Then you have a new Folder called tdxminer.... open it. In zhis folder you need a .sh-file to use the miner too, there is no sh-file within the package. a SH-File is like a .BAT-File in Windows, you can edit it with Notepad or something like that.

So you can create a simple Doc, right Mouseclick, new document
In that you wrote ./tdxminer -a lyra2z -o stratum+tcp://eu1.fairmine.pro:4553 -u se345rwijhoseifglerkhfh -p c=BTC

-a is for th Algorithm you want to mine. -o is for the pool. -u is for your Walletadress. -p is for the Poolpasswort, if needed, mostly its only x. c is for the Short of the Coin, e.j. Bitcoin is BTC.

Save the file ,thats it.

Now you can doubleclick on the SH-File, Ubuntu ask what to do with that file-type, choose that Ubuntu schould use it as executable file. Now it will start as program everytime you click on it. Sometimes Ubuntu dont know a sh-file. Then open a Terminal in that folder, type chmod a+x FILENAMe.sh and press Enter. Then doubleclick the sh-file again.
