1 #!/usr/bin/perl -w
2 #
3 # sms.alert - send an alert via smstools available at
4 # http://www.isis.de/~s.frings/smstools/
5 #
6 # based on qpage.alert and mail.alert by Jim Trocki, trockij@transmeta.com
7 #
8 # usage:
9 # sms.alter [flags...] -g group -s system 385abxxxxxx|name[ 12345|name...]
10 #
11 # flags which are standard:
12 #
13 # -u this is upalert
14 # -g grp group
15 # -s sys system
16 # -l time time to next alert
17 #
18 # flags specific to sms.alert: (all optional)
19 #
20 # -f send flash sms (directly to screen)
21 # -x send extended message (all output, smstools with split it in
22 # multiple smses if needed)
23 # -i hh:mm-hh:mm send sms only if it falls in this interval
24 #
25 # it users file /usr/local/etc/sms.addressbook as addressbook in format
26 #
27 # 123456 name
28 #
29 # where 123456 is phone number (with country prefix, but without +) and
30 # name is alias used like:
31 #
32 # sms.alert -f dobrica
33 #
34 # in mon.cf
