Problem
My initial guard against setting up multiple
fswatchinstance ran into some race conditions.Solution
Use
pidofinstead of grepping through ps looking for an existing process.Caveats
This can still run multiple instance if the script is started from different directories. As an example:
toolsdirectory (tools/dart_version_watcher.sh)$HOME/.asdf/plugins/dart/tools/dart_version_watcher.sh)I don't know why anyone would do that so I'm not going to worry about it for now.
