markdown语法缩进

行首添加TAB符号，如下脚本

#!/bin/bash
sudo sysctl net.inet.ip.forwarding=1
sudo sysctl net.inet.ip.redirect=1
sudo sysctl net.inet6.ip6.forwarding=1
sudo sysctl net.inet6.ip6.redirect=1
sudo pfctl -d
sleep 1

sudo pfctl -F all -f /etc/pf.conf
sleep 1

echo "
nat on en4 from bridge100:network to any -> (en4)
rdr pass on bridge100 inet proto tcp to port {443,80} -> 127.0.0.1 port 8888" | sudo pfctl -evf -

export MITMPROXY_SSLKEYLOGFILE=~/Documents/master-secret.log
mitmproxy -T -p 8888

可以转换成如下样式

#!/bin/bash 
sudo sysctl net.inet.ip.forwarding=1
sudo sysctl net.inet.ip.redirect=1
sudo sysctl net.inet6.ip6.forwarding=1
sudo sysctl net.inet6.ip6.redirect=1
sudo pfctl -d
sleep 1

sudo pfctl -F all -f /etc/pf.conf
sleep 1

echo "
nat on en4 from bridge100:network to any -> (en4)
rdr pass on bridge100 inet proto tcp to port {443,80} -> 127.0.0.1 port 8888" | sudo pfctl -evf -

export MITMPROXY_SSLKEYLOGFILE=~/Documents/master-secret.log
mitmproxy -T -p 8888
