    [SOLVED] Extracting used memory as a percentage from free -m

    This is just some code to get used memory as a percentage:

    Code:
    free -m | awk ' $1 == "Mem:" { print "(("$3 "/" $2 ")" "*100)"}' | bc -l | cut -d '.' -f -1
    Can it be simplified?

    Here's a version that does all the dirty work in awk:
    Code:
    free -m | awk '$1 == "Mem:" { printf "%.0f\n", (($3 / $2 ) *100)}'
