VIM: how to go to exact line on Ubuntu
提问by kevin
I'm using vion Ubuntu 12.10. Some files are quite long so when I want to go to the middle of the file, I have to page down or scroll down.
我vi在 Ubuntu 12.10 上使用。有些文件很长，所以当我想转到文件中间时，我必须向下翻页或向下滚动。
Is there a VIM shortcut to go to an exact line number?
是否有 VIM 快捷方式可以转到确切的行号？

:150
will take you to line 150 in vi
将带您到 vi 中的第 150 行
:1500
will take you to line 1500 in vi
将带您到 vi 中的第 1500 行
As per the comments you may want to try
根据您可能想尝试的评论
150G
150G
to get to line 150. which is less key strokes then :150Enterif you aren't sure what line you are on try
到第 150 行。:150Enter如果你不确定你在哪一行，那么击键次数更少
:set nu!
notice the :
注意：
if you want to always see the line consider editing your vim profile. Most often
如果您想始终看到该行，请考虑编辑您的 vim 配置文件。最经常
vi ~/.vimrc
and add
并添加
:set nu!
and write and quit
写然后退出
:wq
#or you could use :x
this can be done outside of vi. For example, if I want to delete line 5000 in a text file I could use a scripting language. For example, using sed it would be the following
这可以在 vi 之外完成。例如，如果我想删除文本文件中的第 5000 行，我可以使用脚本语言。例如，使用 sed 将是以下内容
sed -i '5000d;' inputFile.txt
to delete line 10 to 20 it would be
删除第 10 到 20 行，它将是
sed -i '10,20d;' inputFile.txt
notice the -i will edit the file in place. Without the -i it will goto stdout. Try it. you can redirect stdout to a file
注意 -i 将就地编辑文件。没有 -i 它将转到标准输出。尝试一下。您可以将标准输出重定向到文件
sed '5001,$d;' inputFile.txt >> appenedFile.txt
this might have a lot going on here for you. this deletes line 5001 to $. With $ being the end of the file. >> will append to a file. where as > creates a new file.
这对你来说可能有很多事情要做。这会将第 5001 行删除为 $。$ 是文件的结尾。>> 将附加到文件。其中 as > 创建一个新文件。
if you are curious how many lines are in a file you may want to type wc -l inputFile.txt
如果您想知道一个文件中有多少行，您可能想输入 wc -l inputFile.txt
some of this may seem awfully trivial, but if you are trying to edit a file with 50,000 lines it may take vi a sweet minute to open and traverse. where if you know you just want to delete the last line you could use sed and do it in a fraction of the time.
其中一些可能看起来非常微不足道，但是如果您尝试编辑一个包含 50,000 行的文件，则可能需要花费一分钟才能打开和遍历。如果您知道只想删除最后一行，则可以使用 sed 并在很短的时间内完成。
sed can also search and replace inside a file as well. But perhaps awk, perl, or python might also be a viable solution.
sed 也可以在文件内搜索和替换。但也许 awk、perl 或 python 也可能是一个可行的解决方案。
but overall, you may wan to find a good tutorial on vi. thousands exist. I'd consult google. Perhaps find yourself a VIM Cheatsheat.
但总的来说，你可能想找到一个关于 vi 的好教程。数以千计的存在。我会咨询谷歌。也许发现自己是一个 VIM 秘籍。

From an opened terminal, in a bash shell, simply edit your file by running:
在打开的终端中，在 bash shell 中，只需通过运行以下命令来编辑您的文件：
$ vi +N yourfile
Where Nis the line number.
N行号在哪里。
For viewing (moreor less;):
用于查看（more或less;）：
$ less +N yourfile
$ more +N yourfile
The sign +mean command to run at start. So if commandis only a number, then vi, lessand more, will jumps to this as line number.
符号+表示在 start 时运行的命令。因此，如果command只是一个数字，则vi, lessandmore将作为line number跳转到此。
But you may also use /regexfor finding the first occurence of a specific string or regex:
但您也可以/regex用于查找特定字符串或正则表达式的第一次出现：
$ less +/Error logfile
$ less -i +/error logfile # -i Causes less's searches to ignore case
$ vi +/open.*myfile myprog...
