Run script through cron with user environment variables
Hi everyone,
I wrote a script that is supposed to be run by cron on a daily basis. It works just fine if I run it manually, but due to a lack of environment variables (which are available during my user session but not when cron runs the script) it keeps failing to run successfully.
Here's the complete scenario:
The run_lines.sh script executes the lines.sh script 6 times, each one with different parameters, like this:

run_lines.sh:
Code:
#!/bin/bash
/home/me/lines.sh 04 email1@mydomain.com
/home/me/lines.sh 05 email2@mydomain.com
/home/me/lines.sh 06 email3@mydomain.com

(Only 3 lines are shown above)
And here's the crontab entry:
Code:
15 08 * * * /home/me/run_lines.sh

Now here's what I'm thinking. I created a list of the environment variables that are available to my user session with:
Code:
env > env_user.log

Then I'm thinking about doing this in one of the scripts mentioned above (run_lines.sh or lines.sh):
Code:
while read line; do
export $line
done < env_user.log

That way when the script is run through cron, all the environment variables of my user session will be exported and made available to cron.
I also tried
Code:
15 08 * * * me /home/me/run_lines.sh

but my implementation of cron does not seem to allow that.
I've done it before but I'm not quite sure it's the most efficient way to go.
Any hints or ideas will be more than welcome.
Thanks in advance.

CHECKSECURITY(8)					      System Manager's Manual						  CHECKSECURITY(8)

NAME

       checksecurity - Run a collection of simple system checks

SYNOPSIS

       checksecurity

DESCRIPTION

       The checksecurity command runs a small collection of simple system checks which are designed to catch a few common security issues.  check-
       security is run by cron in a daily basis.

CONFIGURATION

       The checksecurity.conf file defines several configuration variables: MAILTO, CHECK_DISKFREE, CHECK_PASSWD and CHECK_SETUID LOGDIR.  Each is
       described below.

       The  checksecurity program works with a collection of plugins which are located in /usr/share/checksecurity and are configured individually
       by their own configuration file.

       CHECK_PASSWD If this is set to TRUE then the check-passwd script will be invoked.  This script is designed to report upon  system  accounts
       which  have  no passwords.  CHECK_DISKFREE If this is set to TRUE then the check-diskfree script will be invoked and will allow an alert to
       be sent if there is any mounted partition is running short on disk space.  CHECK_SETUID If this is set to TRUE then the check-setuid script
       will be invoked, this will compare the setuid binaries upon the system to those that existed previously and show the differences.

FILES

       /etc/checksecurity.conf
	      checksecurity configuration file
