Thanks Jean - `nohup` is the solution.
I changed your scripts a bit, so that the starts is restarting quarto if it
is running:
#!/bin/bash
pid=$(ps -A -mm | grep -v grep | grep "quarto.js preview ${BB_DOC_PATH}" |
awk '{print $1}')
if [ -z "$pid" ]; then
pkill -F "$pidfile"
fi
nohup quarto preview "$BB_DOC_PATH" >& /dev/null &
and to stop:
#!/bin/bash
pid=$(ps -A -mm | grep -v grep | grep "quarto.js preview ${BB_DOC_PATH}" |
awk '{print $1}')
kill -9 $pid
Thanks a lot for your input,
Rainer
