A better instruction is follows

## Installing Eclipse the hard way

Usually, extracting the Eclipse Luno into your home directory shall be enough to allow you to work with it. But sometimes the package requires to be installed into "/opt" and refuses to work properly or to work at all when installed elsewhere. In that case (if you are not a Linux guru) it is often easier to just reinstall the OS from scratch (remember to back up your data first). However sometimes reinstallation of the OS is not feasible.

The following workflow was used to install Eclipse Luno on one such misbehaving system, however it is not guaranteed that this type of misbehavior will be exactly the same in your case so your mileage may vary. These instructions assume you already have the JDK and Maven packages installed and the installation package downloaded as described in the "easy way" installation instructions.

1. Open a terminal (Ctrl-Alt-T) and switch it to root permissions by entering:

`$ sudo su`

1. Extract the Eclipse installation package into /opt:

`# cd /opt`

`# sudo tar -xzvf`

`<`

`path_to_the_downloaded_package`

`>`

1. Increase the memory for the Eclipse installation by modifying the

[/opt/eclipse/eclipse.ini](http://wiki.eclipse.org/Eclipse.ini)

file. See the "easy way" for instructions.

Create a startup script for the Eclipse:

`# cd /usr/local/bin`

`# echo 'ECLIPSE=/opt/eclipse/eclipse'`

`>`

`eclipse`

`# echo 'exec $ECLIPSE "$@"'`

`>`

`>`

`eclipse`

`# chmod +x eclipse`

1. Now exit the root mode and start the installed eclipse:

   `# exit`

   `$ eclipse`

\*\*\*

We can simply copy eclipse folder to /opt, then

open`~/.bashrc`with your favourite editor and add the following lines to the end of the file:

```
if [ -d "/opt/eclipse" ] ; then
    PATH="/opt/eclipse:$PATH"
fi
```

Close and open the terminal.
