Use the $P form above.
If you are using Perl you can use the following little
gem that was sent to me by somebody:
my(%options);
while( <> ){
chomp line;
%options=();
while( s/ [-']+(\w)'*([^']+)'//g ){
$options{$1}=$2;
}
if( /start/ ){
#handle the start stuff
} elsif( /end/ ){
#handle the end stuff
}
}
If you want to pull just one out, you can use:
$value = $1 if / [-']+X'*([^']+)'/;
where X is the letter corresponding to the option.
This is one of the reasons I love Perl so much.
Perl: No two users do it the same way.
If you are using C, then you can use:
while( fgets(input, strbuf, sizeof(strbuf) ){
if( (s = strchr(strbuf,'\n')) ) *s = 0;
for( s = strbuf; s && ( (s = strstr( s, " -'")) || (s = strstr( s, " '-")) ); s =
t ){
s += 3;
if( (t = strchr(s,'\'') ){
*t++ = 0;
}
c = *s++;
/* now you have c == option and s -> the option value */
... and you handle the options the way you want
}
}

No, no. You ask GOOD questions. And you read the manual!
