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

Shell Script: Find Number Of Arguments Passed

Many times , when we create shell scripts we try to do repetitive tasks through functions. Some functions take arguments & we have to check the no. of arguments that are passed to it. Each bash shell function has the following set of shell variables: [a] All function parameters or arguments can be accessed via  $1, $2, $3,..., $N . [b]  $*  or  $@  holds all parameters or arguments passed to the function. [c]  $#  holds the number of positional parameters passed to the function. [d] An array variable called  FUNCNAME  ontains the names of all shell functions currently in the execution call stack. Example Create a shell script as follows: #!/bin/bash # Purpose: Demo bash function # -----------------------------   ## Define a function called test() test(){   echo "Function name:  ${FUNCNAME}"   echo "The number of positional parameter : $#"   echo "All parameters or arguments passed to the function: '$@'"   e

AMD Radeon™ HD 7670M on Ubuntu 12.04

Update:   Recently I install kubuntu 13.10 and there is no problem with graphics. It just works  fine out of the box. I've seen many blog posts on how to make AMD HD7670M work on Ubuntu 12.04, specially when its in switchable graphics board like Dell Inspiron 15R 5520. I tried many things to make it work so that I could use the cinnamon desktop on ubuntu & other things too.. But to my surprise even the drivers from AMD site didn't work. Then I tried a combination of those blog posts I read & somehow I became successful in running the full graphics including compiz settings inside My Ubuntu Machine. Following are the steps I followed & it worked... 1. Create a backup of your xorg configuration file: sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.BAK 2. Remove/purge current fglrx and fglrx-amdcccle : sudo apt-get remove --purge fglrx* 3. Install the driver: sudo apt-get install fglrx fglrx-amdcccle 4. Install additional

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
