A shell solution to replacing a newline with another character is
to use the tr command which translates a single character into
another.  For example, cat forbar|tr '\012' ' '>tmp replaces
newlines in foobar with spaces and places output in tmp.  012
is the octal code for newline.  Other uses for tr include:
tr '[a-z]' '[A-Z]' translates lower to upper case
tr '()' '{}' translates open(close) parentheses to open(close)
             braces
