"free command not found" while running bash script using git bash

Question

I want to display server load, disk space, usage and memory usage in bash script.

But when I try

echo "Memory usage:"
memory_usage=$ free -m | awk 'NR==2{printf "Memory Usage: %s/%sMB (%.2f%%)\n", $3,$2,$3*100/$2 }'
echo $memory_usage

this and run the script using ./test.sh it gives me the error:

free command not found

To store the output of a command, say var=$(command). Your var=$ command is wrong - note the space and the lack of parentheses around the command. — fedorqui

memory_usage=$(free -m | awk 'NR==2{printf "Memory Usage: %s/%sMB (%.2f%%)\n", $3,$2,$3*100/$2 }') this is also give same error. — Kim Jones

Well this clearly means that you don't have the free package installed. Check How to add more commands to Git Bash Shell. — fedorqui
