Hi, the script works for me on Debian 12 with a Debian Live 11.5.0 ISO with on USB stick /dev/sdb. UUID is 2022-09-10-11-55-02-00. Running it as normal user after minor changes:
destination=2022-09-10-11-55-02-00 destination device is connected. dev=/dev/sdb1 (I changed the value of $destination and the run of "blkid" to "/sbin/blkid".) The output of lsblk -alno NAME,UUID,LABEL | grep 2022-09-10-11-55-02-00 is sdb 2022-09-10-11-55-02-00 d-live 11.5.0 xf amd64 sdb1 2022-09-10-11-55-02-00 d-live 11.5.0 xf amd64 With unplugged USB stick i get the expected line destination device not connected. Aborting. Is the ISO with UUID 2026-01-19-03-28-45-00 downloadable somewhere ? (Maybe its partition table causes strange output of lsblk.) > if ! ( lsblk -alno UUID | grep $destination > /dev/null ); then Seems to work here. Out of superstition i would have avoided the "!" by swapping the then-else-cases and would have put $destination in "-quotation marks. I would next put a line into the script before the if-line like lsblk -alno UUID | grep $destination to see what lsblk actually replies. Have a nice day :) Thomas
