just curious, what's the difference (in speed or results) between this
and 'dis/a/s/b *.mp3'?
obviously File::Find and perl are more powerful, but that doesn't seem
like the right use case for it?
Hi Shawn,
Good point... For a simple printing of results, 'dir' is noticeably
faster and gives the same results. Actually, before I learned how to
use File::Find, I used to pipe the output from 'dir' to perl to filter
results with a regex:
dir /s /b | perl -wnle "/regex/ and print;"
...essentially using perl as 'grep', and it's faster than the File::Find
solution (well, I don't have benchmarks to prove it, but File::Find
seemed slower to me). Although in my rather basic uses, the performance
difference is inconsequential, and either way beats using the Windows
"Search Companion".
