在Vim中，将文件中的所有行连接成一行的最简单方法是什么？

Question

I want to join all lines in a file into a single line. What is the simplest way of doing this? I've had poor luck trying to use substitution ( \\r\\n or \\n doesn't seem to get picked up correctly in the case of s/\\r\\n// on Windows). Using J in a range expression doesn't seem to work either (probably because the range is no longer in 'sync' after the first command is executed).

I tried :1,$norm! J :1,$norm! J but this only did half of the file - which makes sense because it just joins each line once.

Answer 1

Another way:

ggVGJ

" ggVG " visually selects all lines, and " J " joins them.

Answer 2

Ah, I found the answer.

:1,$join

Works like a charm.

EDIT : As pointed out in the comment:

:%join   -or-    :%j

...removes the range.

Answer 3

You can do it with 3 keystrokes starting from normal mode:

:%j

• : enters command mode
• % refers to all lines in the file
• j executes the join command

Now it seems that this adds a space between the lines. I am not sure if you want this.

Answer 4

You can do it in three fewer keystrokes:

:1,$j

isn't ed grand?

Answer 5

Cryptic way:

qqqqqJ@qq@q

(the first three q 's clear the q register, the qqJ@qq records a macro to the q register that performs a Join, then calls q , and the last @q runs it.

Answer 6

I'm surprised no one even mentioned the other way:

:%s/\n/ /

I am equally surprised that no one pointed out that the range 1,$ has a shorthand that's written % .

(This doesn't do the same thing as joining the lines, but depending on circumstances that may in fact be more appropriate.)
