利用rsync自动同步服务器与本地代码的python脚本

菜鸟表示写web时 每次修改完后把文件往VPS上丢很麻烦
用ssh sshfs scp都太慢 小东西又懒得用git
sublimetext上得sftp不支持中文 emacs干脆就只能ssh

于是用linux自带的rsync写了个同步脚本
可以手动或自动往服务器上差异性同步 不用scp一堆东西 也不用忍受ssh那个渣速度

把脚本copy到你的目录 修改脚本内的配置 如果在脚本内设置了密码 那每次上次就会自动输入密码 否则除非你设置本地key 否则都要输密码

如果代码在服务器上 先执行 ： python rsync.py -down 把代码download下来 ， 个人觉得先down下来再修改 不用忍受每次load一遍 比较舒服

每次修改完了 可以手动上传:python rsync,py 或者也可以放在后台自动上传：python rsync.py -auto 他会监视改目录的文件 如果新建 修改或删除 都会sync 可以用 nohup python rsync.py -auto& 来后台运行

只根据emacs优化了 vim党自己改

sync时会忽略隐藏文件和临时文件
