[Clug-tech] Bash Scripting

Hi all.

I'm writing a bash script to automate some tasks.  One of the tasks is
to add a block of text to a file.  The catch is that I only want this
block of text added if it is not already there (otherwise there'd be
multiple entries...)

I know I can use grep to find the text in question, but I'm not sure how
to use this in a bash script to equate to "this text exists".

So, in pseudo code, I'm after this:

targettext="some value"
if ($targettext not in $MYFILE)
	echo $targettext >> $MYFILE

How would I do this in bash?

Thanks for any tips.

Shawn
