Actually, the correct question would be: how do I run a bash script when a USB stick is mounted ? Which is doable via Task Scheduler and a event log trigger. See https://answers.microsoft.com/en-us/windows/forum/windows_vista-windows_programs/task-scheduler-how-to-automatically-synchronize-my/45a49d83-b1d8-4d37-8896-3d2696cf9795 on how to locate the appropriate event, As for the script: - don't use ls for checking file/directory presence use -f/-d (man test) - you will need to adjust paths (cygwin has windows drives under /cygdrive (cygpath -h) On how to run the script from Task Scheduler use an action like this: C:\Tools\cygwin64\bin\bash.exe -c /cygdrive/c/tools/cygwin64/home/bryan/bkp.sh (adjust your paths accordingly ) > > > > -- > cyg Simple > > -- > Problem reports: http://cygwin.com/problems.html > FAQ: http://cygwin.com/faq/ > Documentation: http://cygwin.com/docs.html > Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple > -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
