Command Line Options
You selection of statistics to put in the non-scrolled region and hidden is saved a config file. If you choose another config file on start up, you can have set of statistics per for each use case.
$ memfo -h
usage: memfo [-h] [-u {KiB,MB,MiB,GB,GiB,human}] [-c CONFIG]
[-i INTERVAL_SEC] [--vmalloc-total] [-z] [-d] [--DB]
options:
-h, --help show this help message and exit
-u {KiB,MB,MiB,GB,GiB,human}, --units {KiB,MB,MiB,GB,GiB,human}
units of memory [dflt=MiB]
-c CONFIG, --config CONFIG
use "{config}.ini" for configuration
-i INTERVAL_SEC, --interval-sec INTERVAL_SEC
loop interval in seconds [dflt=1.0]
--vmalloc-total Show "VmallocTotal" row (which is mostly useless)
-z, --zeros Show lines with all zeros
-d, --dump "print" the data only once rather than "display" it
