I have a file of data that I want to safety check to ensure that there is data for each piece of the line being split. Is there a fast way to say "If any of these are '' then write to error log"?
Assuming you store the data in an array, you can simply say:
if (grep length == 0, @data_members) { print LOG "error: empty fields found in this dataset\n"; }
Something to that effect should work.
follow-up question: will this only be true if $item of @array is completely empty? This is the type of data for each $item of @array:
ID, name_f, name_l, email, id, contact, group, member
I am splitting this by commas into different $scalers to manipulate. And I know that same of these fields are empty (to which I need to report back to the people sending me the data). It will NEVER happen that a whole line is empty, but just one or two of the fields in each line.
Does that change the scope of this suggestion?
