Can't run a copied program

I copied a program that had spaces and stuff that made it difficult to write in the terminal.
I simply copied it to pss (sudo cp [appname] [pss])

But when I write pss in the terminal, it says that
Command 'pss' not found, but there are 16 similar ones.

There is something called pss in that directory now..

There are actually no way to delete a post, so everyone, ignore this, I'm not sure the file is a program anyway..
Check the file attributes by typing 'ls -l' in the directory. If it's an executable, it'll have an 'x' in the attributes "-rwxr-xr-x 1 carl carl 16872 Jan 13 05:42 firefox". In this example, rwXr-Xr-X, the means that it's executable by the owner, group, and other. In this example there are no X''s, "-rw-r--r-- 1 carl carl 1449 Jan 13 05:42 firefox.sig", it's not an executable file.

If you find that your file is executable, but you're still having trouble, try launching it using ./ as a prefix, './firefox'. Sometimes your current directory is not in your path so you have to specify it.
Thx alot, the command ls -l -a gave me the information I needed (-a for hidden files)

Isn't there anyway to make so ls uses -l -a by default?
yes, the -a shows all. Since you said it was supposed to be an executable, I assumed it wouldn't be hidden :). There may be a way to make it use some flag by default. I've never tried in my 12 years of using Linux/Unix. I always just type out the full 'ls -al' when I need it.
I'm accessing the Linux view vnc by phone, so all ways to shorten commands are good.

But, now I listed the directory, and it is an executable file, I'm updating the original question with a screenshot.
