I've got an *extremely* simple script I want to run every minute:
So, the script is called "status", it's executable, and in the correct path, etc. In a terminal window (I'm using Mac OS X), I can type status, and it will create onlinestatus.txt with the ping output in it. Everything seems to be working fine.
HOWEVER, when I put the command in my crontab as
* * * * * status
It doesn't work. Or, to be more precise, it creates an *empty* onlinestatus.txt file. I can use Cronnix (a GUI crontab editor) to force the command to run. When I do that, onlinestatus.txt *does* contain the ping output; it seems like it's only when cron runs it at the scheduled interval that the text file comes out empty.
I'm *thoroughly* confused. If it didn't work *at all*, I could deal with it, but this behavior doesn't seem to make any sense. Any suggestions?
I have a cron job set to run a script everyday. If I run the script out side of cron it runs correctly. If cron runs the script is produces a 0 byte file and it puts the output in the / directory. The script is set to put the output in a specific directory. Any help would be appreciated. (8 Replies)

crontab
CRONTAB(1) BSD General Commands Manual CRONTAB(1)NAME
crontab -- maintain crontab files for individual users (V3)
SYNOPSIS
crontab [-u user] file
crontab [-u user] { -l | -r | -e }
DESCRIPTION
The crontab utility is the program used to install, deinstall or list the tables used to drive the cron(8) daemon in Vixie Cron. Each user
can have their own crontab, and they are not intended to be edited directly.
(Darwin note: Although cron(8) and crontab(5) are officially supported under Darwin, their functionality has been absorbed into launchd(8),
which provides a more flexible way of automatically executing commands. See launchctl(1) for more information.)
If the /usr/lib/cron/cron.allow file exists, then you must be listed therein in order to be allowed to use this command. If the
/usr/lib/cron/cron.allow file does not exist but the /usr/lib/cron/cron.deny file does exist, then you must not be listed in the
/usr/lib/cron/cron.deny file in order to use this command. If neither of these files exists, then depending on site-dependent configuration
parameters, only the super user will be allowed to use this command, or all users will be able to use this command. The format of these
files is one username per line, with no leading or trailing whitespace. Lines of other formats will be ignored, and so can be used for com-
ments.
The first form of this command is used to install a new crontab from some named file or standard input if the pseudo-filename '-' is given.
The following options are available:
-u Specify the name of the user whose crontab is to be tweaked. If this option is not given, crontab examines ``your'' crontab, i.e.,
the crontab of the person executing the command. Note that su(1) can confuse crontab and that if you are running inside of su(1) you
should always use the -u option for safety's sake.
-l Display the current crontab on standard output.
-r Remove the current crontab.
-e Edit the current crontab using the editor specified by the VISUAL or EDITOR environment variables. The specified editor must edit
the file in place; any editor that unlinks the file and recreates it cannot be used. After you exit from the editor, the modified
crontab will be installed automatically.
FILES
/usr/lib/cron/cron.allow
/usr/lib/cron/cron.deny
DIAGNOSTICS
A fairly informative usage message appears if you run it with a bad command line.
SEE ALSO crontab(5), compat(5), cron(8), launchctl(1)STANDARDS
The crontab command conforms to IEEE Std 1003.2 (``POSIX.2''). The new command syntax differs from previous versions of Vixie Cron, as well
as from the classic SVR3 syntax.
