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.
