what's wrong with my awk line?

Code:

[[ `free |awk '/Mem/{print int($2/1024/1024)}'` -lt 2 ]] && { echo "The free mem need to be more than 2G" }

This should be sufficient:

Code:

free | awk '/Mem/ && int($2/1024/1024) < 2 {print "The free mem need to be more than 2G"}'

A semi-colon perhaps:

Code:

[[ `free |awk '/Mem/{print int($2/1024/1024)}'` -lt 2 ]] && { echo "The free mem need to be more than 2G"; }

Guru.

Code:

[[ `free |awk '/Mem/{print int($2/1024/1024)}'` -lt 2 ]] && echo "The free mem need to be more than 2G"

The braces are not at all needed. Braces are used to group commands to be run in the same shell and you have only 1 echo command.
