title: Why I can not start my tomcat from command line?
body: <p>I downloaded tomcat version 7.0.16 binary distributions core tar.gz from tomcat's official website to my ubuntu machine, then extracted the downloaded file. </p>
  
  <p>Then, I used terminal command to specify the path to <code>~/apache-tomcat-7.0.16/bin</code>$ , then I entered <code>startup</code> command, but I have got '<strong>startup: command not found</strong>' message, but when I used linux command <code>ls</code>, there were <strong><em>startup.bat</em></strong> and <strong><em>startup.sh</em></strong> under <em>bin/</em>.</p>
  
  <p>I also tried to enter startup.bat and startup.sh, the same message returned. Why I can not start my tomcat v7 from ubuntu terminal window??</p>
