説明

Is your feature request related to a problem? Please describe. On NixOS, process commands are always very long because everything is located in the Nix store under a cryptographically-hashed prefix (see screenshot). Even at a very high resolution (3840x1600 in my case) with btop maximized, and the left panel hidden, it's impossible to see the full command much of the time.

Describe the solution you'd like I'd like to be able to specify a prefix (maybe regex) to exclude some parts of the process command. For example, instead of /nix/store/<long string>/bin/.firefox-wrapped --name firefox, I could configure it to just show bin/firefox-wrapped --name firefox.

Describe alternatives you've considered Using a different distro would solve this but I don't wanna.

調査方針
The issue requests a feature to filter process command prefixes/regex. Related discussions in comments may provide implementation hints. Likely files to modify include process handling in btop's source code (e.g., src/btop.cpp or similar process listing modules). The maintainer should clarify the configuration format (e.g., in btop.conf). The feature could be implemented by adding a configuration option for prefix or regex to exclude parts of the command string before display.
