Network To get the memory in MB

Hi
I am trying to get the memory in the box using the belkow command. this is giving me the proper result in KB's. I would like to convert it into MB's.

cat /proc/meminfo | grep MemTotal | cut -d " " -f6
32962184

But when I execute the below command, its throwing the error.

expr ` \( cat /proc/meminfo | grep MemTotal | cut -d " " -f6 \) / 1024 `
-bash: (: command not found
cut: ): No such file or directory
cut: /: Is a directory
cut: 1024: No such file or directory
expr: missing operand
Try `expr --help' for more information.


Can somebody please suggest me how to do it?

NAME
bbox - prints out the bounding box of a rawppm or rawpbm image SYNOPSIS
bbox [ -l ] [ -r ] [ -h ] [ -V ] [ rawpbmfile ] DESCRIPTION
bbox reads a rawppm or rawpbm file and prints out the bounding box of the image (as postscript comment and in postscript points, i.e. 1/72dpi) as well as the high resolution bounding box. Input is read from standard input if no filename is specified. Example output: %%BoundingBox: 12 253 829 837 %%HiResBoundingBox: 12.500000 253.000000 828.500000 837.00000 bbox has only very limited memory requirements as it reads the input line by line and thus needs to store only one picture line in memory. OPTIONS
-h | --help Show summary of options. -V Show version of program. -r resolution of picture in dpi -l loose bounding box (integer bounding box is expanded by 1 point, hires bounding box is expanded by 0.5 points) SEE ALSO
