When running 'look' to get all comments in a file I only get the first found line in the ouput. Can someone explain this?
look "#" .zshrc
There are really a lot more comments (lines starting with '#') in my .zshrc then the first line.
- dmd 11y agoYour .zshrc is almost certainly not a sorted file.
- kbd 11y agoFrom the manpage: > As look performs a binary search, the lines in file must be sorted... I assume you didn't sort your source file first.
- hanez 11y agoWhen sorting the file first I get no output anymore: sort ~/.zshrc -o /tmp/.zshrc look "#" /tmp/.zshrc Sorry for the noise but I am confused... :|

- emmelaich 11y agosort(1) might not use the same ordering as look(1) Try setting LC_COLLATE=C and export it and retry.
- hanez 11y agoUh, wow! That was it! Thanks for this answer...
- andreasvc 11y agoIt doesn't make sense to sort a configuration file, order and context matters. Easier to just use grep '^#' (or even better, ag).
- hanez 11y agoYes, I am aware of that but I wanted to understand the usage of 'look' at this point. It was a fault to try stuff using the .zshrc file at first because I ran into misunderstanding everything. It was just the first file that came in mind to me. Since sorting a source file and then "looking" for comments makes no sense in any way, grep seems to be really the better choice.
