This is line one.
This is line two.
This is line three.

#If you indent your string with tabs (i.e., '\t'), the indentation will be stripped out. If you indent with spaces, the indentation will be left in.
#NOTE: It is significant that the last closing parenthesis is on another line. The END text must appear on a line by itself.# You may use echo:
echo "this is line one" \
"\n""this is line two" \
"\n""this is line three" \
> filename
#It does not work if you put "\n" just before \ on the end of a line.
# Alternatively, you can use printf for better portability (I happened to have a lot of problems with echo):
printf '%s\n' \
"this is line one" \
"this is line two" \
"this is line three" \
> filename
# Yet another solution might be:
text=''
text="${text}this is line one\n"
text="${text}this is line two\n"
text="${text}this is line three\n"
printf "%b" "$text" > filename
#or
text=''
text+="this is line one\n"
text+="this is line two\n"
text+="this is line three\n"
printf "%b" "$text" > filenameecho | tee /tmp/pipetest << EndOfMessage
