unique-filename
Generate a unique filename for use in temporary directories or caches.
uniqueFilename(dir, fileprefix, uniqstr) → String
Returns the full path of a unique filename that looks like: dir/prefix-7ddd44c0
or dir/7ddd44c0
dir – The path you want the filename in. os.tmpdir()
is a good choice for this.
fileprefix – A string to append prior to the unique part of the filename. The parameter is required if uniqstr is also passed in but is otherwise optional and can be undefined
/null
/''
. If present and not empty then this string plus a hyphen are prepended to the unique part.
uniqstr – Optional, if not passed the unique part of the resulting filename will be random. If passed in it will be generated from this string in a reproducable way.
