why is "export PATH" displayed in terminal as a title?

  • 772

I have a long time using Ubuntu, probably 3 or 4 years, I've never had the need to "export a path".

Now, I was installing Xilinx ISE 14.7 in Kubuntu 14.04 Trusty Tahr LTS following a tutorial, at some point the tutorial advised to create a PATH (I don't even know what it is, but I guess that is like a link or shorcut to launch the program easily).

The tutorial advise to run echo "PATH=\$PATH:/opt/Xilinx/14.7/ISE_DS/ISE/bin/lin64/" >> ~/.bashrc echo "export PATH" >> ~/.bashrc, now everytime I open a terminal it displays:

Terminal

Triple Question here:

  • How can I erase that undesired title there?
  • Is the path a shortcut to execute a program?
  • If so, how can I successfully do it in this case?
command-line

    Likely what happened is you concatenated two separate echo commands on a single line, causing the second command (complete with the echo) to get written to the file (instead of the output of the command).

    • Open your ~/.bashrc file in any text editor, and replace the line echo export PATH by plain export PATH
    • It's a list of directories that are searched (in order) for the command, rather than a direct shortcut to it

    • Put the commands on separate lines next time, like

      echo "PATH=\$PATH:/opt/Xilinx/14.7/ISE_DS/ISE/bin/lin64/" >> ~/.bashrc

      then

      echo "export PATH" >> ~/.bashrc
