Re: Spliting file + removing column

Just a quick side note. This

@row = $row; (@row[0],@row[1],@row[2], @row[3], @row[4], @row[5], @row[6])=split(/\ +s+/,$row);
[download]

is more compactly written as

my @row = split(/\s+/,$row);
[download]

(Strictly speaking, the latter would create more than 7 array elements, in case there are more fields in the input — but you only seem to have 6 anyway. The direct equivalent would be @row = (split /\s+/,$row)[0..6];)

Also, @row[3] (i.e. an array slice with a single element) is generally better written as $row[3].

...it's not the same. In other words, it depends on what the OP wants. `split ' '` is "magic" in that it ignores leading white space, while `split /\s+/` does not.	[reply] [d/l] [select]
