I wanna search a string "*********" and I remember some special characters
can be used to tell the match so I need not type something like:

\*\*\*\*...

Would anybody know how to do that?

See \Q in "perldoc perlre".

(1) See jue's hint
(2) use the ...{}-quantifier, eg.

/\*{5}/

to match exactly 5 asterisks, or

/\*{2,7}/

to match two up to seven of them.


Again, read
perldoc perlre

Or, if you are backslash-averse as I am, you can write it as:

/[*]{5}/

Yes, but in Perl before 5.10 the backslashed version is more efficient.
