60 Aug 21 13:18 log drwxr-xr-x. 2 root root 40 Aug 21 13:18 console drwxr-xr-x. 2 root root 40 Aug 21 13:18 faillock drwxr-x---. 2 root root 40 Aug 21 13:18 firewalld To list with file size but it wont be sorted, we will use -s option with ls command.<\/code><\/pre>\n\n\n\n
$ ls -s<\/code><\/pre>\n\n\n\n
2) List Files with size (Reverse sorting)<\/h2>\n\n\n\n
To list the content of a specific directory with size reverse sorting (ie lowest size files be at top), we will use -lSr<\/code> options with ls<\/code> command.<\/p>\n\n\n\n
$ ls -lSr \/run<\/code><\/pre>\n\n\n\n
output total 24 -rw-------. 1 root root 0 Aug 21 13:18 xtables.lock -rw-------. 1 root root 3 Aug 21 13:18 syslogd.pid -rw-r--r--. 1 root root 4 Aug 21 13:18 sshd.pid -rw-r--r--. 1 root root 4 Aug 21 13:18 auditd.pid drwxr-xr-x. 2 root root 40 Aug 21 13:18 setrans<\/code><\/pre>\n\n\n\n
3) Sort output and print sizes in human readable format (e.g., 1K 48M 1G)<\/h2>\n\n\n\n
To sort output and print sizes in human readable format, we will use -h<\/code> option with ls<\/code> command.<\/p>\n\n\n\n
$ ls -lSh<\/code><\/pre>\n\n\n\n
output total 1.3M -rw-r--r--. 1 root root 1.1M Aug 26 15:45 GeoIP-1.5.0-11.el7.x86_64.rpm -rw-r--r--. 1 root root 177K Aug 26 15:29 index.html drwxr-xr-x. 2 root root 4.0K Sep 8 13:32 apache2 drwxr-xr-x. 2 root root 4.0K Sep 8 13:31 Desktop drwxr-xr-x. 2 root root 4.0K Sep 8 13:32 Documents drwxr-xr-x. 2 root root 4.0K Sep 8 13:32 Downloads drwxr-xr-x. 2 root root 4.0K Sep 8 13:32 Pictures .......<\/code><\/pre>\n\n\n\n
Also, we can print sizes in human readable format for specific extention.<\/p>\n\n\n\n
ls -l -S -h *.mp3<\/code><\/pre>\n\n\n\n
ls -l -S -h ~\/Downloads\/*.mp4 | more<\/code><\/pre>\n\n\n\n
Few Basic Tips<\/h2>\n\n\n\n
4) List in alphabetical sorting<\/h2>\n\n\n\n
To list a content of a specific directory with alphabetical sorting, we will use ls<\/code> command only without option, because alphabetical sorting is the default.<\/p>\n\n\n\n
$ ls<\/code><\/pre>\n\n\n\n
output anaconda-ks.cfg Desktop echo.txt index.html Pictures smart.txt apache2 Documents f.txt nano.txt printf.txt vim.txt cat.txt Downloads GeoIP-1.5.0-11.el7.x86_64.rpm original-ks.cfg smart.docx vi.txt<\/code><\/pre>\n\n\n\n
To list a content of a specific directory with details, add the path of the directory.<\/p>\n\n\n\n
$ ls -l \/run<\/code><\/pre>\n\n\n\n
output total 24 -rw-r--r--. 1 root root 4 Aug 21 13:18 auditd.pid drwxr-xr-x. 2 root root 40 Aug 21 13:18 console -rw-r--r--. 1 root root 4 Aug 21 13:18 crond.pid ----------. 1 root root 0 Aug 21 13:18 cron.reboot drwxr-xr-x. 2 root root 60 Aug 21 13:18 dbus -rw-r--r--. 1 root root 4 Sep 9 08:17 dhclient-eth0.pid -rw-------. 1 root root 0 Aug 21 13:18 ebtables.lock drwxr-xr-x. 2 root root 40 Aug 21 13:18 faillock drwxr-x---. 2 root root 40 Aug 21 13:18 firewalld ..........<\/code><\/pre>\n\n\n\n
