NAME
pmap - report memory map of a process SYNOPSIS
pmap [options] pid [...] DESCRIPTION
The pmap command reports the memory map of a process or processes. OPTIONS
-x, --extended Show the extended format. -d, --device Show the device format. -q, --quiet Do not display some header or footer lines. -A, --range low,high Limit results to the given range to low and high address range. Notice that the low and high arguments are single string separated with comma. -X Show even more details than the -x option. WARNING: format changes according to /proc/PID/smaps -XX Show everything the kernel provides -p, --show-path Show full path to files in the mapping column -c, --read-rc Read the default configuration -C, --read-rc-from file Read the configuration from file -n, --create-rc Create new default configuration -N, --create-rc-to file Create new configuration to file -h, --help Display help text and exit. -V, --version Display version information and exit. EXIT STATUS
0 Success. 1 Failure. 42 Did not find all processes asked for. SEE ALSO

NAME
free - Display amount of free and used memory in the system SYNOPSIS
free [options] DESCRIPTION
free displays the total amount of free and used physical and swap memory in the system, as well as the buffers and caches used by the ker- nel. The information is gathered by parsing /proc/meminfo. The displayed columns are: total Total installed memory (MemTotal and SwapTotal in /proc/meminfo) used Used memory (calculated as total - free) free Unused memory (MemFree and SwapFree in /proc/meminfo) shared Memory used (mostly) by tmpfs (Shmem in /proc/meminfo, available on kernels 2.6.32, displayed as zero if not available) buffers Memory used by kernel buffers (Buffers in /proc/meminfo) cached Memory used by the page cache (calculated as Cached - Shmem in /proc/meminfo - the Cached value is actually the sum of page cache and tmpfs memory) OPTIONS
-b, --bytes Display the amount of memory in bytes. -k, --kilo Display the amount of memory in kilobytes. This is the default. -m, --mega Display the amount of memory in megabytes. -g, --giga Display the amount of memory in gigabytes. --tera Display the amount of memory in terabytes. -h, --human Show all output fields automatically scaled to shortest three digit unit and display the units of print out. Following units are used. B = bytes K = kilos M = megas G = gigas T = teras If unit is missing, and you have petabyte of RAM or swap, the number is in terabytes and columns might not be aligned with header. -c, --count count Display the result count times. Requires the -s option. -l, --lohi Show detailed low and high memory statistics. -o, --old Display the output in old format, the only difference being this option will disable the display of the "buffer adjusted" line. -s, --seconds seconds Continuously display the result delay seconds apart. You may actually specify any floating point number for delay, usleep(3) is used for microsecond resolution delay times. --si Use power of 1000 not 1024. -t, --total Display a line showing the column totals. --help Print help. -V, --version Display version information.
