i am having trouble getting this tool chain to send daily updates.
this is what i want it to do:have server storing security logs and need to contact admin via email in specific risk scenarios(loss of power,hacker attack,virus download,improper login, denied websites) but it also needs to send daily updates. this is what i have but it is not sending daily updates

$ cat my_check.sh
egrep -i 'warn|error' /var/log/messages | mail -s 'issues worth reviewing' some_user@some_host
$ ./my_check.sh
$ crontab -e
#
1 0 * * * /path/to/my_check.sh

any suggestions will be appreciated

I'd go step by step.

Step 1:
does it work direct from the cmd line ie
If that doesn't work, wrapping it in a script and cron isn't going to help.

If the direct cli call doesn't work, do you see any msgs?
Check the logfiles eg /var/log/messages, /var/log/maillog.
Also, try mailq -Ac, mailq -Lq http://www.oreillynet.com/linux/cmd/...p?path=m/mailq

Tell us what distro & version
Which MTA ? eg sendmail, postfix... ? Have a look in /etc.

thank you

egrep -i 'warn|error' /var/log/messages | mail -s 'issues worth reviewing' some_user@some_host

this worked sheesh knew it was something simple

So what was the fix: that looks exactly as your original post?
