This works with all strings as if one ends with a comma excluding the last
Code:
awk 'RT {T = T (T?RS:"(") $1; printf "| " T ") " $1 FS; next} {print "| "$1}' RS=, file

Nice use of RT, however RT is GNU awk only.

Here is another option using RS=, which should work with any POSIX awk:
Code:
awk 'p{printf "| (%s) %s ",s p,p; s=s p RS } {p=$1} END{print "| " p}' RS=, file

Of course, these options only work with single lines, otherwise we would need to add NR%c conditions

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
