Hi,
Hello,
I need to parse an ASCII file which first rows are comments. Those rows
are marked by a '#' at their beginning.
You need to use '^' instead of '\' to indicate the beginning of a line.
I try to filter them out by
while( <$FH> =~ m{\#*} )
{}
But this does not work. The loop does never stop.
What goes wrong? I am really confused!
Your pattern says to match zero or more of the '#' character and every line in
your file has at least zero '#' characters. You want something like:
1 while <$FH> =~ /^#/;
