如果在Mac上使用iTerm2，有一种更简单的方法。该功能通过it2copy命令内置到iTerm2的Shell集成功能中:

Usage: it2copy
          Copies to clipboard from standard input
       it2copy filename
          Copies to clipboard from file

要使其工作，请在登录到远程主机时选择iTerm2—>Install Shell Integration菜单项，将其安装到您自己的帐户中。完成此操作后，您就可以访问it2copy以及其他一些别名命令，这些命令提供了很酷的功能。

这里的其他解决方案都是很好的变通方法，但相比之下，这个解决方案非常简单。

最简单的解决方案，如果你在OS X上使用Terminal，并且你已经在远程服务器上ssh了，并且希望获取文本文件或日志或csv的结果，简单地:

1) Cmd-K清除终端输出

2) cat <filename>显示文件的内容

3) Cmd-S保存“终端输出”

你需要手动删除文件的第一行和最后一行，但这种方法比依赖其他要安装的包、“反向隧道”和尝试使用静态IP等要简单一些。

有各种工具可以访问X11选择，包括xclip和XSel。注意，X11传统上有多个选择，大多数程序对剪贴板和主选择都有一定的理解(这是不一样的)。Emacs也可以使用二级选择，但这是罕见的，没有人真正知道如何处理剪切缓冲区…

$ xclip -help
Usage: xclip [OPTION] [FILE]...
Access an X server selection for reading or writing.

  -i, -in          read text into X selection from standard input or files
                   (default)
  -o, -out         prints the selection to standard out (generally for
                   piping to a file or program)
  -l, -loops       number of selection requests to wait for before exiting
  -d, -display     X display to connect to (eg localhost:0")
  -h, -help        usage information
      -selection   selection to access ("primary", "secondary", "clipboard" or "buffer-cut")
      -noutf8      don't treat text as utf-8, use old unicode
      -version     version information
      -silent      errors only, run in background (default)
      -quiet       run in foreground, show what's happening
      -verbose     running commentary

$ xsel -help
Usage: xsel [options]
Manipulate the X selection.

By default the current selection is output and not modified if both
standard input and standard output are terminals (ttys).  Otherwise,
the current selection is output if standard output is not a terminal
(tty), and the selection is set from standard input if standard input
is not a terminal (tty). If any input or output options are given then
the program behaves only in the requested mode.

If both input and output is required then the previous selection is
output before being replaced by the contents of standard input.

Input options
  -a, --append          Append standard input to the selection
  -f, --follow          Append to selection as standard input grows
  -i, --input           Read standard input into the selection

Output options
  -o, --output          Write the selection to standard output

Action options
  -c, --clear           Clear the selection
  -d, --delete          Request that the selection be cleared and that
                        the application owning it delete its contents

Selection options
  -p, --primary         Operate on the PRIMARY selection (default)
  -s, --secondary       Operate on the SECONDARY selection
  -b, --clipboard       Operate on the CLIPBOARD selection

  -k, --keep            Do not modify the selections, but make the PRIMARY
                        and SECONDARY selections persist even after the
                        programs they were selected in exit.
  -x, --exchange        Exchange the PRIMARY and SECONDARY selections

X options
  --display displayname
                        Specify the connection to the X server
  -t ms, --selectionTimeout ms
                        Specify the timeout in milliseconds within which the
                        selection must be retrieved. A value of 0 (zero)
                        specifies no timeout (default)

Miscellaneous options
  -l, --logfile         Specify file to log errors to when detached.
  -n, --nodetach        Do not detach from the controlling terminal. Without
                        this option, xsel will fork to become a background
                        process in input, exchange and keep modes.

  -h, --help            Display this help and exit
  -v, --verbose         Print informative messages
  --version             Output version information and exit

简而言之，您应该尝试xclip -i/xclip -o或xclip -i -sel clip/xclip -o -sel clip或xsel -i/xsel -o或xsel -i -b/xsel -o -b，这取决于您想要什么。

这是我基于SSH反向隧道、netcat和xclip的解决方案。

首先创建脚本(例如:Clipboard-daemon.sh)

#!/bin/bash
HOST=127.0.0.1
PORT=3333

NUM=`netstat -tlpn 2>/dev/null | grep -c " ${HOST}:${PORT} "`
if [ $NUM -gt 0 ]; then
    exit
fi

while [ true ]; do
    nc -l ${HOST} ${PORT} | xclip -selection clipboard
done

然后在后台启动。

./clipboard-daemon.sh&

在接收到部分数据后，将开始数控管道输出到xclip和重生过程

然后启动ssh连接到远程主机:

ssh user@host -R127.0.0.1:3333:127.0.0.1:3333

当登录在远程框上时，尝试这样做:

echo "this is test" >/dev/tcp/127.0.0.1/3333

然后在您的工作站上尝试粘贴

当然，您可以编写包装器脚本，首先启动clipboard-daemon.sh，然后启动ssh会话。这就是我的工作方式。享受。

我最喜欢的方法是ssh [remote-machine] "cat log.txt" | xclip -selection c.当你不想(或不能)从远程ssh到本地时，这是最有用的。

编辑:在Cygwin ssh [remote-machine] "cat log.txt" > /dev/clipboard. txt

编辑:来自nbren12的有用评论:

几乎总是可以使用ssh端口转发建立反向ssh连接。只需将RemoteForward 127.0.0.1:2222 127.0.0.1:22添加到本地.ssh/config中的服务器条目中，然后在远程计算机上执行ssh -p 2222 127.0.0.1，然后将连接重定向到本地计算机。——nbren12

@rhileighalmgren解决方案很好，但pbcopy会烦人地复制最后一个“\n”字符，我使用“head”剥离最后一个字符来防止这种情况:

#!/bin/bash
head -c -1 |  ssh desktop pbcopy
