To give permission to execute a file you should navigate to file copied location in terminal

by default when you open-up the terminal your terminal location will look some thing like this

george@Area51-HP-Pro-3330-MT ~ $

if you type "pwd"

you can see current directory in the terminal

george@Area51-HP-Pro-3330-MT ~ $ pwd

/home/george                                         <----  currently i have mounted to /home/user

for this tutorial i have copied file in a folder in the desktop so i have to navigate to that directory for eg: my folder name is called "Dashboard"

to navigate that folder i have to type in cd /Desktop/Dashboard

after that type ls so that you can list all files in the terminal

they type following command in the terminal , in my case i am using NVIDIA-Linux-x86_64-375.66.run file as executable this may vary with yours

* Note

sudo = root "super user " permission

chmod = The command name chmod stands for "change mode", and it is used to define the way a file can be accessed.

+x = this will execute a file

./ = if you are using a script .sh or .run you should use this following by the file name

if you use -x instead of +x this will remove file permission

This is will remove permissions
