Bash: using SED, trying to replace some characters except first or last line

Hi,
I require to replace 2 items:
1. replace start of all lines in a file with ' except the first line
2. replace end of all lines in a file with '||chr( except last line

I am able to do the entire file using
Code:
sed  -e s/^/\'/g -e s/$/\'\|\|chr\(/g "$file" > newfile.txt

but am not yet able to incorporate the EXCEPT conditions as stated above. I have searched through the forums, but couldn't arrive at the expected output

Thanks !

This should do it:

Code:
sed -e '2,$s/^/'\''/g' -e '$!s/$/'\''||chr(/g' "$file" > newfile.txt

Just for fun, assuming the file is not too big:
Code:
perl -0777pe"s/\n(?!\z)/'||chr(\n'/g" file
