    Pipelines of many simple tools (specifically the mentioned ones, like head, tail, grep, sort, cut, tr, sed, ...) are often used unnecessarily, specifically if you already also have an awk instance in that pipeline which can do the tasks of those simple tools as well. Another issue to be considered is that in pipelines you cannot simply and reliably pass state information from processes at the front side of a pipeline to processes that appear on the rear side. If you use for such pipelines of simple programs an awk program you have a single state space. Commented Mar 3, 2015 at 5:54

    Setting LC_ALL is over-used, as it overrides all possible locale settings, not just the ones that affect input parsing. To make sure that sort works consistently, LC_COLLATE=C is the appropriate setting. That said, LC_ALL=C.UTF-8 has identical sorting as C, and doesn't break tools that need to treat Unicode characters as such. Commented Jun 30, 2022 at 12:21
