still I didn’t got the solution I am stuck at that if statement at beginning I know it requires one argument to exit but I am not able to do it

Hi Hritik,

We have given

Usage: ./ /proc/meminfo"

What are we expecting here?? we want you to make use of command line arguments,
The code you have written contain “/proc/meminfo”, can you think of a way to use it from command line?

Our TODO gives a hint

  1. Start the expression to populate the variable with “cat $1” which is the command line filename input. Check the Usage above.

So try to use “cat $1” in the code that you have written, instead of hard coding /proc/meminfo

(Also you need not worry about the if condition block, all you need to do is “Add the line to populate the variable “totalMemInKB” with the value of the Total memory in KB.” as given in TODOs")

(And please do not post any Screenshot that contains the code that you have written)

sorry for posting images and I got what you said ,
I used cat $1 and passed the arg required thanks it helped
