I hope i have understood you correctly: regular expressions can be made to apply only on a limited group of lines:
Code:
sed -n '/start/,/finish/ {
p
}
will start printing lines (the "p" command) on the line containing "start" and continue to print the lines until it finds a line containing "finish", when it will stop printing them, until it again encounters a line containing "start", etc.
To print only the last group of lines is a bit tricky: copy everything in one such group to the holdspace, overwriting it every time a new group starts. Upon reaching the last line output the hold space and you are done.
Code:
sed -n '/^Finished/ {
H
}
$ {
x
p
}
/^Started/,/^Finished/ {
/^Started/ {
h
}
/^Started/ !{
H
}
}'

GROUP.CONF(5) Linux-PAM Manual GROUP.CONF(5)NAME
group.conf - configuration file for the pam_group module
DESCRIPTION
The pam_group PAM module does not authenticate the user, but instead it grants group memberships (in the credential setting phase of the
authentication module) to the user. Such memberships are based on the service they are applying for.
For this module to function correctly there must be a correctly formatted /etc/security/group.conf file present. White spaces are ignored
and lines maybe extended with '' (escaped newlines). Text following a '#' is ignored to the end of the line.
The syntax of the lines is as follows:
services;ttys;users;times;groups
The first field, the services field, is a logic list of PAM service names that the rule applies to.
The second field, the tty field, is a logic list of terminal names that this rule applies to.
The third field, the users field, is a logic list of users, or a UNIX group, or a netgroup of users to whom this rule applies. Group names
are preceded by a '%' symbol, while netgroup names are preceded by a '@' symbol.
For these items the simple wildcard '*' may be used only once. With UNIX groups or netgroups no wildcards or logic operators are allowed.
The times field is used to indicate "when" these groups are to be given to the user. The format here is a logic list of day/time-range
entries. The days are specified by a sequence of two character entries, MoTuSa for example is Monday Tuesday and Saturday. Note that
repeated days are unset MoMo = no day, and MoWk = all weekdays bar Monday. The two character combinations accepted are Mo Tu We Th Fr Sa Su
Wk Wd Al, the last two being week-end days and all 7 days of the week respectively. As a final example, AlFr means all days except Friday.
Each day/time-range can be prefixed with a '!' to indicate "anything but". The time-range part is two 24-hour times HHMM, separated by a
hyphen, indicating the start and finish time (if the finish time is smaller than the start time it is deemed to apply on the following
day).
The groups field is a comma or space separated list of groups that the user inherits membership of. These groups are added if the previous
fields are satisfied by the user's request.
For a rule to be active, ALL of service+ttys+users must be satisfied by the applying process.
EXAMPLES
These are some example lines which might be specified in /etc/security/group.conf.
Running 'xsh' on tty* (any ttyXXX device), the user 'us' is given access to the floppy (through membership of the floppy group)
xsh;tty*&!ttyp*;us;Al0000-2400;floppy
Running 'xsh' on tty* (any ttyXXX device), the user 'sword' is given access to games (through membership of the floppy group) after work
hours.
xsh; tty* ;sword;!Wk0900-1800;games, sound
xsh; tty* ;*;Al0900-1800;floppy
Any member of the group 'admin' running 'xsh' on tty*, is granted access (at any time) to the group 'plugdev'
xsh; tty* ;%admin;Al0000-2400;plugdev
