I have the following code which does the trick , but I was wondering if the code can be optimised in a single statement

Code:
awk -F '|' 'NR==FNR { a[$12]=$0; next  }a[$1] { print $0, a[$2] }' inst_full_denied mppartc.desc > test1
awk -F '|' 'NR==FNR { a[$13]=$0; next  }a[$1] { print $0, a[$2] }' inst_full_denied mppartc.desc >> test1
awk -F '|' 'NR==FNR { a[$14]=$0; next  }a[$1] { print $0, a[$2] }' inst_full_denied mppartc.desc >> test1
awk -F '|' 'NR==FNR { a[$15]=$0; next  }a[$1] { print $0, a[$2] }' inst_full_denied mppartc.desc >> test1
awk -F '|' 'NR==FNR { a[$16]=$0; next  }a[$1] { print $0, a[$2] }' inst_full_denied mppartc.desc >> test1
awk -F '|' 'NR==FNR { a[$17]=$0; next  }a[$1] { print $0, a[$2] }' inst_full_denied mppartc.desc >> test1
awk -F '|' 'NR==FNR { a[$18]=$0; next  }a[$1] { print $0, a[$2] }' inst_full_denied mppartc.desc >> test1
awk -F '|' 'NR==FNR { a[$19]=$0; next  }a[$1] { print $0, a[$2] }' inst_full_denied mppartc.desc >> test1
awk -F '|' 'NR==FNR { a[$20]=$0; next  }a[$1] { print $0, a[$2] }' inst_full_denied mppartc.desc >> test1

Any help will be appreciated!

merge

merge(1)																  merge(1)

NAME

       merge - three-way file merge

SYNOPSIS

       merge [-Llabel1 [-Llabel3]] [-p] [-q] file1 file2 file3

DESCRIPTION

       merge  incorporates  all  changes that lead from file2 to file3 into file1. The result goes to standard output if -p is present, into file1
       otherwise.  merge is useful for combining separate changes to an original.  Suppose file2 is the original, and both  file1  and	file3  are
       modifications of file2. Then merge combines both changes.

       An  overlap occurs if both file1 and file3 have changes in a common segment of lines. On a few older hosts where diff3 does not support the
       -E option, merge does not detect overlaps, and merely supplies the changed lines from file3.  On most hosts, if overlaps occur, merge  out-
       puts a message (unless the -q option is given), and includes both alternatives in the result.  The alternatives are delimited as follows:

       <<<<<<< file1 lines in file1 ======= lines in file3 >>>>>>> file3

       If  there  are  overlaps,  the  user  should edit the result and delete one of the alternatives. If the -L label1 and -L label3 options are
       given, the labels are output in place of the names file1 and file3 in overlap reports.

DIAGNOSTICS

       Exit status is 0 for no overlaps, 1 for some overlaps, 2 for trouble.
