Simple Linux/Coedit install problem...

[WhatMeWorry via Digitalmars-d-ide]

I'm just learning Linux so this might be really stupid, but

Following the steps at 
https://github.com/BBasile/Coedit/wiki#detailed-setup-procedure

The content must be extracted and executed:

Linux, all users, in a console cd to the file location and type
sudo .\coedit.<version>.<platform>.setup.

generic at generic:~/Downloads$ ls -al   // after extracting...
total 39028
drwxr-xr-x  2 gen generic     4096 Jun 19 13:19 .
drwxr-xr-x 18 gen generic     4096 Jun 19 12:52 ..
-rwxr-xr-x  1 gen generic 32282733 May 27 00:48 
coedit.2update6.linux64.setup
-rw-rw-r--  1 gen generic  7666476 Jun 19 13:16 
coedit.2update6.linux64.setup.zip

But for the life of me I can't get the

sudo .\coedit.<version>.<platform>.setup    // to work.

generic at generic:~/Downloads$ sudo .\coedit.2update6.linux64.setup

[sudo] password for generic: (enter my password)

sudo: .coedit.2update6.linux64.setup: command not found


My terminal (pwd) is sitting the the very directory at 
coedit...setup file?
Thanks.
