bash scripting cannot executed in crontab
hi guys,
i have a problem.

a week ago i made a successful crontab that execute bash scripting daily, it worked well

but now, it doesn't work at all, in the mail i have:
"
/home/jimmy/cha/scripts/cekpderr

produced the following output:

lagi jalan
/home/jimmy/cha/scripts/cekpderr: isql: command not found
nawk: can't open file /home/jimmy/cha/db/cekpderr.db
source line number 1
isi variabel var adalah
/home/jimmy/cha/scripts/cekpderr: [: =: unary operator expected
cat: cannot open /home/jimmy/cha/db/cekpderr.db
"

i wonder why suddenly the crontab cannot execute the isql command.

and...
when i execute the script manually, not with crontab, it works well and produce the expected result

i have also tried to run the crontab using another user in the same group.

please help guys...

thanks before

Users who desire to have their .profile executed must explicitly do so in the crontab entry. Why?

The .profile file should be read when the user logs in. So, there should be no need to execute .profile file again in a cron job (since the cron job is run after the user logs in). Doesn't the cron require login from the user. Then, from where does the cron execute? Please help!! (1 Reply)

kep_reload

KEP_RELOAD(1)						      General Commands Manual						     KEP_RELOAD(1)

NAME

       kep_reload - Update Predict's Keplerian elements

SYNOPSIS

	kep_reload

DESCRIPTION

       KEP_RELOAD is a simple utility that forces an immediate reload of PREDICT's Keplerian database through a socket connection while PREDICT is
       running in server mode.	It is especially useful in environments where PREDICT runs continuously, and periodic  Keplerian  element  updates
       are made outside of PREDICT, such as through scripts run through a crontab.

       The  "kepupdate"  script  found	in this directory is an example of a Keplerian element update script that can be run on an automated basis
       through a crontab.  It is designed to be placed in your home directory under a subdirectory  called  "cronjobs".   It  downloads  Keplerian
       orbital	data  from  www.celestrak.com  using  the  HTTP  protocol.   (The  "wget" utility, available from the Free Software Foundation, is
       required, and is included in many Linux distrubutions.)

       Type crontab -e to edit your crontab.  Simply add the following entry:

	       0 8 * * * kepupdate

       and your orbital database will update each morning at 8:00 AM (provided you have a network connection at that time).

       See the crontab man page for more information on editing your crontab.
