Question

How do I delete files within a temp folder at only have the .jpg extension.

Here is what I tried;

unlink("../httpdocs/Temp/*.jpg);

Answer 1

You need to apply the glob function to the pattern, for example:

unlink glob "../httpdocs/Temp/*.jpg";

This is covered in the unlink and glob docs. Unlink itself expects a list of files to process. The glob function will, to quote the docs:

In list context, returns a (possibly empty) list of filename
expansions on the value of EXPR such as the standard Unix shell
/bin/csh would do.
