How to use

0.3 config file

lookbusy 0.3.0
You are busy.

USAGE:
    lookbusy [OPTIONS]

OPTIONS:
    -c, --cpu-num <CPU_NUM>      how many cpu thread you want use [env: CPU_NUM=] [default: 1]
    -C, --config <CONFIG>        precise control cpu core by config file -C config.toml [env:
                                 CONFIG=]
    -h, --help                   Print help information
    -l, --limit <LIMIT>          cpu usage per thread % [env: LIMIT=] [default: 1]
    -L, --log-path <LOG_PATH>    fake log print [env: LOG_PATH=]
    -m, --mem-size <MEM_SIZE>    how many MB you want use [env: MEM_SIZE=] [default: 1024]
    -V, --version                Print version information

you can use command to quick start

./lookbusy -c 2 -m 4096

or use config file to control cpu core usage precisely

./lookbusy -C config.toml

toml example see config.example.toml

0.2

USAGE:
    lookbusy [OPTIONS]

OPTIONS:
    -c, --cpu-num <CPU_NUM>      how many cpu thread you want use [default: 1]
    -C, --config <CONFIG>        precise control cpu core usage 0/1,3/1,5/1 core0,3,5 use 100% cpu
    -h, --help                   Print help information
    -l, --limit <LIMIT>          cpu usage per thread % [default: 1]
    -L, --log-path <LOG_PATH>    fake log print
    -m, --mem-size <MEM_SIZE>    how many MB you want use [default: 1024]
    -V, --version                Print version information

Config details

[Core index] / [Cpu Usage Limit] / [Cpu Jitter]

Example:

0/0.5/0.5,4/1
core 0, Cpu 50% and with 50% jitter, so 0%-50% in core0.
core 4, Cpu 100%, 100% in core4.

Just like ./lookbusy -c 2 -m 4096
