1、常用命令
screen -ls # 查看所有screen
screen -S # 创建screen，并命名
ctr + A, D # 快捷键，退出当前screen
screen -r # 进入screen
screen -X quit # 删除screen，但没有指定会话
screen -X -S [session you want to kill] quit #删除screen，指定会话
screen -wipe # 清除dead screens 2、快捷键
# 默认的 command key 是 ctrl+a
escape `` #指定command key 为 `，并指定在按下 ` 后再按 `，相当于之前 C-a a 的效果
C-a ? #列出当前可用快捷键及其对应的命令
C-a : #进入命令输入模式，之后可输入并执行screen中的命令，比如quit强制关闭当前screen，比如split分屏
C-a d #使当前session处于Detached状态
C-a :quit #关闭当前会话
C-a c #新建窗口
C-a K #强制关闭当前窗口
C-a \" #显示当前会话的窗口列表，用j、k上下移动光标选择窗口，或直接用0-9选择窗口
C-a \' #输入窗口序号或title，选择指定窗口
C-a 0-9 #选择指定窗口
C-a n #选择下一个窗口
C-a [space] #选择下一个窗口
C-a p #选择上一个窗口
C-a C-a #移动到上一次选择的窗口
C-a A #修改当前窗口的title
C-a [ #进入复制模式。
C-a ] #将buffer中的内容粘贴出来，退出复制模式。vim 中最好是在insert模式下。3、配置
# screen的配置：
cp /etc/screenrc ~/.screenrc
# 再在 ~/.screenrc 中追加配置：
caption always "%3n %t%? @%u%?%? [%h]%?%=%c" # 底部倒数第二行信息条，显示当前窗口信息
hardstatus alwaysignore
hardstatus alwayslastline '%{bW}%-w%{.wB}%n %t%{-}%+w %=%{.w}' # # 底部倒数第一行信息条，显示当前会话的所有窗口4、其它
# 有些服务器上会遇到如下报错 screen Cannot open your terminal '/dev/xxx/x'
# 解决方案，命令行运行：
script /dev/null示例配置：
#
# This is an example for the global screenrc file.
# You may want to install this file as /usr/local/etc/screenrc.
# Check config.h for the exact location.
#
# Flaws of termcap and standard settings are done here.
#
#startup_message off
#defflow on # will force screen to process ^S/^Q
deflogin on
#autodetach off
vbell on
vbell_msg " Wuff ---- Wuff!! "
# all termcap entries are now duplicated as terminfo entries.
# only difference should be the slightly modified syntax, and check for
# terminfo entries, that are already corected in the database.
#
# G0 we have a SEMI-GRAPHICS-CHARACTER-MODE
# WS this sequence resizes our window.
# cs this sequence changes the scrollregion
# hs@ we have no hardware statusline. screen will only believe that
# there is a hardware status line if hs,ts,fs,ds are all set.
# ts to statusline
# fs from statusline
# ds delete statusline
# al add one line
# AL add multiple lines
# dl delete one line
# DL delete multiple lines
# ic insert one char (space)
# IC insert multiple chars
# nx terminal uses xon/xoff
