Hi All,

Thank you RudiC driving me

I resolved my issue with snippet below

Code:
diff $HOME/.bashrc $HOME/temp_alias_compare_file >/dev/null 2>&1
  if [ $? -eq 1 ];then
    diff $HOME/.bashrc $HOME/temp_alias_compare_file | grep 'alias' | grep -v 'showdb' | while read line
         do
            unalias $(echo $line | awk -F"=" '{print $1}' | awk -F"alias" '{print $2}' | sed 's/^ //g')
         done
  fi
. $HOME/.bashrc
