Re: Wildcards - open a file with one unknown digital character

By the way, escaping _ and - is unnecessary in string literals, in regex patterns and in glob patterns. Escaping them is just visually confusing.

Also, by simply appending : $! to your error message, you make it far more useful.

Thank you for the hints. I escaped _ because of the scalars containing _ in their names. if I use my @cachefiles = glob("/home/cache/_$scalar_1_2"); it does not recognize $scalar_1 I'd have to write my @cachefiles = glob("/home/cache/_$scalar_1\_2");	[reply]

`"...${scalar}_..."` [download] would also do. The curly method also works where a slash wouldn't. `"...${abc}def..."` [download]	[reply] [d/l] [select]
