FREE(1) Linux User's Manual FREE(1) NAME
free - display information about free and used memory on the system SYNOPSIS
free [-b|-k|-m|-g] [-l] [-o] [-t] [-s delay ] [-c count ] DESCRIPTION
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. OPTIONS
Normal invocation of free(1) does not require any options. The output, however, can be fine-tuned by specifying one or more of the follow- ing 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 speci- fied, 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. --help Display usage information and exit FILES
