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?

No need for cat, grep, cut, and expr.

awk '/MemTotal/ {printf( "%.2f\n", $2 / 1024 )}' /proc/meminfo

Thanks a lot Scottn, Now its working

or you can try this:

vmstat -s -S M | egrep -ie 'memory|swap'
