Hello there,
here is small shell script which I use to run from crontab and redirect
its output to sendmail to produce rather readable messages. Maybe it would
be useful for you too ;-)
Any suggestions are, surely, appreciated. I live under FreeBSD and in
particular wanna know if there is more portable way to increment a
variable under shell than 'expr'
Sincerely,
D.Marck [DM5020, DM268-RIPE, DM3-RIPN]
