I have a directory with crash logs, and I'd like to use a conditional statement in a bash script based on a find command.

The log files are stored in this format:

 /var/log/crashes/app-2012-08-28.log
 /var/log/crashes/otherapp-2012-08-28.log

I want the if statement to only return true if there is a crash log for a specific app which has been modified in the last 5 minutes. The `find` command that I would use is:

 find /var/log/crashes -name app-\*\.log -mmin -5

I'm not sure how to incorporate that into an `if` statement properly. I think this might work:

	if [ test `find /var/log/crashes -name app-\*\.log -mmin -5` ] then
	 service myapp restart
	fi

There are a few areas where I'm unclear:

- I've looked at the [if flags](http://tldp.org/LDP/Bash-Beginners-Guide/html/sect_07_01.html) but I'm not sure which one, if any, that I should use.
- Do I need the `test` directive or should I just process against the results of the find command directly, or maybe use ` find... | wc -l` to get a line count instead?
- Not 100% necessary to answer this question, but `test` is for testing against return codes that commands return? And they are sort of invisible - outside of `stdout` / `stderr`? I read the `man` page but I'm still pretty unclear about when to use `test` and how to debug it.
