using
Ubuntu 20.04.4 LTS (Focal Fossa)
GNU bash, version 5.1.16(1)
List all drives: UNmounted and mounted
lsblk --noheadings --raw | awk '{print substr($0,0,4)}' | uniq -c | grep 1 | awk '{print "/dev/"$2}' ;
/dev/loop
/dev/sda
/dev/sda1
/dev/sda2
/dev/sda5
/dev/sdb
/dev/sdb1
/dev/sdc
/dev/sdd
/dev/sdd1
From above bash, we have 2 usb sticks c and d as:
/dev/sdc FAT (32-bit version)
/dev/sdd
/dev/sdd1 FAT (32-bit version)
How come sdd has 2 entries?
/dev/sdd
/dev/sdd1 FAT (32-bit version)
How to format usb sdc to get 2 entries like sdd above?
Why?
Because it seems that 2 entries behaves better for
UNmounting usb manually via DISKs and
mounting usb via a bash script below.
Show UNmounted drives and Show Extended Partition Types:
lsblk --noheadings --raw -o NAME,MOUNTPOINT | awk '$1~/[[:digit:]]/ && $2 == ""' ;
Show stats: UNmounted drives and Extended Partition Type:
lsblk --noheadings --raw | awk '$1~/s.*[[:digit:]]/ && $7==""' ;
Mount drives via bash. Then do virus scanning:
lsblk --noheadings --raw | awk '{print substr($0,0,4)}' | uniq -c | grep 1 | awk '{print "/dev/"$2}' | grep -E "(/dev/sd.)[[:digit:]]" | xargs -I{} -n1 udisksctl mount -b {} ;
Mounted /dev/sdd1 at /media/u3/USBstick
/dev/sdc FAT (32-bit version)
is manually UNmounted and
above bash script does not mount /dev/sdc
/dev/sdd
/dev/sdd1 FAT (32-bit version)
is manually UNmounted and
above bash script works.
Mounts sdd
Target is to have bash script mount all drives before a virus scan.
Explain.
Why sdc is only 1 entry versus 2 for sdd?
/dev/sdc FAT (32-bit version)
/dev/sdd
/dev/sdd1 FAT (32-bit version)
Explain.
How to format sdc?
So sdc responds to above bash mount script
like sdd responds.
