Code Snippets/sed

To change a latex file from having (\ref{eq:blah}) to \eqref{eq:blah} (note the use of eq: in the label!)

   sed -e  "s/(\\\\ref{\(eq:[^}]*\)})/\\\\eqref{\1}/g" < FarjounShaeffer.tex > text.tex

Mass rename using sed

for f in * ; do n=`echo $f | sed "s/\(.?*\) 1.m4a/\1.m4a/" `; mv  "$f" "$n"; done;
