How do I fix that? One way would be to check the return value of ls using the $? built in variable. eg in my home directory, i have a file "foo", but not one called "bar": $ ls foo foo $ echo $? 0 $ ls bar ls: cannot access bar: No such file or directory $ echo $? 2 So, when $? is not 0, simply echo filename > somefile.
