[VIM] reverse multiple lines in VIM

推荐方法：

If you’re on a Unix-like system (FreeBSD, Linux, macOS), use :14,19!tac.

To reverse the display order of lines 51 to 54 in Vim, you can use the :g and :tac-style command combination.

Here’s the most direct and idiomatic way to do it:

:51,54g/^/m51-1

Explanation

• :51,54 → selects lines 51 through 54.

• g/^/ → applies the following command (m51-1) to each line matching the regex ^ (i.e., every line in the range).

• m51-1 → moves the current line just before line 51.
  Because Vim executes this for each line in top-to-bottom order, the sequence is reversed.

Step-by-step result

Suppose lines 51–54 originally are:

line51
line52
line53
line54

After executing the command, they become:

line54
line53
line52
line51

Notes

• You can use :.,.+3g/^/m.-1 to do the same for “current line to current+3”. 这个方法，我尝试了下，没成功。

• Always use line numbers or marks ('a, 'b) to ensure the correct range.

Would you like me to show a macro-based or visual-mode method too (for more interactive editing)?

 

Another good ways:

 

To reverse lines 14 through 19 in Vim (i.e., make line 19 become 14, 18 become 15, etc.), you can do this directly from Normal mode with a range and an Ex command.

Here’s the precise command:

:14,19!tac

Explanation:

• : — enters command-line (Ex) mode.

• 14,19 — specifies the line range (lines 14 through 19).

• !tac — filters that range through the external Unix command tac, which reverses lines.

This will replace lines 14–19 with their reversed order.

If You’re on Windows (without tac):

Vim on Windows doesn’t have tac by default. You can simulate it using Vimscript:

:14,19g/^/m14

Explanation:

• g/^/ — matches all lines (from the specified range).

• m14 — moves each matched line after line 14, effectively reversing the block.

However: this command reverses relative to the top of the range, so if you start at line 14, it works cleanly.

Another Pure-Vim Method (portable across systems):

:14,19y a | 14,19d | put! a

Step-by-step:

1. :14,19y a — yank (copy) lines 14–19 into register a.

2. :14,19d — delete the original lines.

3. :put! a — put (paste) them reversed (the ! means before the current line, reversing the order).

That’s the most reliable Vim-only way.

✅ Recommendation:
If you’re on a Unix-like system (FreeBSD, Linux, macOS), use :14,19!tac.
If you want a Vim-only portable method, use the yank–delete–put trick.

Would you like me to give you a one-key macro that reverses any visually selected lines automatically?
