[Bug 1971425] Re: The "look" cli dictionary only sees capitalized words

[Pragyansh Chaturvedi]

Hi
Turns out that util-linux is working as described in its manpage. I tried with the older implementation (bsdmainutils) too and the same issue persists. So the root cause is the default wordlist.
"look" expects the default wordlist to be sorted in a case-insensitive manner (which it was earlier) but now it is sorted in the ASCII order.
We can:
- Request the maintainers of wordlist to revert the way they sort the words (atleast wamerican)
- Supply our own wordlists to specifically make "look" work, but this will need to be in all supported languages and the default wordlist would change based on the locale of the user
- run a sort everytime (or better, the first time - but we will have to track change in locales) "look" is used in the default way.

Since the first two options are overkill for this, and the last option
can be easily done by the user (sort the exisiting
/usr/share/dict/words, save as another file, set that as the WORDLIST
env) than requiring a change in the util-linux package, I have moved
this bug to "Won't Fix"

  Digging deeper; the dictionary at /usr/share/dict/words seems OK.
  If I copy the "look" binary from Ubuntu 20.04 and use it on Ubuntu 22.04 it works;
  ~ > ./look accident
  accident
  accidental
  accidentally
