minus-squarelime!@feddit.nulinkfedilinkEnglisharrow-up17·11 hours agomy favorite awk snippet is !x[$0]++ which is like uniq but doesn’t care about order. basically, it’s equivalent to print_this_line = line_cache[$current_line] == 0; line_cache[$current_line] += 1; if $print_this_line then print $current_line end. really useful for those long spammy logs.
