latex resizebox in a minipage for tabular with a caption

We can put tabular to resizebox to easily resize a table in latex. 

If it's in a minipage environment, we might need caption package to add captions. 

see http://tex.stackexchange.com/questions/124346/latex-error-not-in-outer-par-mode

backref put page number in the reference list

\usepackage[pagebackref]{hyperref}

obtain a figure file list from a tex file using grep and sed: new version

#!/bin/bash 

# to get a list of pdf files included in a tex file 

# echo "Usage: $0 {file.name}" 

# echo "Processing file $1"

EXPECTED_ARGS=1

E_BADARGS=65

if [ $# -ne $EXPECTED_ARGS ]

then

  echo "Usage: `basename $0` {tex.file}"

  exit $E_BADARGS

fi

tmpfile=`mktemp -p . exttmp.XXXX`

grep includegraphics $1 > $tmpfile

# sed -e 's/includegraphics/  /' -e 's/[\\{}]//g' -e 's/\[.*\]//g' -e 's/[^ ]\+//' -e 's/^ \+//' < $tmpfile 

# this one is much better than the above 

sed -e 's/.*{\(.*\.pdf\)}.*/\1/' < $tmpfile

if [ -f "$tmpfile" ]

then

    rm "$tmpfile"

fi

tmpfile=`mktemp -p . exttmp.XXXX`

grep includegraphics $1 > $tmpfile

sed -e 's/includegraphics/  /' -e 's/[\\{}]//g' -e 's/\[.*\]//g' -e 's/[^ ]\+//' -e 's/^ \+//' < $tmpfile

if [ -f "$tmpfile" ]

then

    rm "$tmpfile"

fi

#

# the includegraphics must be at the same line with the pdf or other figure files included.

beamer bullets for table of contents

%\setbeamertemplate{sections/subsections in toc}[ball]
\setbeamertemplate{subsection in toc}[ball]
%ref: beamer class user guide

beamer is not good in the sense that it took me quite a long to figure
out how to put some bullets in the table of contents.

beamer installation place on ubuntu

/usr/share/texmf/tex/latex/beamer

it might be help when we need to know where beamer and other classes
files are located.

and use
texhash
mktexlsr

to remake the indices for texlive
