Try this in an empty directory and let me know if this is a bug or a feature
or an error on my part.
Create several files of upper and lower case names:
touch aaaa
touch AAAA
touch bbbb
touch BBBB
touch 1234
touch .abcd
Now use a regular expression to delete all files starting with a lower case
letter:
rm [a-z]*
When I was experimenting with this all of the files starting with *any*
alphabetic character were deleted. This was unexpected and I'm not sure if
I am misinterpreting the regular expression or if I am delusional. Let me
know what you get. FYI, I am using Red Hat Linux 7.2 so I would be
interested if it's just me.
