我知道使用vim -R从shell以只读模式打开文件，但是如何以只读模式在单独的选项卡（:tabe <filename>）中从vim内部打开文件？
感谢您的时间。
答案 0 :(得分：71)
要在新标签页中以只读模式打开文件，请使用
tab sview /path/to/file
要在同一窗格中打开文件（不使用新窗口或标签页），请使用
view /path/to/file
请注意，tab view /path/to/file 不会打开新标签页。
答案 1 :(得分：31)
您可以从vim内部以只读模式打开文件：
:view /path/to/file
或从命令行：
$ vim -M /path/to/file
答案 2 :(得分：19)
vim -M filename以只读模式打开文件。
答案 3 :(得分：14)
使用:tabe <filename>打开文件，然后输入:view。它将自动切换到只读模式。
答案 4 :(得分：4)
尝试:tabedit +set\ noma|set\ ro FILE;这将在FILE关闭且modifiable打开的新标签页中打开readonly，从而阻止您修改或编写文件。如果您只想readonly，请省略noma集。可能很方便将其重新映射到另一个命令。
答案 5 :(得分：3)
vim -R /path/to/file
vim -m /path/to/file
只读模式。 允许修改文本但不能写（不保存）。
vim -M /path/to/file
不允许修改文本。

--How to get "parentkey" in the stored procedure perfectly??
--The procedure furnishes wrong results if more than 1 same parent is addded in --same/different level of bom. The results shows one parent for all childs.
