title: linux bash error: -bash: No such file or directory
body: <p>After I login to Linux every time, it shows :
      -bash: /usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin=/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/xx/bin: No such file or directory</p>
  
  <p>I notice that there is  a '=' in it,  but I don't know why.
  My .bash_profile:</p>
  
  <pre><code># .bash_profile
  
  # Get the aliases and functions
  if [ -f ~/.bashrc ]; then
          . ~/.bashrc
  fi
  
  # User specific environment and startup programs
  
  $PATH=$PATH:$HOME/bin
  
  export PATH
  export JAVA_HOME=/opt/jdk1.8.0_73
  export PATH=$JAVA_HOME/bin:$PATH
  export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
  </code></pre>
  
  <p>I want to set the JAVA environment , and it works ,but after I edit profile,it shows the bash error.
  How could I fix it?</p>
