====Using Simple "Wildcards" and "Repetitions"====
Calling these "wildcards" may actually conflict with the theoretical grammar and syntax of Perl, but in fact is the most intuitive way to think of it, and will not lead to any coding mistakes.
. Match any character
\w Match "word" character (alphanumeric plus "_")
\W Match non-word character
\s Match whitespace character
\S Match non-whitespace character
\d Match digit character
\D Match non-digit character
\t Match tab
\n Match newline
\r Match return
\f Match formfeed
\a Match alarm (bell, beep, etc)
\e Match escape
\021 Match octal char ( in this case 21 octal)
\xf0 Match hex char ( in this case f0 hexidecimal)
You can follow any character, wildcard, or series of characters and/or wildcard with a repetiton. Here's where you start getting some power:
* Match 0 or more times
+ Match 1 or more times
? Match 1 or 0 times
{n} Match exactly n times
{n,} Match at least n times
{n,m} Match at least n but not more than m times
Now for some examples:
$string =~ m/\s*rem/i; #true if the first printable text is rem or REM
$string =~ m/^\S{1,8}\.\S{0,3}/; # check for DOS 8.3 filename
# (note a few illegals can sneak thru)
