Re^3: Using grep and glob to find directories containing fileby BrowserUk (Patriarch) |

Since the first expression glob("$_/f*") is only true for 'dir1', it should only return that element of the directory list (even though glob returns 3 files in that directory). You are missing the fact that grep puts the glob in a scalar context, and that makes it act as an iterator: In scalar context, glob iterates through such filename expansions, returning undef when the list is exhausted.

In the absence of evidence, opinion is indistinguishable from prejudice.
