From the crontab(5) man page:
Step values can be used in conjunction with ranges. Following a range
with ``/<number>'' specifies skips of the number's value through the
range. For example, ``0-23/2'' can be used in the hours field to spec‐
ify command execution every other hour (the alternative in the V7 stan‐
dard is ``0,2,4,6,8,10,12,14,16,18,20,22''). Steps are also permitted
after an asterisk, so if you want to say ``every two hours'', just use
``*/2''.
I don't think */1 in the minute field is really what you want.
Keep in mind that running a script from the command line is *very* different
than running it through 'cron'. 'cron' has none of your user's environment
for one thing. So you should make sure that all file references have full
paths, for example.
None of this is Cygwin-specific. Since this list is dedicated to the
discussion of Cygwin issues, discussions outside that area are discouraged.
If you're not sure how 'cron' should work, I recommend checking out man pages
and other documentation available on-line for help over that hurdle. If in
the process you find something that's a Cygwin issue, that's something to
bring back up with this list.
