copy/delete word under cursor in Vim
yw / byw

Assuming that the cursor is at the first character of the word simply do this in command mode:
     yw
y is for yank and w is for word.

Other ways of doing the same thing which are not as efficient:
     vey
the v starts visual select mode. e tells vim to move to end of word. y yanks or copies the word. to delete replace y with x.

# General remarks
# * Executables should have no extension (strongly preferred) or a .sh extension. 
# * Libraries must have a .sh extension and should not be executable
