Shell Programming and Scripting

I do not know perl but need to know what the following conditional statement says. Can someone help ?

if (/ \S+@\S+\.\S+ accepted $| \S+\/\S+ accepted $/) {
next;
}
elsif (/ (\S+)\.\S+\.\S+\.\S+ \S+ \S+ \S+ \S+ \S+ (\S+)\.\S+\.(\S+)\.\S+ \S+ User (\S+) accepted $/) {
...


I think it says if some string separted by '@" plus some string and the word accepted OR some string separated with an '/' plus remaining string then skip ( next )
else some series of strings ( have no idea what all that means ) having User ( then something ???) and accepted then do processing ...
???
thanks

The first match looks like matching some email address or file path in a message.

The second matches some string delimited by . (dot). It should serve some extraction from fixed columns but I won't know what it is trying to match.

\S means a non-whitespace character, so anything other than tab, space, etc. will match. \. is a dot, and () means to backtrack a matched expression so that the matched content will be accessible in some later statements.

Actually, you should be able to find out more about Perl regular expressions in the perlre manpage.

thanks!

I suspect the '+" sign indicates one or more character or simply a string ?
