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

NAME
members - outputs members of a group SYNOPSIS
members groupname DESCRIPTION
This manual page documents briefly the members commands. This manual page was written for the Debian GNU/Linux distribution. members is a program that sends a space-separated list of secondary member names to its standard output. OPTIONS
The programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. -a, --all Show all group members on one line. This is the default. -p, --primary Show only primary group members. -s, --secondary Show only secondary group members. -t, --two-lines Send two lines to standard output. First line is primary members, second line is secondary members. NOTE: This always displays two lines, even if there are no members at all. -h, --help Show summary of options. DIAGNOSTICS
Exit status is 0 (i.e. "success") if the group was found, and 1 (i.e., "failure") if the group was not found. Technically, the exit status hinges on the output of getgrnam(3) as follows: if getgrnam(3) returns a null pointer, the exit status is 1, and 0 otherwise. BUGS
I don't know of any! If you find one, please let me know! SEE ALSO
