Linux: Find Out Directory Size Command



To get the size of a Directory in Linux, use du command. du command is used to find the file space usage & summarize disk usage of each file/directory.

To find the size of /usr directory:

  du /usr
OR

 Pass -s option to see the total disk space summary & -h option for human readable format.

  du -sh /usr


We can also list the contents of the directory (whether file or directory) with size:-

du -sh /usr/*

Sample output:
[root@myserver ~]# du -sh /usr/*
71M     /usr/bin
8.0K    /usr/etc
8.0K    /usr/games
87M     /usr/include
122M    /usr/java
1.8M    /usr/kerberos
535M    /usr/lib
199M    /usr/lib64
12M     /usr/libexec
212M    /usr/local
17M     /usr/sbin
563M    /usr/share
57M     /usr/src
4.0K    /usr/tmp
48M     /usr/X11R6

CentOS / Redhat : Configure CentOS as a Software Router with two interfaces

Linux can be easily configured to share an internet connection using iptables. All you need to have is, two network interface cards as follows: a) Your internal (LAN) network connected via eth0 with static ip address 192.168.0.1 b) Your external WAN) network is connected via eth1 with static ip address 10.10.10.1  ( public IP provided by ISP ) Please note that interface eth1 may have public IP address or IP assigned by ISP. eth1 may be connected to a dedicated DSL / ADSL / WAN / Cable router: Step # 1: Enable Packet Forwarding Login as the root user. Open /etc/sysctl.conf file # vi /etc/sysctl.conf Add the following line to enable packet forwarding for IPv4: net.ipv4.conf.default.forwarding=1 Save and close the file. Restart networking: # service network restart Step # 2: Enable IP masquerading In Linux networking, Network Address Translation (NAT) or Network Masquerading (IP Masquerading) is a technique of transceivin

Virtual Box and Alt/Tab Keys

I use virtual box for all my testing activities. It comes too often that I have a virtual box VM window open & I want to switch to my host machine to see some stuff like tutorials etc.. If you press the alt+tab combination it just works inside the VM & doesn't switches to host machine. In these scenarios you can press the host key once ( not hold it ) & then whatever you press goes to host machine. So in general where host key is the default Right Ctrl, just press Right Ctrl once & now press the alt+tab & it will switch you out to host machine. This is really helpful when you have the VM windows open or you're working on seamless mode. Hope it help others too.

Set date and time in Linux

There are few ways to set the date and time on Linux command line. In order to do this, you must login as root and execute the following methods as follow: For you to remember the syntax, issue the command “date” first [root@linuxtechtips ~]# date Mon Aug 20 18:30:29 SGT 2012 Let say you want to change it to Sept 6, 2012, 3pm, just follow the pattern above [root@linuxtechtips ~]# date 090615002012 Thu Sep  6 15:00:00 SGT 2012 where as: 09 = month (September) 06 = day 15 = hour 00 = min 2012 = year Now it’s set, as simple as that: [root@linuxtechtips ~]# date Thu Sep  6 15:00:01 SGT 2012 Another example, you want it to change to 20th of December, 2012, 10:45pm [root@linuxtechtips ~]# date 122022452012 Thu Dec 20 22:45:00 SGT 2012 Viola!!! [root@linuxtechtips ~]# date Thu Dec 20 22:45:03 SGT 2012 Now if you want to challenge yourself, then you can use this as well: Using our example date above, use the date comman
