free − display information about free and used memory on the system
free [−b|-k|-m|-g] [−l] [−o] [−t] [−s delay ] [−c count ]
free(1) displays the total amount of free and used physical memory and swap space in the system, as well as the buffers and cache consumed by the kernel.
Normal
invocation of free(1) does not require any options.
The output, however, can be fine-tuned by specifying one or
more of the following flags:
−b, −−bytes
Display output in bytes.
−k, −−kb
Display output in kilobytes (KB). This is the default.
−m, −−mb
Display output in megabytes (MB).
−g, −−gb
Display output in gigabytes (GB).
−l, −−lowhigh
Display detailed information about low vs. high memory usage.
−o, −−old
Use old format. Specifically, do not display -/+ buffers/cache.
−t, −−total
Display total summary for physical memory + swap space.
−c n, −−count=n
Display statistics n times, then exit. Used in conjunction with the -s flag. Default is to display only once, unless -s was specified, in which case default is to repeat until interrupted.
−s n, −−repeat=n
Repeat, pausing every n seconds in-between.
−V, −−version
Display version information and exit.
