Just so you understand how the quoting works here: you can't escape single
quotes with backslashes inside a single-quoted string. The \'cowrite.*\'
ends the first single-quoted string and inserts a single quote into the
command, since the backslash acts as an escape character in an unquoted
context. The double quote after -delete starts a new double-quoted string,
which is not terminated when the shell reaches the end of the script.
