If you had said this at the time, we could've debugged it further.... We have multiple people here on these forums who can help you but for that we need details.
0. A part of the problem is definitely when *multiple* people write helpful messages, it can be confusing especially when a newbie (as a person who has some problem) doesn't know what is going wrong. Now if they try to follow the advice of more than one person, they can easily get confused and frustrated. Not sure what can be done about this....
1. The mail you *are* getting is from cron, *not* the mail command in your script. cron does so because there is no such program as root.
2. If the cronjob hangs, that means there is some problem with it. Looks like other people noticed a missing space between two quoted strings for this (which makes grep hang waiting for input?)
3. As always, when something doesn't work, what is needed is to *examine* what is going on, not change things. Trying a *different* suggested solution *will* get you confused.
4. By examine, I mean do a ps to see what is running. A series of ps will tell you if the program/script is stuck somewhere or progressing but just taking more time.
5. Always a good idea to test a cronjob script by running it manually *before* installing it.
6. When a suggested step doesn't work, it may be a good idea to post a response saying "here is what I tried and here is what happens". That gives people a clue as to what is going and a further step can be suggested.
