In this post we gonna see how to find size of a directory from Terminal. To summarise disk usage of each file, recursively for directories, we can use the following command du [option]... [FILE/Directory]... To get the report in human readable format, along with the overall summary, use du -hs /path/to/directory To find sizes of directories recursively unto a certain depth (e.g.: depth = 2): du -h --max-depth=2 /path/to/directory

Recently I faced problem using maven under a proxy network and by little research, found this solution. Temporary solution : Add the following options along with your maven command -DproxySet=true -DproxyHost=myproxy.com -DproxyPort=3128 For example, to run "mvn package": mvn -DproxySet=true -DproxyHost= my.proxy.host -DproxyPort= 3128 package Permanent solution : To add the proxy settings permanently, goto {M2_HOME}/conf/settings.xml and find the <proxies> section. Un-comment the required sections and configure accordingly. To set proxy without password protection, change it as follows: <proxies>    <proxy>       <id>optional</id>       <active>true</active>       <protocol>http</protocol>       <host> proxy.host.net </host>       <port> 80 </port>  ...

To execute command which is at number 115 in the list, just type !115 It will run the 115th command in the history list. To re-run a recent command that starts with xyz, just ty...
