(replying to several)
Thank-you everyone that replied.
This is the first bash script I've tried to write in about 8 years.
The '$' in front of the variable in the left side of the assignment was
definitely an error. Removing it eliminated an error message. Thank-
you, everyone. But that's not the real focus of this thread. The real
problem is how to do this:
string2=
string1
concatenated_to
more_than_one_space
concatenated_to
string2
(I wish bash had an explicit string concatenation operator!)
Why does this work:
onespace=" "
longstring=${startstring}${onespace}${onespace}${onespace}${longstring}
echo "longstring = \"$longstring\"."
but this not work:
longstring=${startstring} ${longstring}
echo "longstring = \"$longstring\"."
The things on the right are considered parameters and extra spaces are
removed. You need to quote it as mentioned by others.
longstring="${startstring} ${longstring}"
That will keep all the spaces in between.
