I don't really have an answer, but conceptually, why would you need
a -e test at all? If the file doesn't exist, how would wanted() get
called for it?
Also, have you tried doing the -e on $File::Find::name instead of $_ ?
Perhaps there's some problem in changing directories.
Hi Bob,
Thanks for the response! Good question: My original code - which produced
the same results - used the -f test because I don't want to include
directories in my final output. I don't think the problem is with changing
directories, because within a given directory, some files will be listed
and others will be omitted.
Thanks!
