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
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 !

replace(1) MySQL database replace(1)
NAME
replace - A utility program that is used by msql2mysql, but that has more general applicability as well. replace changes strings in place
in files or on the standard input. Uses a finite state machine to match longer strings first. Can be used to swap strings.
USAGE
replace [-?svIV] from to from to ... -- [files]
or
replace [-?svIV] from to from to ... < fromfile > tofile
SYNOPSIS
replace [-?|-I] [-s] [-v]
DESCRIPTION
replace
-?|-I info
-s silent
-v verbose
EXTRA INFO
Special characters in from string:
^ Match start of line.
$ Match end of line.
Match space-character, start of line or end of line. For a end the next replace starts locking at the end space-character. A
alone in a string matches only a space-character.
EXAMPLE
this command swaps a and b in the given files:
shell> replace a b b a -- file1 file2 ...
