用到的tmux

终端复用软件,跟screen一样,但是要强大的多。

1. 典型应用场景

自己电脑是客户端,平常ssh到linux服务器上编译运行调试软件,网络断开或者自己电脑挂掉之后,不想服务器上运行的程序也挂掉,这时候就可以用tmux了。还有就是tmux能方便的多开好几个窗口。tmux的作用是代理终端,以前你直接通过ssh通道来操作服务器的终端,现在通过ssh通道启动了1个tmux程序,由tmux程序代替你控制多个终端,这样你就拥有了一组终端,所以是个服务器开发神器。这个神器差不多长这样:

2. 配置

跟vim差不多,也是要在服务器本用户主目录下边放一个配置文件.tmux.conf,直接用这个吧,有些东西自己想调整可以看着改:

3. 几个概念

  1. session,会话
  2. window,窗口
  3. panel,面板

关系是“1个会话会包含几个窗口,1个窗口会包含几个面板”
当然,1个ssh通道可以启动好几个会话,每个会话都可以detach和attach,从而一下子恢复一组工作空间。网络断开之后也会恢复哦,不过服务器重启就没办法了,毕竟tmux是跑在服务器上的软件。

4. 常用命令

4.1 在tmux之外的命令

# 新建1个名叫hello的session
tmux new -s hello

# 列出当前有几个session
tmux ls

# 挂接到名叫hello的session,恢复先前的工作空间
tmux at -t hello

4.2 进入tmux后的命令。一般来说在tmux内部的常用命令都是组合键,先按下前缀键,再按下后边跟着的那个键。默认的前缀键是ctrl+b,上边的配置修改成了ctrl+a,因为a距离更近啊:)

# 退出当前panel;如果当前panel是该window的最后一个,就退出该window;如果该window是该session的最后1个,就退出该session。这个不带前缀键。
ctrl+d

# 安全退出当前session(detach),这样你以后还能重新挂接(attach)上来恢复工作空间。
ctrl+a, d

# 浏览并切换session
ctrl+a, s

# 浏览当前配置使用的快捷键列表,按q退出
ctrl+a, ?

# 新建一个window
ctrl+a, c

# 在前后两个window之间跳转
ctrl+a, ctrl+l

# 跳转到相应编号的window
ctrl+a, 1/2/3...

# 修改当前window的名称,默认都是个'bash'。是个逗号哈。
ctrl+a, ,

# 新建垂直切分的panel
ctrl+a, %

# 新建水平切分的panel
ctrl+a, "

# 在panel之间切换啊,跟vim的方向一样,不过都需要加个前缀
# 向左
ctrl+a, h
# 向右
ctrl+a, l
# 向下
ctrl+a, j
# 向上
ctrl+a, k

# 暂时将当前panel占据整个window,再按一次就切换回去,在复制的时候很有用。
ctrl+a, z

# 浏览历史,进入后就可以按vim的进行操作了,常用的是j,k, ctrl+b(向上翻页),ctrl+f(向下翻页)
ctrl+a, [

# 强制关闭当前panel
ctrl+a, x

# 强制关闭当前window
ctrl+a, &

# 切换panel布局,比如横向分屏变竖向
ctrl+a, space

# 旋转panel布局,比如左1右2,变为左2右1
ctrl+a, ctlr+o

# 微调panel大小,这个试一下就知道了
ctrl+a, ctrl+方向键

好了,常用的就是这些了。

有些终端颜色不一致,需要配置

~/.tmux.conf中添加

1
set -g default-terminal "screen-256color"

~/.bashrc中添加

1
alias tmux='tmux -2'
