Whats wrong with my script?
I am trying to find a value within a properties file and declare it into a variable. Script below. I want the "memSize" to be the branch from the properties file. Right now it always tells me "Not found" What am I doing wrong?

Code:
#!/bin/sh
memsize ='';
memSize=`sed '/^\#/d' LoaderMemorySettings.properties | grep '$256' ` ; 
echo $memSize

Contents of properties file:

Code:
768= LAX
256=ORD

It's kinda weird that your properties file looks like that, I think the key and value should be reversed...but it's ok, so the expected output is "ORD", right?
Try this:
Code:
memSize=`grep '^256' aaa | cut -d= -f 2`
echo $memSize

I would guess you still have a space in your declaration of memSize?

Code:
memSize =...

Variables should not have any spacing before or directly after the =

Thanks for respones. I changed it to below. I now get an output of blank line followed by "TEST". So my memSize variable apparently gets modified but never displays. Am I doing something still wrong here?
Code:
#!/bin/sh    
test="TEST";
memSize="TEST2";
memSize=`grep '^256' LoaderMemorySettings.properties | cut -d= -f 2`;
echo $memSize
echo $test

The code works for me.

One command would do, but the output should be the same:

Code:
$ sed -n "/^256/s/.*=//p" LoaderMemorySettings.properties 
ORD

Code:
$ X=$($ sed -n "/^256/s/.*=//p" LoaderMemorySettings.properties)
$ echo $X
ORD

Assuming that your "LoaderMemorySettings.properties" file has a line exactly starting with 256=...

Sorry, "aaa" is the name of my test input file, you have to change it to your properties file:
