THC problem

I'm still not getting it sorry  Do I need to be in another directory in the terminal??
 

 

CHMOD is not the same as chmod,
That is, there is no CHMOD command
but there is a chmod command.

first command:

chmod +x checkmask.txt
 
second command

./checkmask.txt eth0

You should be able to copy, paste these into a
terminal window (in the Downloads directory
since that's where downloaded files go)

no difference it now looks like there is no file checkmask.txt.  I tried different spacing too.
 

1. You have to know where you downloaded the file

Note, at least with Firefox, you can specify "Save link as"
so you know both the name of the saved file and where
its been saved.

2. chmod+x is not valid, chmod +x is (note the space between chmod and +x )

cd
press enter

cd Downloads
press enter

>>>>copy the line bellow by left clicking 3 times fast on the line and right click select "copy"<<< right click in terminal and choose "paste"
press enter
