From: Michael F. Stemper (mstemp...)

I wanted to see which LaTeX packages I was using for a particular
project, so I did:

[email protected]$ grep -h "\\usep" *tex | sort | uniq
% \usepackage{array} % for math mode columns in tabular
% \usepackage{graphicx}
% \usepackage{longtable}
% \usepackage{mathrsfs} % for mathscr
% \usepackage{tikz-cd} % for commutative diagrams
\usepackage{amsmath} % for implication and align*
\usepackage{amssymb} % for black-board set names
[email protected]$

However, that showed unused packages as well. So I tried
anchoring my grep to the beginning of the line, and got:

[email protected]$ grep -h "^\\usep" *tex | sort | uniq
[email protected]$

Why isn't this working? What am I overlooking? How
should I have said it?
