每个平台的信号定义或许有些不同。下面列出了POSIX中定义的信号。 Linux 使用34-64信号用作实时系统中。命令man 7 signal提供了官方的信号介绍。

在POSIX.1-1990标准中定义的信号列表

Set rz and sz on Mac

There are a mess of troubles in sending and receiving files from my macbook to dev server, since I had no permission to excute command scp on dev server. Here is a lightweight, quick, and convenience tools which related with ssh, called lrzsz. lrzsz is a unix communication package providing the XMODEM, YMODEM, ZMODEM file transefer protocol which usually has been already installed in most of servers.

Prerequisites

iTerm2 is necessary. [Here][] is the official website.

ssh

    -C  压缩数据传输
    -f  后台登录用户名密码
    -N  不执行shell[与 -g 合用]
    -g  允许打开的端口让远程主机访问        
    -L  本地端口转发
    -R  远程端口转发

-p ssh 端口
