In mac osx, I'm trying to write a spinner that takes in a command and spins while running it
The usage would be for long commands called from the command line programatically. In my case php will be calling yarn update. If there is a space in the command I can't figure out how to run it.
I've been looking at the following
alias spin='{ f=$(cat -);
eval $f;
while [ -n "$(ps -p $! -o pid=)" ]; do
echo -n ".";
sleep 1;
done
}<<<'
or
alias spin2='eval $*; echo $*; echo $!;
while [ -n "$(ps -p $! -o pid=)" ]; do
echo -n ".";
sleep 1;
done;
echo "all done"'
using zsh on macos mojave
the usage for testing would be spin sleep 4
or spin yarn install
not much of a spinner, I started off that way but I'd go for anything simple at the moment hence the dots.
cheers and thanks
