Write Linux (RHE) shell script from the given pseudo code

[ohcnetwork]

I need to write a Linux (RHE) shell script from the given pseudo code as follows.

[If statement 1 - Check to see if 10 minutes or longer has passes since the server started/rebooted.]
	[If statement 2 - Check to see if string returned from "curl localhost --max-time 10" contains the string "curl: (28) Operation timed out with 0 out of -1 bytes received"]
		// Restart Apache
	[If statement 2 End]
	[If statement 3 - Check to see if memory used is over xxx MB (because it appears that, when memory used is over xxx MB, Apache/Tomcat/Entire Server locks up/hangs)]
		// Restart server (not just Apache, but the entire server)
	[If statement 3 End]
[If statement 1 End]

Q. How do I write this (using Linux shell script)?

I'd appreciate any help. If you cannot help writing some specific part of the pseudo code, please help me on parts that you can help me ...
