SYNOPSIS

smemstat [options] [delay [count]]

DESCRIPTION

smemstat reports the physical memory usage taking into consideration shared memory.

Swap reports memory that is swapped out to disk. Unshared memory is reported as USS (Unique Set Size). Unshared memory including the proportion of shared memory is reported as the PSS (Proportional Set Size). The non-swapped physical memory is reported as the RSS (Resident Set Size).

Running with root privilege will report all user space processes, otherwise running without will just report the current user's processes.

If a delay and count are not specified, a snapshot of the current memory used by the user's processes is report.

If a delay in seconds is specified, smemstat will periodically show any per-process changes in memory; the interval being the specified delay. This will run indefinitely until a SIGINT is caught. Specifying count will repeat the periodic output count number of times.
