Motivation

To share useful aliases which saves time to go to browser. Also helps to write scripts.

URL Encode and Decode

alias urldecode='python -c "import sys, urllib as ul; print ul.unquote_plus(sys.argv[1])"'
alias urlencode='python -c "import sys, urllib as ul; print ul.quote_plus(sys.argv[1])"'

Example:

mahendran@mm-lab mahendran % alias urldecode='python -c "import sys, urllib as ul; print ul.unquote_plus(sys.argv[1])"'
alias urlencode='python -c "import sys, urllib as ul; print ul.quote_plus(sys.argv[1])"'
mahendran@mm-lab mahendran % urlencode https://test@somethi%now                                                        
https%3A%2F%2Ftest%40somethi%25now
mahendran@mm-lab mahendran % urldecode https%3A%2F%2Ftest%40somethi%25now
https://test@somethi%now
mahendran@mm-lab mahendran %

                unset JAVA_HOME
                version=$1
                export JAVA_HOME=$(/usr/libexec/java_home -v"$version");
