crontab and a bash script

seefor · 01-27-2009, 10:23 AM

I've add the following via crontab -e:

Quote:

15 9 * * * /hunter/ngc/start.sh

here is the shell script:

Quote:

#!/bin/bash
/hunter/ngc/./gather.sh
/hunter/ngc/./trans_csv.sh
/hunter/ngc/./db_reload.sh

Here is the output from /var/log/cron:

Quote:

Jan 27 09:15:00 crbc-tacacs-1 CROND[9083]: (root) CMD (/mcasthunter/ngc/start.sh)

The script does not run even thought it states it does.
start.sh runs fine from a command line

Not sure what else to try

Thanks in advance.

Are all the scripts made executables? Try to look at the mail of the crontab owner (root), since any standard output or any standard error coming from a cron job (and not explicitly redirected to a file) is sent there. You may find some useful hint about what's coming up.

/hunter/ngc/start.sh: line 2: ./gather.sh: No such file or directory
/hunter/ngc/start.sh: line 3: ./trans_csv.sh: No such file or directory
/hunter/ngc/start.sh: line 4: ./db_reload.sh: No such file or directory

I just change it to:

Quote:

#!/bin/bash
/hunter/ngc/./gather.sh
/hunter/ngc/./trans_csv.sh
/hunter/ngc/./db_reload.sh

This morning!

Today so hopefully tomorrow it will run

Thanks for you help, with checking mail idea.
How do I make it out to a file in crontab, so it would be easier to look for it?

Thanks,
Sif

/hunter/ngc/./gather.sh

just change it to

Code:

/hunter/ngc/gather.sh

You need to give the full path.
or first cd to the directory

Code:

cd /hunter/ngc
./gather.sh

Why don't you run the script manually?
put it in your root directory and run it

Thanks, I will cd to the directory and give that a try.

We make changes to the all the devices in our network druing 2300 to 0700. I need it to gather all the data every morning at 9:15 AM, then a php script compares the past two days and generate a report to management morning of all the changes.

Thanks again

Code:

/hunter/ngc/./gather.sh

just remove the ./

Code:

/hunter/ngc/gather.sh

./ is to execute when you are in the directory, and it is not in the path.
So just give the whole path to the command

If you do not them sent by mail, just redirect both standard output and standard error to a file, directly from the crontab entry:

Code:

15 9 * * * /hunter/ngc/start.sh >> $HOME/cron.log 2>&1

The double redirection >> will append the output to the log file progressively.
