Save the output of a command using logsave

If you want to save the output of a certain command, and furthermore do it at preset time intervals, use logsave:

logsave foo /bin/ls

anaconda-ks.cfg
apache
foo
install.log
install.log.
syslog

and after that do a

more foo

Logsave is useful also because it prints the exact date and time of the event, before and after the command takes place.
