I’m trying to replace each
, in the current file by a new line:
But it inserts what looks like a
^@ instead of an actual newline. The file is not in DOS mode or anything.
What should I do?
If you are curious, like me, check the question Why is r a newline for Vim? as well.
r instead of
n inserts a null character into the text. To get a newline, use
r. When searching for a newline, you’d still use
n, however. This asymmetry is due to the fact that
r do slightly different things:
n matches an end of line (newline), whereas
r matches a carriage return. On the other hand, in substitutions
n inserts a null character whereas
r inserts a newline (more precisely, it’s treated as the input CR). Here’s a small, non-interactive example to illustrate this, using the Vim command line feature (in other words, you can copy and paste the following into a terminal to run it).
xxd shows a hexdump of the resulting file.
echo bar > test (echo 'Before:'; xxd test) > output.txt vim test '+s/b/n/' '+s/a/r/' +wq (echo 'After:'; xxd test) >> output.txt more output.txt
Before: 0000000: 6261 720a bar. After: 0000000: 000a 720a ..r.
In other words,
n has inserted the byte 0x00 into the text;
r has inserted the byte 0x0a.
