1、描述Linux发行版的系统目录名称命名规则以及用途。文件命名规则：文件名最长255个字符，包括路径在内文件名最长4095个字节，除了斜杠和NUL，所有字符都有效，但使用特殊字符的目录名不推荐使用，有些字符需要用引号来引用；标准linux文件系统，文件名称大小写敏感。 /bin：二进制程序，普通用户使用 /boot：引导文件存放目录，内核文件（vmlinux）、引导加载器（bootloader,grub）都存放于此目录 /dev：设备文件、特殊文件存放位置 /mnt：临时文件系统挂载点 /opt：第三方应用程序的安装位置 /srv：系统上运行的服务用到的数据 /lib：启动时程序依赖的基本共享库文件以及内核模块文件（/lib/modules） /etc：配置文件目录 /home：用户家目录 /root：root家目录 /sbin：二进制文件，管理员用户使用 /tmp：临时文件 /usr：类似根目录的目录结构 /var：存放可变化的数据 /proc：用于输出内核与进程信息相关的虚拟文件系统 /sys：用于输出当前系统上硬件设备相关信息虚拟文件系统 /selinux：selinux相关的安全策略等信息的存储位置 2、描述文件的元数据信息有哪些，分别表示什么含义，如何查看？如何修改文件的时间戳信息？元数据信息：文件类型、UID、GID、链接数、该文件的大小和不同的时间戳

问题 If I'm editing a file in Vim, then some external program changes the file, Vim tells me: W11: Warning: File "test.erl" has changed since editing started See ":help W11" for more info. [O]K, (L)oad File: If I L oad the file, though, all the undo history is lost. Is there any way to avoid that? 回答1: Update: it appears that this is one of the new features in Vim 7.3: https://groups.google.com/group/vim_announce/browse_thread/thread/66c02efd1523554b 回答2: I don't believe this is possible.

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: vim: copy selection to OS X clipboard While I succeeded to map paste from clipboard ( nmap <leader>p "*p ), the same for yank ( nmap <leader>y "*y ) doesn't seem working. Actually, it yanks in Vim's clipboard. Any idea how to do it properly? I know of clipboard=unnamed but I might keep the old yank/paste vim's commands. EDIT : It seems there is some confusion about my needs. The command "*y works . So there is

Vim: set langmap=e;h breaks supertab plugin

阅读更多关于 Vim: set langmap=e;h breaks supertab plugin

问题 I am new to Vim and trying to set up some plugins. So far I have installed pathogen, pyflakes and supertab. The latter does not seem to work; pressing tab while in insert mode simply writes the string <Plug>SuperTabForward . The problem only occurs with the following line in my vimrc (for better navigation using colemak layout): set langmap=hjklneiHJKLNEI;kniejhlKNIEJHL Without the above line it works just fine. After further experiments I've narrowed it down to set langmap=e;h . This single

问题 If I have a python file like: def Bar(): raise NotImplementedError def Foo(): Bar() if __name__ == '__main__': Foo() And I type :make in vim, it nicely builds me a :cwindow filled with the relevant areas to move up the traceback. However, it defaults my cursor to the first frame of the call (in name == ' main '). Can I somehow change the default behaviour, so it takes me to the actual call of the exception? -- Update -- Answering Ingo's question: :makeprg/errorformat are set to default for

What is the difference between BufRead and BufEnter?

阅读更多关于 What is the difference between BufRead and BufEnter?

问题 I am confused between the two events BufRead and BufEnter . What is the difference between them? Some example scenarios where I would choose one over the other would be greatly helpful. 回答1: A buffer is the in-memory representation of a file; to edit one, it has to be displayed in a window . The BufRead event is triggered after Vim has read the file into its memory. Unless you reload via :edit! , this only happens once. The BufEnter is fired whenever you activate a certain buffer, i.e. when

How to change tab titles in vim to user-define names?

阅读更多关于 How to change tab titles in vim to user-define names?

问题 I am using gvim for linux. I got a few tab pages open and a couple of windows open per tab page. I want to change the name of the tab pages to something significant to each project, as they are loaded separately in each tab. Normally tab pages are name after filenames, but I want to change them to specific project names. I tried to use set guitablabel , but it changes all the tabs not only the current one. 回答1: You can try something like this: fun! MyTabLabel() let s:title = gettabvar
