计算 $b 相对于 $a 的路径的算法
<?php
function rel($b, $a, $lvl = 1) {
$first_b = retrieve_first($b);
$first_a = retrieve_first($a);
if (!$first_a) {
return ltrim($b, '/');
}
if (!$first_b) {
return '../' . rel($b, rm_first($a), $lvl);

这个脚本是服务器上shadowsocks的服务器的守护进程，脚本放在config.json相同的目录中，然后配置一个每分钟运行的crontab，该脚本会保证自己只有一个实例在运行，脚本的功能是每秒扫瞄一次，看ssserver进程是否还在运行中，如果找不到ssserver，就重新启动一个ssserver。
#!/bin/bash
base_path=$(cd `dirname $0`;pwd)
daemon_pid=$base_path/daemon.pid
if [ -e $daemon_pid ]; then
pid=`cat $daemon_pid`
exist=`ps aux | grep $pid | grep -v grep`
if [ ${#exist} -gt 0 ]; then
exit 0
else
echo -n '' > $daemon_pid
