If you accidentally create a filename that contains a nonprinting character, such as a CONTROL character, how can you remove the file?
What will be an ideal response?
Use some unique characteristic of the filename along with wildcard charac-
ters to specify the file. Confirm the ambiguous file reference works by using
echo before you attempt to use it with rm. For example, assume you want
to remove the file named abCONTROL-Txyz. The following commands test an
ambiguous file reference to make sure it does not refer to any other files and
then remove the file using the reference
$ echo ab?xyz
abxyz
$ rm ab?xyz
