I have a script in ~/bin called go_refresh. It's definitely there. I run fswatch like so:
fswatch -o /usr/local/var/www/wp_sites/test/wp-content/themes/test/style.css | xargs -n1 -I{} ~/bin/go_refresh
When I change the file, I get this error once:
xargs: /Users/my_dir/bin/go_refresh: No such file or directory
And the script doesn't run.
