Printf example in bash does not create a newline
- by WolfHumble
Working with printf in a bash script, adding no spaces after "\n" does not create a newline, whereas adding a space creates a newline, e. g.:
No space after "\n"
NewLine=`printf "\n"`
echo -e "Firstline${NewLine}Lastline"
Result:
FirstlineLastline
Space after "\n "
NewLine=`printf "\n "`
echo -e "Firstline${NewLine}Lastline"
Result:
Firstline
Lastline
Question: Why doesn't 1. create the following result:
Firstline
Lastline
I know that this specific issue could have been worked around using other techniques, but I want to focus on why 1. does not work.
