有时候会有这样的问题,当在公司服务器上打开了一个终端,做了很多事情,或正开着某个服务程序,下班回家了。突然有事需要接入到服务器,如果用 ssh 连入,默认是一个新的终端,并不会打开你之前在公司的那个会话。而这时又需要继续在原来那个会话下操作。今天发现 linux 下有一个 screen 命令,很有用. 在开启终端后,先运行一下 screen ,这样后续的操作都会被绑定到这个 screen 上。 而且可以在其它ssh 会话上使用 screen 命令打开旧的会话 ,继续未完成的事,甚至可以多个ssh连入同时共享一个会话,输入的命令会在所有共享ssh客户端同时显示,非常有趣.例:A连上服务器,并运行 screen ssh user@serverscreen B连上服务器,打开A的会话ssh user@serverscreen -ls # 查看会话idscreen -rx xxxxx #打开指定的会话.更多请查看 screen 的帮助:Use: screen [-opts] [cmd [args]] or: screen -r [host.tty]Options:-a Force all capabilities into each window"s termcap.-A -[r|R] Adapt all windows to the new display width & height.-c file Read configuration file instead of ".screenrc".-d (-r) Detach the elsewhere running screen (and reattach here).-dmS name Start as daemon: Screen session in detached mode.-D (-r) Detach and logout remote (and reattach here).-D -RR Do whatever is needed to get a screen session.-e xy Change command characters.-f Flow control on, -fn = off, -fa = auto.-h lines Set the size of the scrollback history buffer.-i Interrupt output sooner when flow control is on.-l Login mode on (update /var/run/utmp), -ln = off.-list or -ls.
