Default Check Available Memory Linux
To check avilable memory in Linux type free -m command. free displays the total amount of free and used physical and swap memory in the system, as well as the buffers used by the kernel.
Code:
free -m
free -h
free -b
Output:
Code:
             total       used       free     shared    buffers     cached
Mem:          2025       1961         64          0        172       1035
-/+ buffers/cache:        753       1272
Swap:         1906          0       1906
  1. The -b switch displays the amount of memory in bytes
  2. The -k switch (set by default) displays it in kilobytes
  3. The -m switch displays it in megabytes
  4. The -g switch displays it in gigabytes.
Code:
vmstat
Output:
Code:
procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu----

  1. swpd: the amount of virtual memory used.
  2. free: the amount of idle memory.
  3. buff: the amount of memory used as buffers.
  4. cache: the amount of memory used as cache.
