How-To Geek
Display available memory on Linux / Ubuntu
Run this command from a terminal window. This works on debian, ubuntu, and redhat. I’m sure it works on others but those are the only ones I have access to.
cat /proc/meminfo
You should see results similar to this:
MemTotal: 3615716 kB MemFree: 132528 kB MemShared: 0 kB Buffers: 50028 kB Cached: 1572772 kB SwapCached: 80716 kB Active: 580208 kB Inactive: 1142848 kB HighTotal: 2752384 kB HighFree: 8576 kB LowTotal: 863332 kB LowFree: 123952 kB SwapTotal: 2104504 kB SwapFree: 1064540 kB

thanks
or use command free
hmmm… when i’m trying the command : free -m
the result is different.
cat /proc/meminfo :
MemTotal: 4054364 kB
MemFree: 338924 kB
free -m :
total used free shared buffers cached
Mem: 3959 3491 468 0 8 787
can U explain about this?
I know this was a while ago, but in case somebody else uses this page for reference.
The command ‘free -m’ will display the memory in MB’s where the ‘free’ alone is in kb’s
awsum!
i am using ubuntu10.10 and have a fortran program requires i find the MemTotal, MemFree, MemSwap.
What call should i use to change INFO to something like MEMSYS, SYSMEM, etc?
PROGRAM MEMORY
INTEGER MemTotal,MemFree,MemSwap
CALL INFO(MemTotal)
CALL INFO(MemFee)
CALL INFO(MemSwap)
write(*,*) MemTotal
write(*,*) MemFree
write(*,*) MemSwap
END
