In my shell script, how to get the localhost's IPs (eth0 and
eth1) correctly? I know I can run 'ifconfig' and grep etc,
but it's maybe not that graceful.

Here is what I do, now idea if it's a good idea but maybe it
can help:

#! /bin/zsh
#
# this file:
#   https://dataswamp.org/~incal/conf/.zsh/ip

public-ip () {
    local name=$funcstack[1]
    local url='http://checkip.amazonaws.com'
    local open_dns=opendns.com
    echo $(curl --no-progress-meter $url) "($name)"
    dig +short myip.${open_dns} @resolver1.${open_dns}
}

inet () {
    local name=$funcstack[1]
    echo $(hostname -I | awk '{print $1}') "($name)"
    ifconfig $net | awk '/mask/{print $2}'
    ip addr show $net | awk '/inet /{print $2}' | cut -d '/' -f 1
}

list-ip () {
    public-ip
    inet
}
alias lip=list-ip

# $ lip
# 92.34.142.23
# 92.34.142.23
# 192.168.10.224
# 192.168.10.224
