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

# usage: ./insert.sh mainfile insertedfile >outputfile
cat "$1" |
while read line
do
echo "$line"
if [[ "$line" == 'version "2.10"' ]]
then
cat "$2"
fi
done
this is my dirty solution
# usage: ./insert.sh mainfile insertedfile >outputfile
sed 's/\\/\\\\/g' "$1" | while read line
do
echo "$line"
if [[ "$line" == '\version "2.10"' ]]
then
cat "$2"
fi
done
Glad you've found a solution already. This stuff interests me so I
fiddled around until I got it to do what I thought you were trying to
do. Are you trying to append text to the first argument if it's version
2.10? If so then here's how I did it, although it can only append at
the end of the file, it can't stick it somewhere in the middle.
#!/bin/bash
# usage: ./insert.sh mainfile insertedfile outputfile
# read contents of first argument and look for 2.10, then
# check return status
version=$(cat "$1" | grep "2.10" ; echo $?)
# define full text of first arg
text=$(cat "$1")
# define source of text to be inserted
newtext=$(cat "$2")
# if return status is 0, then it found 2.10 in the file
# and will append text from arg 2 and redirect to
# filename given as arg 3
if [ "$version" == "0" ] ; then
echo "$text" "$newtext" > "$3"
else
echo "version is already 2.11"
fi
[END]
Even if this wasn't what you were looking for I had fun doing it :).
Best,
Jon
