hi guys, i have a long output and cant figure out a flexible way to show the meta members from a device. please help. some device have 2,4 or 8 meta members but for this example i have 4 meta members, what is a flexible way to pull them out from this output? need your inputs thanks.

delete dev 6AD5;

Have a go with this:

awk '
    /----/ { next; }
    /Meta Device Members/ {
        snarf = 1;
        split( $(NF-1), a, "(" );
        n = a[2]+0;
        next;
    }

    snarf == 1 && $1 == "Dev" { snarf = 2; next; }

    n > 0 && snarf > 1 {
        gsub( "-->", "" );
        n--;
        printf( "delete dev %s\n", $1 );
        next;
    }
' input-file

do you mean to do it like this?

DEV=$1

symdg show $DEV -sid 123 >> showdev.txt

awk '
    /----/ { next; }
    /Meta Device Members/ {
        snarf = 1;
        split( $(NF-1), a, "(" );
        n = a[2]+0;
        next;
    }

    snarf == 1 && $1 == "Dev" { snarf = 2; next; }

    n > 0 && snarf > 1 {
        gsub( "-->", "" );
        n--;
        printf( "delete dev %s\n", $1 );
        next;
    }
' showdev.txt

try something like this...

awk '/Meta Configuration/{a=1}
a==1 {if ($0 ~ /[0-9]/ && b > 2){gsub("-->","",$0);print "delete dev "$1";"}else if($0 ~ /-----/){b++}}
b==4{a=0}' file

 
$ nawk '/Meta Device Members/{gsub("[()]","",$4);a=8+$4;for(i=1;i<a;i++){getline;if(i>=8)print "delete dev ",$(NF-7)}}' input.txt
delete dev  6AD2
delete dev  6AD3
delete dev  6AD4
delete dev  6AD5
