是不是有个什么命令能把本地 ssh 窗口命令 输送到远程 server 上执行? 我想本地的 Bitvise SSH Client 窗口输入一个命令 启动 server 上的 firefox?

[google456]

google 一个
ssh root@ip firefox
貌似不对 还是无法启动 还是Error: no display specified

当然直接在server端启动firefox是没有问题的

[clino]

ssh -X

[google456]

@clino ssh -X root@ip firefox ??
无效

[clino]

@google456 看起来是windows下的应该就不支持了

[lululau]

ssh remote 'open /Applications/Firefox.app'

这样？

[whoops]

是在想在x下下启动firefox吧
export DISPLAY=:0.0
firefox ¨www.v2ex.com¨

[ETiV]

确定有显示器的话就 DISPLAY=:1 后接命令。export 出来也可以。
我树霉派上用这个加 mplayer 看片儿的

LS的 0.0 是啥意思？

[whoops]

@ETiV
DISPLAY后面的变量含义是这样的
[host]:<display>[.screen]
0.0是第一个显示器的第一屏
我的ubuntu启动并登陆x后export查看是declare -x DISPLAY=":0"

[whoops]

man X
查看X的手册里面有详细说明
From the user's perspective, every X server has a display name of the
form:

hostname:displaynumber.screennumber

This information is used by the application to determine how it should
connect to the server and which screen it should use by default (on
displays with multiple monitors):
hostname
The hostname specifies the name of the machine to which the
display is physically connected. If the hostname is not given,
the most efficient way of communicating to a server on the same
machine will be used.

displaynumber
The phrase "display" is usually used to refer to a collection
of monitors that share a common set of input devices (keyboard,
mouse, tablet, etc.). Most workstations tend to only have one
display. Larger, multi-user systems, however, frequently have
several displays so that more than one person can be doing
graphics work at once. To avoid confusion, each display on a
machine is assigned a display number (beginning at 0) when the
X server for that display is started. The display number must
always be given in a display name.

screennumber
Some displays share their input devices among two or more moni‐
tors. These may be configured as a single logical screen,
which allows windows to move across screens, or as individual
screens, each with their own set of windows. If configured
such that each monitor has its own set of windows, each screen
is assigned a screen number (beginning at 0) when the X server
for that display is started. If the screen number is not
given, screen 0 will be used.

@whoops 感谢 你这个方法可以
不过关闭本地ssh窗口 远程的浏览器也关闭了 怎么能让远程浏览器一直运行呢?

[google456]

@lululau 不行 ssh: Could not resolve hostname remote: Name or service not known

如果用 ssh root@ip remote 'open /Applications/Firefox.app'
会说bash: remote: command not found

[whoops]

@google456
两种方法，
第一种是保持firefox在运行，你再执行firefox url的时候就会打开一个标签，退出ssh的时候也不会关闭。
第二种是用nohup命令，你可以这样写
nohup firefox v2ex.com&
注意最后的&，不要丢掉了，这样你关闭ssh后或者启动firefox的终端后，firefox不会退出的。

[google456]

@whoops 嗯 nohup我也想到了 也确实没问题.

第一种方法 没看明白
本来不就是firefox ¨www.google.com¨ 这样吗
远程打开了google.com 但是关闭ssh窗口 firefox就直接关闭了.

[whoops]

@google456 用第二个方法吧，我表述有问题，保持firefox运行，这里的firefox运行不是由ssh启动的，你可以放到开机启动脚本中，登陆x后自启动，当你用ssh执行firefox url 后，再关闭，这个firefox进程不会随着你的ssh退出而退出的，忘了它吧，有点繁琐.

用screen目测也可以
我的iPhone上就是用screen保持后台的.
