I create a command,

\newcommand{\cmd}{b}

but when I use this command

a\cmd{}c

What I get is

a b c

but what I want is

abc

How can I remove two blanks?

Welcome to TeX.SX! With that definition and usage you'll get the second instance, not the first. Probably you should show your real case. – egreg Jul 04 '12 at 14:51
A complete code is necessary because like egreg wrote, you should show your real case. Perhaps you want a b c ? – Alain Matthes Jul 04 '12 at 16:35

if you never want a space before or after the contents of the command, define it as \newcommand{\cmd}{\unskip b\ignorespaces}. – barbara beeton Jul 04 '12 at 17:07

If there are line breaks in your actual command definition, you need to add comment signs, see Why the end-of-line % in macro definitions?. – Caramdir Jul 04 '12 at 17:45

You sure your definition does not contain spaces as in \newcommand{\cmd}{ b }. This would yield the result that you describe that you are getting. – Peter Grill Jul 04 '12 at 17:49
