wslip=$(hostname -I | awk '{print $1}')
port=10809PROXY_HTTP="http://${hostip}:${port}"set_proxy(){export http_proxy="${PROXY_HTTP}"export HTTP_PROXY="${PROXY_HTTP}"export https_proxy="${PROXY_HTTP}"export HTTPS_proxy="${PROXY_HTTP}"
}unset_proxy(){unset http_proxyunset HTTP_PROXYunset https_proxyunset HTTPS_PROXY
}test_setting(){echo "Host ip:" ${hostip}echo "WSL ip:" ${wslip}echo "Current proxy:" $https_proxy
}if [ "$1" = "set" ]
thenset_proxyelif [ "$1" = "unset" ]
thenunset_proxyelif [ "$1" = "test" ]
thentest_setting
elseecho "Unsupported arguments."
fi
