I always consider the term “shell scripting” to be differed based on personal-state.
I found myself becoming a huge fan of awk… My shell functions tend to put heavy operations in awk…
I tend to put heavy work on utils like sed, awk, even python, not in shell itself.

This is a POSIX Shell funciton that lists HBAs in an AIX system.

lshba () { lsdev -F "name status physloc" | /usr/bin/env awk 'BEGIN {
    # Header
    print "name\tstatus\t\tphyslot\t\t\t\tWWPN\t\t\tPart #\tCCIN\tColoned WWPN";
}
 
$1 ~ /^fcs.+/ {
    # Name, Status, Physlot
    printf "%s\t%s\t%s\t",$1,$2,$3;
    cmd = "lscfg -vl "$1;
    while ((cmd | getline) > 0){
        FS=".";
        if (NF==18||NF==6){
            # Part Number, CCIN
            s = s"\t"$NF;
        }
        if (NF==14){
            # WWPN
            printf "%s", $NF;
            # Colonfy
            for (i=1; i<16; i=i+2){
                str = sprintf("%s:%s", str, substr($NF, i, 2))
            };
            printf("%s\t%s\n", s, substr(str, 2));
            s=str=""
        }
    }
    close(cmd);
    FS=" ";
}
'; }

This features awk's robust filtering, C-like operators, pipeline… This is NAWK variant in AIX. Old but still quite useful. Just a showcase of how elegence awk can be…And handy syntax highlighting of dokuwiki!
