[SOLVED] Memory Usage more human reader

Nili · 2020-08-28 13:13:26

Hello! Anyone can change this script from MB to GB. I use it to display memory "used/total (%percentages)"

It display something like:
423/1979MB (21%)

But wish it display
423/1.9Gi (21%) or 423/2G (21%)
I was looking on the Internet, although I found some possibilities i could not achieved the goal.

So this is the command, anyone can fix it please?

free -m | awk 'NR==2{printf "%s/%sMB (%u%%)\n", $3,$2,$3*100/$2 }'

Thank you!

Edit:

free -h | awk '/Mem\:/ { print $2 }'

This is good add, but i find it difficult to attach on the above code.

free -h | awk 'NR==2{printf "%s/%s",$3,$2}'; free -m |awk 'NR==2{printf "  (%u%%)\n",$3*100/$2 }'

since it adds Units to each field according to size and math does not need them.

Very accurate JCN-9000! Exactly such i wanted. Thank you very much bro!

NICE!!!!

Another request, sorry, but seems that it can be done.

Can we remove those "i" from "Mi / Gi" to "M" or "G" so

370Mi/1.9Gi (18%)
to be
370M/1.9G (18%)

^Such would be a totally human reader.

a slight change to JCN-9000's line will do it:

free -h --si | awk 'NR==2{printf "%s/%s",$3,$2}'; free -h |awk 'NR==2{printf "  (%u%%)\n",$3*100/$2 }'

 28 Aug 20 @ 12:49:39 ~
   $ free -h --si | awk 'NR==2{printf "%s/%s",$3,$2}'; free -h |awk 'NR==2{printf "  (%u%%)\n",$3*100/$2 }'
1.1G/14G  (8%)

damo · 2020-08-28 15:50:49

F=$(free -h | awk 'NR==2{printf "%s/%s",$3,$2}'; free -m |awk 'NR==2{printf "  (%u%%)\n",$3*100/$2 }')

echo ${F//i}

1.0G/31G (3%)

Thanks S11
This is the best solution

free -h --si | awk 'NR==2{printf "%s/%s",$3,$2}'; free -m | awk 'NR==2{printf" (%u%%)\n",$3*100/$2 }'

I only changed from your code "free -h" to "free -m" because free -h gave me
358M/2.0G (18842%)

Now i have ideally completed results.
MM: » 391M/2.0G (19%)

Thanks guys, you fixed to the best possible

Interesting!

All three of these work for me:

 28 Aug 20 @ 14:32:38 ~
   $ free -h --si | awk 'NR==2{printf "%s/%s",$3,$2}'; free -h |awk 'NR==2{printf "  (%u%%)\n",$3*100/$2 }'
1.0G/14G  (7%)
 
 28 Aug 20 @ 14:33:11 ~
   $ free -h --si | awk 'NR==2{printf "%s/%s",$3,$2}'; free -m |awk 'NR==2{printf "  (%u%%)\n",$3*100/$2 }'
1.0G/14G  (7%)
 
 28 Aug 20 @ 14:33:19 ~
   $ free -h --si | awk 'NR==2{printf "%s/%s",$3,$2}'; free |awk 'NR==2{printf "  (%u%%)\n",$3*100/$2 }'
1.0G/14G  (7%)
 
 28 Aug 20 @ 14:33:35 ~
   $

BUT what's important - what works for you.

Nili · 2020-08-28 17:56:28

free -h calculate percentages on byte range to me. Like the one
1 (36421%)
2 ok (35%)
3 ok (35%)
So yeah, whatever it works

Sector11 · 2020-08-28 19:03:19

I know it's not what you wanted but look at these:

 28 Aug 20 @ 16:03:47 ~
   $ free --gibi | awk 'NR==2{printf "%s/%s",$3,$2}'; free |awk 'NR==2{printf "  (%u%%)\n",$3*100/$2 }'
1/13  (7%)
 
 28 Aug 20 @ 16:04:09 ~
   $ free --giga | awk 'NR==2{printf "%s/%s",$3,$2}'; free |awk 'NR==2{printf "  (%u%%)\n",$3*100/$2 }'
1/14  (7%)
 
 28 Aug 20 @ 16:04:15 ~
   $ free --mebi | awk 'NR==2{printf "%s/%s",$3,$2}'; free |awk 'NR==2{printf "  (%u%%)\n",$3*100/$2 }'
1071/14019  (7%)
 
 28 Aug 20 @ 16:04:33 ~
   $ free --mega | awk 'NR==2{printf "%s/%s",$3,$2}'; free |awk 'NR==2{printf "  (%u%%)\n",$3*100/$2 }'
1123/14700  (7%)

Woah! how many choices, S11 you're incredible. I'll save two or three of those.
I'm already overwhelmed

Sector11 · 2020-08-28 20:30:46

Noooooo not me, thank JCN-9000 he deserves the credit.

I'm just playing with his line of code that I would never even guessed at and the "free" manpage.

Nili · 2020-08-28 20:58:59

Both of you who offers your help are sincerely thanked. I have very good output memory usages now.

Certainly! @admin, @mod @members and their help is the greatest value a distro has. Even if one is forgotten without being mentioned, it is not done intentionally. A part of his help or codes that lives in any system is always remembered in a way by the end-user.
