Package: bsdextrautils Version: 2.36-3+b1 look's behavior became really unpredictable when it migrated from bsdmainutils to util-linux.
$ look achi Achille Achille's Achillean Achilles Achilles's Achitophel $ grep -ci ^achi /usr/share/dict/words 36 $ This is just one example but sometimes it works and sometimes it doesn't. It tends to behave consistently for a given prefix, but if it chooses capitalized words or not varies (locale makes no difference that I can see). eg: $ look cra | wc -l 518 $ grep -ci ^cra /usr/share/dict/words 609 $ diff -u <(grep -i ^cra /usr/share/dict/words) <(look cra) | head --- /dev/fd/63 2020-10-31 08:00:51.587099984 +0000 +++ /dev/fd/62 2020-10-31 08:00:51.587099984 +0000 @@ -1,94 +1,3 @@ -Crabbe -Crabbe's -Craborchard -Craborchard's -Crabtree -Crabtree's -Cracker -- Jamie Heilman http://audible.transient.net/~jamie/
