If i understand you correctly, you have two different formats to deal with. perhaps:
Code:
$ cat old
members 1.1.1.1:https
members 1.1.1.2:https
members 1.1.1.3:https
$ ./scottzx7rr.sh old
3
$ ### Note that i emptied the Happy2 members section for testing purposes
$ cat new
pool Happy1 {
monitor all happy1-check
members
1.1.1.1:https
1.1.1.2:https
1.1.1.3:https
1.1.1.4:https
1.1.1.5:https
1.1.1.6:https
}
pool Happy2 {
members
}
pool Happy3 {
monitor all happy3-check
members
1.1.3.4:https
}
pool Happy4 {
members
1.1.4.4:https
}
pool Happy5 {
monitor all happy5-check
members
1.1.5.4:https
}
$ ./scottzx7rr.sh new
9
$ cat scottzx7rr.sh
#!/bin/sh
# Try the old format. if egrep finds nothing, then try the new
if ! egrep 'members ([0-9]+\.){3}[0-9]+' "$1"; then
sed -n '/members/,/}/{/members/d;/}/d;p;}' "$1"
fi | wc -l
The egrep doesn't do a strict job of matching an ip address, but you can tighten that up if the code is of any use to you and you think it's required

gpasswd
GPASSWD(1) General Commands Manual GPASSWD(1)NAME
gpasswd - administer the /etc/group file
SYNOPSIS
gpasswd group
gpasswd -a user group
gpasswd -d user group
gpasswd -R group
gpasswd -r group
gpasswd [-A user,...] [-M user,...] group
DESCRIPTION
gpasswd is used to administer the /etc/group file (and /etc/gshadow file if compiled with SHADOWGRP defined). Every group can have adminis-
trators, members and a password. System administrator can use -A option to define group administrator(s) and -M option to define members
and has all rights of group administrators and members.
Group administrator can add and delete users using -a and -d options respectively. Administrators can use -r option to remove group pass-
word. When no password is set only group members can use newgrp(1) to join the group. Option -R disables access to the group through new-
grp(1) command.
gpasswd called by a group administrator with group name only prompts for the group password. If password is set the members can still new-
grp(1) without a password, non-members must supply the password.
FILES
/etc/group - group information
/etc/gshadow - shadow group information
