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)

cron(8) System Manager's Manual cron(8)NAME
cron - The system clock daemon
SYNOPSIS
/usr/sbin/cron
DESCRIPTION
The cron daemon runs shell commands at specified dates and times. Commands that are to run according to a regular or periodic schedule are
found within the crontab files. Commands that are to run once only are found within the at files. You submit crontab and at file entries
by using the crontab and at commands. Because the cron process exits only when killed or when the system stops, only one cron daemon
should exist on the system at any given time. Normally, you start the cron daemon from within a run command file.
During process initialization and when cron detects a change, it examines the crontab and at files. This strategy reduces the overhead of
checking for new or changed files at regularly scheduled intervals. The cron command creates a log of its activities. The cron daemon
must be started from the system startup scripts because it must begin execution without a login user ID set. The cron daemon starts each
job with the following process attributes stored with the job by the invoking process: Login user ID Effective and real user IDs Effective
and real group IDs Supplementary groups
It also establishes the following attributes from the authentication profile of the account associated with the login user ID of the invok-
ing process: Audit control and disposition masks Kernel authorizations
DIAGNOSTICS
The at and batch programs will refuse to accept jobs submitted from processes whose login user ID is different from the real user ID.
FILES
Specifies the command path. Main cron directory Directory containing the crontab files. List of allowed users. List of denied users His-
tory information for cron Queue description file for at, batch, and cron
