How can I make sed not append a newline character to an input stream that was missing one? If I can't, what's the quickest way to remove a newline character from a variable?A code sample was requested in the comments, so here you go. Imagine a .csv file that has no newline at the end. Pipe it into a script. Then inside that script:function foobarize() {    sed \    -e s|foo|bar|g \    $1}INPUT=`tee`printf $INPUT | foobarizeIf the input has no newline at the end, foobarize will add a newline to it 100% of the time.
