Now type from the terminal prompt followed by Enter:

Make sure that the ‘tar.gz’ full filename is typed exactly as the name of the downloaded distrubution. Don’t make any mistakes here! So the example above might not correspond with your file name.

Now we have to make Java work, we do this by typing this from the terminal prompt:

Again, the name after ‘JAVA_HOME=’ might not correspond with your installed Java. To make sure you have the right one, type:

You will find the name next to your ‘tar.gz’ file. You can also delete the ‘tar.gz’ file to save space.

Step 3: Install Sencha Cmd

Before we do the final step I would give again some critics to Sencha Inc. for not having a proper installation manual for Sencha Cmd for Linux on their website. “Half work done counts as no work done”. Ok, let’s do the last bit.

First download Sencha Cmd from here: link

Save the ‘zip’ file in your default Downloads location. If you don’t have an ‘unzip’ installed in Debian Jessie, you can install ‘Ark’ with the Synaptic Package Manager. After that said, you unpack the Sencha Cmd ‘zip’ file. You can do this in the same Downloads folder. It will unpack a file with the .sh extension.

Now go to your terminal prompt and type:

Now it will install Sencha Cmd. You will get an warning complaining:

You can ignore this.

Finally add Sench Cmd to your PATH. Type this from your terminal prompt:

Make sure that the Sencha version in the PATH corresponds with the one you just installed. Simply type:

Now it will show you the version you have installed.

If everything has gone well you can now go to your Sencha Ext JS or Touch application folder and type something like “Sencha app watch” or any other Sencha Cmd instruction.
