do you mean to do it like this?

Code:
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

its giving out

awk: syntax error near line 13
awk: illegal statement near line 13

ip-token

IP-TOKEN(8)							       Linux							       IP-TOKEN(8)

NAME

       ip-token - tokenized interface identifier support

SYNOPSIS

       ip token { COMMAND | help }

       ip token set TOKEN dev DEV

       ip token del dev DEV

       ip token get [ dev DEV ]

       ip token [ list ]

DESCRIPTION

       IPv6 tokenized interface identifier support is used for assigning well-known host-part addresses to nodes whilst still obtaining a global
       network prefix from Router advertisements. The primary target for tokenized identifiers are server platforms where addresses are usually
       manually configured, rather than using DHCPv6 or SLAAC. By using tokenized identifiers, hosts can still determine their network prefix by
       use of SLAAC, but more readily be automatically renumbered should their network prefix change [1]. Tokenized IPv6 Identifiers are described
       in the draft [1]: <draft-chown-6man-tokenised-ipv6-identifiers-02>.

   ip token set - set an interface token
       set the interface token to the kernel.

       TOKEN  the interface identifier token address.

       dev DEV
	      the networking interface.

   ip token del - delete an interface token
       delete the interface token from the kernel.

       dev DEV
	      the networking interface.

   ip token get - get the interface token from the kernel
       show a tokenized interface identifier of a particular networking device.  Arguments: coincide with the arguments of ip token set but the
       TOKEN must be left out.

   ip token list - list all interface tokens
       list all tokenized interface identifiers for the networking interfaces from the kernel.
