Bash script echo seems to remove my new lines? [duplicate]

问题

This question already has answers here:

I just assigned a variable, but echo $variable shows something else (7 answers)

Closed 2 years ago.

This is the contents of my file file.txt:

header
a
b
c

I have no idea what is going on. This command does not print new lines.

echo -e $(tail -n +2 file.txt)

This prints:

a b c

But if you write it to file you will clearly see new lines:

tail -n +2 file.txt >> new_file.txt

test.txt

a
b
c

How do I force echo to print the new lines? I don't think I can use printf here without making some kind of loop.

回答1:

Echo statement within quotes give your output with newline terminated lines. Here is the code

echo -e "$(tail -n +2 file.txt)"
