Use #!/usr/bin/env for bash shebangs. /bin/sh and /usr/bin/env are the only two binaries that NixOS provides at a fixed path (outside a buildFHSUserEnv sandbox). This discussion was split from #11004. Signed-off-by: Anders Kaseorg <andersk@mit.edu> 2018-12-18 02:08:53 +01:00			`#!/usr/bin/env bash`

tools: Convert fix-unused-css to look at zulip.scss. This tool is hackish and incomplete, but it's still worth looking at if somebody wants to hunt down obsolete CSS. There are probably better ways to tackle this problem, so we should eventually just remove this tool, but it's pretty low maintenance.
