You can use this script to retrieve the name of your USB stick.
The name of your USB stick can be used in Apple’s sudo command to create a USB installer.
Step 1: Open the Terminal application
Step 2: Go to your home directory, type: # cd
Step 3: Optionally create a scripts directory, type: # mkdir scripts
Step 4: Navigate to the newly created scripts directory, type: # cd scripts
Step 5: Create a bash script, type: # vim usbstick.sh
Step 6: Insert the following code:
#!/bin/bash
# Get list of all external physical disks
external_disks=$(diskutil list external physical | grep '^/dev/' | awk '{print $1}')
# Check if any were found
if [[ -z "$external_disks" ]]; then
echo ""
echo "No external USB sticks are connected!"
echo ""
exit 0
fi
echo ""
echo "==="
echo "External USB volumes:"
# Loop through each disk
for disk in $external_disks; do
# Get all partitions for the disk
partitions=$(diskutil list "$disk" | grep '^ [0-9]' | awk '{print $NF}')
for part in $partitions; do
# Get mount info
mount_point=$(diskutil info "$part" | awk -F: '/Mount Point/ {gsub(/^ +| +$/, "", $2); print $2}')
volume_name=$(diskutil info "$part" | awk -F: '/Volume Name/ {gsub(/^ +| +$/, "", $2); print $2}')
fs_type=$(diskutil info "$part" | awk -F: '/Type \(Bundle\)/ {gsub(/^ +| +$/, "", $2); print $2}')
# Only show if it's mounted
if [[ -n "$mount_point" && "$mount_point" != "Not mounted" ]]; then
echo "• Volume: $volume_name"
echo " Mount point: $mount_point"
echo " File system: $fs_type"
echo ""
fi
done
done
Step 7: Make the script executable, type: # chmod +x usbstick.sh
Step 8: Run the script, type: # ./usbstick.sh
Step 9: Press: Enter
Step 10: Below the 3 === characters the name of your USB stick will now appear
Step 11: You can now substitute the volume name in Apple’s sudo command
OR
Step 1: Open the Terminal application
Step 2: Copy and paste the entire code block into the terminal
bash <<'EOF'
