Bash: Why is echo adding extra space?

Question

I get:

$ echo -e \"D\"{a,b,c}\".jpg\\n\"
Da.jpg
 Db.jpg
 Dc.jpg

Note: The extra spaces before Db and Dc on the 2nd and 3rd line of the outp

Answer 1

Here is a solution using sed (that builds upon https://stackoverflow.com/a/2003856/8180143):

$ echo -en "" "D"{a..c}".jpg\n" | sed 's/ //'
Da.jpg
Db.jpg
Dc.jpg

This solution has the advantage of working with inputs having spaces, e.g.,

$ echo -en "" "D "{a..c}".jpg\n" | sed 's/ //'
D a.jpg
D b.jpg
D c.jpg