5) List in alphabetical reverse sorting<\/h2>\n\n\n\n
To list a content of a specific directory with details upon alphabetical reverse sorting, we will use -lr<\/code> options with ls<\/code> command.<\/p>\n\n\n\n
$ ls -lr \/run<\/code><\/pre>\n\n\n\n
output total 24 -rw-------. 1 root root 0 Aug 21 13:18 xtables.lock -rw-rw-r--. 1 root utmp 2304 Sep 8 14:58 utmp drwxr-xr-x. 3 root root 60 Sep 7 23:11 user drwxr-xr-x. 7 root root 160 Aug 26 14:59 udev drwxr-xr-x. 2 root root 60 Aug 21 13:18 tuned drwxr-xr-x. 2 root root 60 Aug 21 13:18 tmpfiles.d drwxr-xr-x. 16 root root 400 Aug 21 13:18 systemd -rw-------. 1 root root 3 Aug 21 13:18 syslogd.pid drwx--x--x. 3 root root 60 Aug 21 13:18 sudo -rw-r--r--. 1 root root 4 Aug 21 13:18 sshd.pid drwxr-xr-x. 2 root root 40 Aug 21 13:18 setrans drwxr-xr-x. 2 root root 40 Aug 21 13:18 sepermit drwxr-xr-x. 2 root root 40 Aug 21 13:18 plymouth .......<\/code><\/pre>\n\n\n\n
6) List hidden content of the directory in alphabetical sorting<\/h2>\n\n\n\n
To list hidden contents of specific directory, we will use -a<\/code> or --all<\/code> options with ls<\/code> command.<\/p>\n\n\n\n
$ ls -a \/etc<\/code><\/pre>\n\n\n\n
 output . default gss logrotate.d pm rsyslog.conf sysctl.d .. depmod.d host.conf machine-id polkit-1 rsyslog.d systemd adjtime dhcp hostname magic popt.d rwtab system-release aliases DIR_COLORS hosts makedumpfile.conf.sample postfix rwtab.d system-release-cpe ........<\/code><\/pre>\n\n\n\n
7) List files in alphabetical sorting<\/h2>\n\n\n\n
To list a content of the specified directory with details, such as the file permissions, the number of links, owner\u2019s name and group owner, file size, time of last modification and the file\/directory name, we will use -l<\/code> option with ls<\/code> command.<\/p>\n\n\n\n
$ ls -l \/run<\/code><\/pre>\n\n\n\n
output total 24 -rw-r--r--. 1 root root 4 Aug 21 13:18 auditd.pid drwxr-xr-x. 2 root root 40 Aug 21 13:18 console -rw-r--r--. 1 root root 4 Aug 21 13:18 crond.pid ----------. 1 root root 0 Aug 21 13:18 cron.reboot drwxr-xr-x. 2 root root 60 Aug 21 13:18 dbus -rw-r--r--. 1 root root 4 Sep 8 12:41 dhclient-eth0.pid -rw-------. 1 root root 0 Aug 21 13:18 ebtables.lock drwxr-xr-x. 2 root root 40 Aug 21 13:18 faillock drwxr-x---. 2 root root 40 Aug 21 13:18 firewalld drwxr-xr-x. 4 root root 100 Aug 21 13:18 initramfs drwxr-xr-x. 4 root root 100 Sep 8 03:31 lock drwxr-xr-x. 3 root root 60 Aug 21 13:18 log ........ <\/code><\/pre>\n\n\n\n
You can also user dir<\/code> command to list files, dir -S<\/code> will sort by size. Thanks for reading my article and please leave your comments.<\/p>\n","protected":false},"excerpt":{"rendered":"
