ok, I ran your script as sudo in the ssh console: in the GUI I see the external hdd gets mounted, however, the script stops at 'waiting for the
filesystem to mount'. Apparently, kern.log doesn't output the 'mounted successfully' option:
Any ideas?
Also, un-mounting (=ejecting) the device via the GUI just adds one single line to kern.log:
so I suppose the next part of the script also won't recognize unmounting the hdd
Also, don't you need to put
exec 3< <(tail -f -n1 /var/log/kern.log)
in front of
echo -n "Waiting for filesystem to unmount... " while read line; do if [[ "$line" = *"[EXFAT] unmounted successfully" ]]; then echo "Unmounted!" break; fi done <&3
, as well, in order to read the kern.log?
Thanks!
The script here relies on the log from kernel, and it apparently supports only exFAT filesystem. I have no idea about your system and external disk so I can't really provide any advice. There is probably a better way to detect mounting and unmounting... but as it's working for me, I'm not very motivated to investigate further.
Also, don't you need to put
exec 3< <(tail -f -n1 /var/log/kern.log)
in front of
no, actually that would probably be wrong, IIRC. The previous one would be reused by the second loop.
That's right.
