Ahhh ok brilliant. One more question.. why does this only print one column instead of the specified array range?I'm sure I'm doing something stupid but I can't find a good website or text with detailed stuff on specific command line perl

perl -lane '$,="\t";print $F[0..6]'  file.txt Thanks so much!

UPDATE Sorry, I got it, you just need to change the $ to a @ in front of F. Apologies
