Xterm：找不到 shell 的绝对路径：500

Question

在 SSH（使用启用 X11 的腻子）进入我的虚拟机 VM 后，我尝试打开一个 xterm 窗口。但是以下命令：

xterm -sb 500

甚至

/usr/bin/xterm -sb 500

返回错误：

xterm: No absolute path found for shell: 500

我似乎无法弄清楚错误的含义！

编辑：

ls -la /usr/bin/xterm
-rwxr-xr-x 1 root root 450888 Sep 28  2012 /usr/bin/xterm

alias xterm
-bash: alias: xterm: not found

Answer 1

也许你的意思是

xterm -sl 500

该-sb选项不使用任何值。

这些选项的手册页：

   -sb     This  option  indicates  that  some  number  of  lines that are
           scrolled off the top of the window should be saved and  that  a
           scrollbar  should  be  displayed  so  that  those  lines can be
           viewed.  This option may be turned on  and  off  from  the  "VT
           Options" menu.

和-sl选项：

   -sl number
           This option specifies the number of lines  to  save  that  have
           been  scrolled  off the top of the screen.  This corresponds to
           the saveLines resource.  The default is "64".
