I know "/" is a special character for regex, which should be escaped.
But if I put "/" in a variable and use the variable in regex, then it
doesn't need the explicit escape. Like this one:
$ perl -le '$delimiter="/"; $str="hello/world/buddy";
@list=split/$delimiter/,$str;print "@list"'
hello world buddy
Am I right? thank you.
"/" is NOT a special charater in a regular expression. It is just that
in Perl the default delimiter for some operators is "/" (i.e. m//, s///,
tr///, etc.).
