Hackery World disintermediation, one hack at a time Gavin Carr « Older posts GNU sort traps with field separators Sat 06 Nov 2021 Tags: linux , sysadmin GNU sort is an excellent utility that is a mainstay of the linux command line. It has all kinds of tricks up its sleeves, including support for uniquifying records, stable sorts, files larger than memory, parallelisation, controlled memory usage, etc. Go read the man page for all the gory details. It also supports sorting with field separators, but unfortunately this support has some nasty traps for the unwary. Hence this post. First, GNU sort cannot do general sorts of CSV-style datasets, because it doesn’t understand CSV-features like quoting rules, quote-escaping, separator-escaping, etc. If you have very simple CSV files that don’t do any escaping and you can avoid quotes altogether (or always use them), you might be able to use GNU sort - but it can get difficult fast. Here I’m only interested in very simple delimited files - no |
