Usage
$ scron -h Usage: scron <basedir>
<basedir> is the directory where the time-interval tree of "scrontab" files can be found (files whose extension is scm). The time-interval directory indicates the interval between two consecutive scron runs in seconds. So, for example, if the time-interval directory is 5, scron will run the scrontab files in that directory in 5 seconds intervals.
Example:
$ ls -l scron/
total 0
drwxr-xr-x 2 mario mario 48 Fev 13 09:11 5
$ ls -l scron/5/
total 4
-rw-r--r-- 1 mario mario 189 Fev 13 09:16 hello.scm
$ cat scron/5/hello.scm
(use posix)
(with-output-to-file (make-absolute-pathname "tmp" "hello.log")
(lambda ()
(print "Hello! It's "
(time->string (seconds->local-time (current-seconds)))))
append:)
$ scron scron &That'd generate a /tmp/hello.log file with a "Hello! It's <time>" line for each 5 seconds interval.
