Without going into detailed analysis nor a deep understanding of what you are doing, twothree comments:
- the slashX functions differ only in one summand so could be boiled down into a single one with a parameter passed.
- a pipe organ like echo | grep | sed | awk | uniq | wc could almost certainly be boiled down to a single awk call.
- if the leasecheck.pl script is already available, why not expand it to do all the tasks?
- or create an overall awk script for the same reason.

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
