manipulating .ly with bash - echo drops \

[Rob Canning]

hello,

i have generated a lilypond file and would like to be able to manipulate 
the file with bash scripts.

first thing i would like to do is insert some additional stuff one line 
under the 'version "2.10" line.

the script i have is below - the problem is the echo "$line" bit drops 
all the \ from  the score.

anyone know a way to fix this script so all the \ remain intact?

thanks

rob


# usage: ./insert.sh mainfile insertedfile >outputfile
cat "$1" |
while read line
do
echo "$line"
if [[ "$line" == 'version "2.10"' ]]
then
cat "$2"
fi
done
